Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The GNU General Public License is a free, copyleft license for software and other kinds of works. The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things. To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others. For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it. For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions. Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users. Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free. The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS 0. Definitions. "This License" refers to version 3 of the GNU General Public License. "Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks. "The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations. To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work. A "covered work" means either the unmodified Program or a work based on the Program. To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well. To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying. An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion. 1. Source Code. The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work. A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language. The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work. The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source. The Corresponding Source for a work in source code form is that same work. 2. Basic Permissions. All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law. You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you. Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary. 3. Protecting Users' Legal Rights From Anti-Circumvention Law. No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures. When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures. 4. Conveying Verbatim Copies. You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee. 5. Conveying Modified Source Versions. You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions: a) The work must carry prominent notices stating that you modified it, and giving a relevant date. b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices". c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so. A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. 6. Conveying Non-Source Forms. You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways: a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange. b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge. c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d. A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work. A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product. "Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM). The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network. Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying. 7. Additional Terms. "Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions. When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission. Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms: a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or d) Limiting the use for publicity purposes of names of licensors or authors of the material; or e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors. All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying. If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms. Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way. 8. Termination. You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11). However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10. 9. Acceptance Not Required for Having Copies. You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so. 10. Automatic Licensing of Downstream Recipients. Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License. An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts. You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it. 11. Patents. A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version". A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License. Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version. In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party. If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid. If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it. A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007. Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law. 12. No Surrender of Others' Freedom. If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program. 13. Use with the GNU Affero General Public License. Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such. 14. Revised Versions of this License. The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation. If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program. Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version. 15. Disclaimer of Warranty. THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. Limitation of Liability. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 17. Interpretation of Sections 15 and 16. If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program. If not, see . Also add information on how to contact you by electronic and paper mail. If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode: Copyright (C) This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, your program's commands might be different; for a GUI interface, you would use an "about box". You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see . The GNU General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License. But first, please read . ffc-2016.2.0/COPYING.LESSER000066400000000000000000000167271301760156400145470ustar00rootroot00000000000000 GNU LESSER GENERAL PUBLIC LICENSE Version 3, 29 June 2007 Copyright (C) 2007 Free Software Foundation, Inc. Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. This version of the GNU Lesser General Public License incorporates the terms and conditions of version 3 of the GNU General Public License, supplemented by the additional permissions listed below. 0. Additional Definitions. As used herein, "this License" refers to version 3 of the GNU Lesser General Public License, and the "GNU GPL" refers to version 3 of the GNU General Public License. "The Library" refers to a covered work governed by this License, other than an Application or a Combined Work as defined below. An "Application" is any work that makes use of an interface provided by the Library, but which is not otherwise based on the Library. Defining a subclass of a class defined by the Library is deemed a mode of using an interface provided by the Library. A "Combined Work" is a work produced by combining or linking an Application with the Library. The particular version of the Library with which the Combined Work was made is also called the "Linked Version". The "Minimal Corresponding Source" for a Combined Work means the Corresponding Source for the Combined Work, excluding any source code for portions of the Combined Work that, considered in isolation, are based on the Application, and not on the Linked Version. The "Corresponding Application Code" for a Combined Work means the object code and/or source code for the Application, including any data and utility programs needed for reproducing the Combined Work from the Application, but excluding the System Libraries of the Combined Work. 1. Exception to Section 3 of the GNU GPL. You may convey a covered work under sections 3 and 4 of this License without being bound by section 3 of the GNU GPL. 2. Conveying Modified Versions. If you modify a copy of the Library, and, in your modifications, a facility refers to a function or data to be supplied by an Application that uses the facility (other than as an argument passed when the facility is invoked), then you may convey a copy of the modified version: a) under this License, provided that you make a good faith effort to ensure that, in the event an Application does not supply the function or data, the facility still operates, and performs whatever part of its purpose remains meaningful, or b) under the GNU GPL, with none of the additional permissions of this License applicable to that copy. 3. Object Code Incorporating Material from Library Header Files. The object code form of an Application may incorporate material from a header file that is part of the Library. You may convey such object code under terms of your choice, provided that, if the incorporated material is not limited to numerical parameters, data structure layouts and accessors, or small macros, inline functions and templates (ten or fewer lines in length), you do both of the following: a) Give prominent notice with each copy of the object code that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the object code with a copy of the GNU GPL and this license document. 4. Combined Works. You may convey a Combined Work under terms of your choice that, taken together, effectively do not restrict modification of the portions of the Library contained in the Combined Work and reverse engineering for debugging such modifications, if you also do each of the following: a) Give prominent notice with each copy of the Combined Work that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the Combined Work with a copy of the GNU GPL and this license document. c) For a Combined Work that displays copyright notices during execution, include the copyright notice for the Library among these notices, as well as a reference directing the user to the copies of the GNU GPL and this license document. d) Do one of the following: 0) Convey the Minimal Corresponding Source under the terms of this License, and the Corresponding Application Code in a form suitable for, and under terms that permit, the user to recombine or relink the Application with a modified version of the Linked Version to produce a modified Combined Work, in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source. 1) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (a) uses at run time a copy of the Library already present on the user's computer system, and (b) will operate properly with a modified version of the Library that is interface-compatible with the Linked Version. e) Provide Installation Information, but only if you would otherwise be required to provide such information under section 6 of the GNU GPL, and only to the extent that such information is necessary to install and execute a modified version of the Combined Work produced by recombining or relinking the Application with a modified version of the Linked Version. (If you use option 4d0, the Installation Information must accompany the Minimal Corresponding Source and Corresponding Application Code. If you use option 4d1, you must provide the Installation Information in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source.) 5. Combined Libraries. You may place library facilities that are a work based on the Library side by side in a single library together with other library facilities that are not Applications and are not covered by this License, and convey such a combined library under terms of your choice, if you do both of the following: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities, conveyed under the terms of this License. b) Give prominent notice with the combined library that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 6. Revised Versions of the GNU Lesser General Public License. The Free Software Foundation may publish revised and/or new versions of the GNU Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library as you received it specifies that a certain numbered version of the GNU Lesser General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that published version or of any later version published by the Free Software Foundation. If the Library as you received it does not specify a version number of the GNU Lesser General Public License, you may choose any version of the GNU Lesser General Public License ever published by the Free Software Foundation. If the Library as you received it specifies that a proxy can decide whether future versions of the GNU Lesser General Public License shall apply, that proxy's public statement of acceptance of any version is permanent authorization for you to choose that version for the Library. ffc-2016.2.0/ChangeLog000066400000000000000000000536351301760156400142710ustar00rootroot000000000000002016.2.0 [2016-11-30] - Jit compiler now compiles elements separately from forms to avoid duplicate work - Add parameter max_signature_length to optionally shorten signatures in the jit cache - Move uflacs module into ffc.uflacs - Remove installation of pkg-config and CMake files (UFC path and compiler flags are available from ffc module) - Add dependency on dijitso and remove dependency on instant - Add experimental Bitbucket pipelines - Tidy the repo after UFC and UFLACS merge, and general spring cleanup.

From a high-level description of the form, it generates efficient low-level C++ code that can be used to assemble the corresponding discrete operator (tensor). In particular, a bilinear form may be assembled into a matrix and a linear form may be assembled into a vector. FFC may be used either from the command line (by invoking the ``ffc`` command) or as a Python module (``import ffc``). FFC is part of the FEniCS Project.

From a high-level description of the form, it generates efficient low-level C++ code that can be used to assemble the corresponding discrete operator (tensor). In particular, a bilinear form may be assembled into a matrix and a linear form may be assembled into a vector. FFC may be used either from the command line (by invoking the ``ffc`` command) or as a Python module (``import ffc``). FFC is part of the FEniCS Project.

The output of each stage is the input of the next stage. Compiler stage 0: Language, parsing ----------------------------------- Input: Python code or .ufl file Output: UFL form This stage consists of parsing and expressing a form in the UFL form language. This stage is completely handled by UFL. Compiler stage 1: Analysis -------------------------- Input: UFL form Output: Preprocessed UFL form and FormData (metadata) This stage preprocesses the UFL form and extracts form metadata. It may also perform simplifications on the form. Compiler stage 2: Code representation ------------------------------------- Input: Preprocessed UFL form and FormData (metadata) Output: Intermediate Representation (IR) This stage examines the input and generates all data needed for code generation. This includes generation of finite element basis functions, extraction of data for mapping of degrees of freedom and possible precomputation of integrals. Most of the complexity of compilation is handled in this stage. The IR is stored as a dictionary, mapping names of UFC functions to data needed for generation of the corresponding code. Compiler stage 3: Optimization ------------------------------ Input: Intermediate Representation (IR) Output: Optimized Intermediate Representation (OIR) This stage examines the IR and performs optimizations. Optimization is currently disabled as a separate stage but is implemented as part of the code generation for quadrature representation. Compiler stage 4: Code generation --------------------------------- Input: Optimized Intermediate Representation (OIR) Output: C++ code This stage examines the OIR and generates the actual C++ code for the body of each UFC function. The code is stored as a dictionary, mapping names of UFC functions to strings containing the C++ code of the body of each function. Compiler stage 5: Code formatting --------------------------------- Input: C++ code Output: C++ code files This stage examines the generated C++ code and formats it according to the UFC format, generating as output one or more .h/.cpp files conforming to the UFC format. The main interface is defined by the following two functions: compile_form compile_element The compiler stages are implemented by the following functions: analyze_forms or analyze_elements (stage 1) compute_ir (stage 2) optimize_ir (stage 3) generate_code (stage 4) format_code (stage 5) """ # Copyright (C) 2007-2016 Anders Logg # # This file is part of FFC. # # FFC is free software: you can redistribute it and/or modify # it under the terms of the GNU Lesser General Public License as published by # the Free Software Foundation, either version 3 of the License, or # (at your option) any later version. # # FFC is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

These evaluate the degree of freedom (dof) number i and all degrees of freedom for an element respectively. Each dof L is assumed to act on a field f in the following manner: L(f) = w_{j, k} f_k(x_j) where w is a set of weights, j is an index set corresponding to the number of points involved in the evaluation of the functional, and k is a multi-index set with rank corresponding to the value rank of the function f. For common degrees of freedom such as point evaluations and directional component evaluations, there is just one point. However, for various integral moments, the integrals are evaluated using quadrature. The number of points therefore correspond to the quadrature points. The points x_j, weights w_{j, k} and components k are extracted from FIAT (functional.pt_dict) in the intermediate representation stage.

Changes for 1.6.0: * New feature: ADD_FAILURE_AT() for reporting a test failure at the given source location -- useful for writing testing utilities. * New feature: the universal value printer is moved from Google Mock to Google Test. * New feature: type parameters and value parameters are reported in the XML report now. * A gtest_disable_pthreads CMake option. * Colored output works in GNU Screen sessions now. * Parameters of value-parameterized tests are now printed in the textual output. * Failures from ad hoc test assertions run before RUN_ALL_TESTS() are now correctly reported. * Arguments of ASSERT_XY and EXPECT_XY no longer need to support << to ostream. * More complete handling of exceptions. * GTEST_ASSERT_XY can be used instead of ASSERT_XY in case the latter name is already used by another library. * --gtest_catch_exceptions is now true by default, allowing a test program to continue after an exception is thrown. * Value-parameterized test fixtures can now derive from Test and WithParamInterface separately, easing conversion of legacy tests. * Death test messages are clearly marked to make them more distinguishable from other messages. * Compatibility fixes for Android, Google Native Client, MinGW, HP UX, PowerPC, Lucid autotools, libCStd, Sun C++, Borland C++ Builder (Code Gear), IBM XL C++ (Visual Age C++), and C++0x. * Bug fixes and implementation clean-ups. * Potentially incompatible changes: disables the harmful 'make install' command in autotools. Changes for 1.5.0: * New feature: assertions can be safely called in multiple threads where the pthreads library is available. * New feature: predicates used inside EXPECT_TRUE() and friends can now generate custom failure messages. * New feature: Google Test can now be compiled as a DLL. * New feature: fused source files are included. * New feature: prints help when encountering unrecognized Google Test flags. * Experimental feature: CMake build script (requires CMake 2.6.4+). * Experimental feature: the Pump script for meta programming. * double values streamed to an assertion are printed with enough precision to differentiate any two different values. * Google Test now works on Solaris and AIX. * Build and test script improvements. * Bug fixes and implementation clean-ups. Potentially breaking changes: * Stopped supporting VC++ 7.1 with exceptions disabled. * Dropped support for 'make install'. Changes for 1.4.0: * New feature: the event listener API * New feature: test shuffling * New feature: the XML report format is closer to junitreport and can be parsed by Hudson now. * New feature: when a test runs under Visual Studio, its failures are integrated in the IDE. * New feature: /MD(d) versions of VC++ projects. * New feature: elapsed time for the tests is printed by default. * New feature: comes with a TR1 tuple implementation such that Boost is no longer needed for Combine(). * New feature: EXPECT_DEATH_IF_SUPPORTED macro and friends. * New feature: the Xcode project can now produce static gtest libraries in addition to a framework. * Compatibility fixes for Solaris, Cygwin, minGW, Windows Mobile, Symbian, gcc, and C++Builder. * Bug fixes and implementation clean-ups. Changes for 1.3.0: * New feature: death tests on Windows, Cygwin, and Mac. * New feature: ability to use Google Test assertions in other testing frameworks. * New feature: ability to run disabled test via --gtest_also_run_disabled_tests. * New feature: the --help flag for printing the usage. * New feature: access to Google Test flag values in user code. * New feature: a script that packs Google Test into one .h and one .cc file for easy deployment. * New feature: support for distributing test functions to multiple machines (requires support from the test runner). * Bug fixes and implementation clean-ups. Changes for 1.2.1: * Compatibility fixes for Linux IA-64 and IBM z/OS. * Added support for using Boost and other TR1 implementations. * Changes to the build scripts to support upcoming release of Google C++ Mocking Framework. * Added Makefile to the distribution package. * Improved build instructions in README. Changes for 1.2.0: * New feature: value-parameterized tests. * New feature: the ASSERT/EXPECT_(NON)FATAL_FAILURE(_ON_ALL_THREADS) macros. * Changed the XML report format to match JUnit/Ant's. * Added tests to the Xcode project. * Added scons/SConscript for building with SCons. * Added src/gtest-all.cc for building Google Test from a single file. * Fixed compatibility with Solaris and z/OS. * Enabled running Python tests on systems with python 2.3 installed, e.g. Mac OS X 10.4. * Bug fixes. Changes for 1.1.0: * New feature: type-parameterized tests. * New feature: exception assertions. * New feature: printing elapsed time of tests. * Improved the robustness of death tests. * Added an Xcode project and samples. * Adjusted the output format on Windows to be understandable by Visual Studio. * Minor bug fixes. Changes for 1.0.1: * Added project files for Visual Studio 7.1. * Fixed issues with compiling on Mac OS X. * Fixed issues with compiling on Cygwin.

Based on the xUnit architecture. Supports automatic test discovery, a rich set of assertions, user-defined assertions, death tests, fatal and non-fatal failures, various options for running the tests, and XML test report generation. Please see the project page above for more information as well as the mailing list for questions, discussions, and development. There is also an IRC channel on OFTC (irc.oftc.net) #gtest available. Please join us! Requirements for End Users -------------------------- Google Test is designed to have fairly minimal requirements to build and use with your projects, but there are some. Currently, we support Linux, Windows, Mac OS X, and Cygwin. We will also make our best effort to support other platforms (e.g. Solaris, AIX, and z/OS). However, since core members of the Google Test project have no access to these platforms, Google Test may have outstanding issues there. If you notice any problems on your platform, please notify googletestframework@googlegroups.com. Patches for fixing them are even more welcome! ### Linux Requirements ### These are the base requirements to build and use Google Test from a source package (as described below): * GNU-compatible Make or gmake * POSIX-standard shell * POSIX(-2) Regular Expressions (regex.h) * A C++98-standard-compliant compiler ### Windows Requirements ### * Microsoft Visual C++ 7.1 or newer ### Cygwin Requirements ### * Cygwin 1.5.25-14 or newer ### Mac OS X Requirements ### * Mac OS X 10.4 Tiger or newer * Developer Tools Installed Also, you'll need CMake 2.6.4 or higher if you want to build the samples using the provided CMake script, regardless of the platform. Requirements for Contributors ----------------------------- We welcome patches. If you plan to contribute a patch, you need to build Google Test and its own tests from an SVN checkout (described below), which has further requirements: * Python version 2.3 or newer (for running some of the tests and re-generating certain source files from templates) * CMake 2.6.4 or newer Getting the Source ------------------ There are two primary ways of getting Google Test's source code: you can download a stable source release in your preferred archive format, or directly check out the source from our Subversion (SVN) repositary. The SVN checkout requires a few extra steps and some extra software packages on your system, but lets you track the latest development and make patches much more easily, so we highly encourage it. ### Source Package ### Google Test is released in versioned source packages which can be downloaded from the download page [1]. Several different archive formats are provided, but the only difference is the tools used to manipulate them, and the size of the resulting file. Download whichever you are most comfortable with. [1] http://code.google.com/p/googletest/downloads/list Once the package is downloaded, expand it using whichever tools you prefer for that type. This will result in a new directory with the name "gtest-X.Y.Z" which contains all of the source code. Here are some examples on Linux: tar -xvzf gtest-X.Y.Z.tar.gz tar -xvjf gtest-X.Y.Z.tar.bz2 unzip gtest-X.Y.Z.zip ### SVN Checkout ### To check out the main branch (also known as the "trunk") of Google Test, run the following Subversion command: svn checkout http://googletest.googlecode.com/svn/trunk/ gtest-svn Setting up the Build -------------------- To build Google Test and your tests that use it, you need to tell your build system where to find its headers and source files. The exact way to do it depends on which build system you use, and is usually straightforward. ### Generic Build Instructions ### Suppose you put Google Test in directory ${GTEST_DIR}. To build it, create a library build target (or a project as called by Visual Studio and Xcode) to compile ${GTEST_DIR}/src/gtest-all.cc with ${GTEST_DIR}/include in the system header search path and ${GTEST_DIR} in the normal header search path. Assuming a Linux-like system and gcc, something like the following will do: g++ -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \ -pthread -c ${GTEST_DIR}/src/gtest-all.cc ar -rv libgtest.a gtest-all.o (We need -pthread as Google Test uses threads.) Next, you should compile your test source file with ${GTEST_DIR}/include in the system header search path, and link it with gtest and any other necessary libraries: g++ -isystem ${GTEST_DIR}/include -pthread path/to/your_test.cc libgtest.a \ -o your_test As an example, the make/ directory contains a Makefile that you can use to build Google Test on systems where GNU make is available (e.g. Linux, Mac OS X, and Cygwin). It doesn't try to build Google Test's own tests. Instead, it just builds the Google Test library and a sample test. You can use it as a starting point for your own build script. If the default settings are correct for your environment, the following commands should succeed: cd ${GTEST_DIR}/make make ./sample1_unittest If you see errors, try to tweak the contents of make/Makefile to make them go away. There are instructions in make/Makefile on how to do it. ### Using CMake ### Google Test comes with a CMake build script (CMakeLists.txt) that can be used on a wide range of platforms ("C" stands for cross-platofrm.). If you don't have CMake installed already, you can download it for free from http://www.cmake.org/. CMake works by generating native makefiles or build projects that can be used in the compiler environment of your choice. The typical workflow starts with: mkdir mybuild # Create a directory to hold the build output. cd mybuild cmake ${GTEST_DIR} # Generate native build scripts. If you want to build Google Test's samples, you should replace the last command with cmake -Dgtest_build_samples=ON ${GTEST_DIR} If you are on a *nix system, you should now see a Makefile in the current directory. Just type 'make' to build gtest. If you use Windows and have Vistual Studio installed, a gtest.sln file and several .vcproj files will be created. You can then build them using Visual Studio. On Mac OS X with Xcode installed, a .xcodeproj file will be generated. ### Legacy Build Scripts ### Before settling on CMake, we have been providing hand-maintained build projects/scripts for Visual Studio, Xcode, and Autotools. While we continue to provide them for convenience, they are not actively maintained any more. We highly recommend that you follow the instructions in the previous two sections to integrate Google Test with your existing build system. If you still need to use the legacy build scripts, here's how: The msvc\ folder contains two solutions with Visual C++ projects. Open the gtest.sln or gtest-md.sln file using Visual Studio, and you are ready to build Google Test the same way you build any Visual Studio project. Files that have names ending with -md use DLL versions of Microsoft runtime libraries (the /MD or the /MDd compiler option). Files without that suffix use static versions of the runtime libraries (the /MT or the /MTd option). Please note that one must use the same option to compile both gtest and the test code. If you use Visual Studio 2005 or above, we recommend the -md version as /MD is the default for new projects in these versions of Visual Studio. On Mac OS X, open the gtest.xcodeproj in the xcode/ folder using Xcode. Build the "gtest" target. The universal binary framework will end up in your selected build directory (selected in the Xcode "Preferences..." -> "Building" pane and defaults to xcode/build). Alternatively, at the command line, enter: xcodebuild This will build the "Release" configuration of gtest.framework in your default build location. See the "xcodebuild" man page for more information about building different configurations and building in different locations. If you wish to use the Google Test Xcode project with Xcode 4.x and above, you need to either: * update the SDK configuration options in xcode/Config/General.xconfig. Comment options SDKROOT, MACOS_DEPLOYMENT_TARGET, and GCC_VERSION. If you choose this route you lose the ability to target earlier versions of MacOS X. * Install an SDK for an earlier version. This doesn't appear to be supported by Apple, but has been reported to work (http://stackoverflow.com/questions/5378518). Tweaking Google Test -------------------- Google Test can be used in diverse environments. The default configuration may not work (or may not work well) out of the box in some environments. However, you can easily tweak Google Test by defining control macros on the compiler command line. Generally, these macros are named like GTEST_XYZ and you define them to either 1 or 0 to enable or disable a certain feature. We list the most frequently used macros below. For a complete list, see file include/gtest/internal/gtest-port.h. ### Choosing a TR1 Tuple Library ### Some Google Test features require the C++ Technical Report 1 (TR1) tuple library, which is not yet available with all compilers. The good news is that Google Test implements a subset of TR1 tuple that's enough for its own need, and will automatically use this when the compiler doesn't provide TR1 tuple. Usually you don't need to care about which tuple library Google Test uses. However, if your project already uses TR1 tuple, you need to tell Google Test to use the same TR1 tuple library the rest of your project uses, or the two tuple implementations will clash. To do that, add -DGTEST_USE_OWN_TR1_TUPLE=0 to the compiler flags while compiling Google Test and your tests. If you want to force Google Test to use its own tuple library, just add -DGTEST_USE_OWN_TR1_TUPLE=1 to the compiler flags instead. If you don't want Google Test to use tuple at all, add -DGTEST_HAS_TR1_TUPLE=0 and all features using tuple will be disabled. ### Multi-threaded Tests ### Google Test is thread-safe where the pthread library is available. After #include "gtest/gtest.h", you can check the GTEST_IS_THREADSAFE macro to see whether this is the case (yes if the macro is #defined to 1, no if it's undefined.). If Google Test doesn't correctly detect whether pthread is available in your environment, you can force it with -DGTEST_HAS_PTHREAD=1 or -DGTEST_HAS_PTHREAD=0 When Google Test uses pthread, you may need to add flags to your compiler and/or linker to select the pthread library, or you'll get link errors. If you use the CMake script or the deprecated Autotools script, this is taken care of for you. If you use your own build script, you'll need to read your compiler and linker's manual to figure out what flags to add. ### As a Shared Library (DLL) ### Google Test is compact, so most users can build and link it as a static library for the simplicity. You can choose to use Google Test as a shared library (known as a DLL on Windows) if you prefer. To compile *gtest* as a shared library, add -DGTEST_CREATE_SHARED_LIBRARY=1 to the compiler flags. You'll also need to tell the linker to produce a shared library instead - consult your linker's manual for how to do it. To compile your *tests* that use the gtest shared library, add -DGTEST_LINKED_AS_SHARED_LIBRARY=1 to the compiler flags. Note: while the above steps aren't technically necessary today when using some compilers (e.g. GCC), they may become necessary in the future, if we decide to improve the speed of loading the library (see http://gcc.gnu.org/wiki/Visibility for details). Therefore you are recommended to always add the above flags when using Google Test as a shared library. Otherwise a future release of Google Test may break your build script. ### Avoiding Macro Name Clashes ### In C++, macros don't obey namespaces. Therefore two libraries that both define a macro of the same name will clash if you #include both definitions. In case a Google Test macro clashes with another library, you can force Google Test to rename its macro to avoid the conflict. Specifically, if both Google Test and some other code define macro FOO, you can add -DGTEST_DONT_DEFINE_FOO=1 to the compiler flags to tell Google Test to change the macro's name from FOO to GTEST_FOO. Currently FOO can be FAIL, SUCCEED, or TEST. For example, with -DGTEST_DONT_DEFINE_TEST=1, you'll need to write GTEST_TEST(SomeTest, DoesThis) { ... } instead of TEST(SomeTest, DoesThis) { ... } in order to define a test. Upgrating from an Earlier Version --------------------------------- We strive to keep Google Test releases backward compatible. Sometimes, though, we have to make some breaking changes for the users' long-term benefits. This section describes what you'll need to do if you are upgrading from an earlier version of Google Test. ### Upgrading from 1.3.0 or Earlier ### You may need to explicitly enable or disable Google Test's own TR1 tuple library. See the instructions in section "Choosing a TR1 Tuple Library". ### Upgrading from 1.4.0 or Earlier ### The Autotools build script (configure + make) is no longer officially supportted. You are encouraged to migrate to your own build system or use CMake. If you still need to use Autotools, you can find instructions in the README file from Google Test 1.4.0. On platforms where the pthread library is available, Google Test uses it in order to be thread-safe. See the "Multi-threaded Tests" section for what this means to your build script. If you use Microsoft Visual C++ 7.1 with exceptions disabled, Google Test will no longer compile. This should affect very few people, as a large portion of STL (including ) doesn't compile in this mode anyway. We decided to stop supporting it in order to greatly simplify Google Test's implementation. Developing Google Test ---------------------- This section discusses how to make your own changes to Google Test. ### Testing Google Test Itself ### To make sure your changes work as intended and don't break existing functionality, you'll want to compile and run Google Test's own tests. For that you can use CMake: mkdir mybuild cd mybuild cmake -Dgtest_build_tests=ON ${GTEST_DIR} Make sure you have Python installed, as some of Google Test's tests are written in Python. If the cmake command complains about not being able to find Python ("Could NOT find PythonInterp (missing: PYTHON_EXECUTABLE)"), try telling it explicitly where your Python executable can be found: cmake -DPYTHON_EXECUTABLE=path/to/python -Dgtest_build_tests=ON ${GTEST_DIR} Next, you can build Google Test and all of its own tests. On *nix, this is usually done by 'make'. To run the tests, do make test All tests should pass. ### Regenerating Source Files ### Some of Google Test's source files are generated from templates (not in the C++ sense) using a script. A template file is named FOO.pump, where FOO is the name of the file it will generate. For example, the file include/gtest/internal/gtest-type-util.h.pump is used to generate gtest-type-util.h in the same directory. Normally you don't need to worry about regenerating the source files, unless you need to modify them. In that case, you should modify the corresponding .pump files instead and run the pump.py Python script to regenerate them. You can find pump.py in the scripts/ directory. Read the Pump manual [2] for how to use it. [2] http://code.google.com/p/googletest/wiki/PumpManual ### Contributing a Patch ### We welcome patches. Please read the Google Test developer's guide [3] for how you can contribute. In particular, make sure you have signed the Contributor License Agreement, or we won't be able to accept the patch.

The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run.

That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

In that // case, please try to rewrite your regular expression within the // above syntax. // // This implementation is *not* meant to be as highly tuned or robust // as a compiled regex library, but should perform well enough for a // death test, which already incurs significant overhead by launching // a child process. // // Known caveats: // // A "threadsafe" style death test obtains the path to the test // program from argv[0] and re-executes it in the sub-process.

It is usually derived from testing::TestWithParam (see below for // another inheritance scheme that's sometimes useful in more complicated // class hierarchies), where the type of your parameter values. // TestWithParam is itself derived from testing::Test. T can be any // copyable type. If it's a raw pointer, you are responsible for managing the // lifespan of the pointed values. class FooTest : public ::testing::TestWithParam { // You can implement all the usual class fixture members here. }; // Then, use the TEST_P macro to define as many parameterized tests // for this fixture as you want. The _P suffix is for "parameterized" // or "pattern", whichever you prefer to think. TEST_P(FooTest, DoesBlah) { // Inside a test, access the test parameter with the GetParam() method // of the TestWithParam class: EXPECT_TRUE(foo.Blah(GetParam())); ... } TEST_P(FooTest, HasBlahBlah) { ... } // Finally, you can use INSTANTIATE_TEST_CASE_P to instantiate the test // case with any set of parameters you want. Google Test defines a number // of functions for generating test parameters. They return what we call // (surprise!) parameter generators. Here is a summary of them, which // are all in the testing namespace: // // // Range(begin, end [, step]) - Yields values {begin, begin+step, // begin+step+step, ...}. The values do not // include end. step defaults to 1. // Values(v1, v2, ..., vN) - Yields values {v1, v2, ..., vN}. // ValuesIn(container) - Yields values from a C-style array, an STL // ValuesIn(begin,end) container, or an iterator range [begin, end). // Bool() - Yields sequence {false, true}. // Combine(g1, g2, ..., gN) - Yields all combinations (the Cartesian product // for the math savvy) of the values generated // by the N generators. // // For more details, see comments at the definitions of these functions below // in this file. // // The following statement will instantiate tests from the FooTest test case // each with parameter values "meeny", "miny", and "moe". INSTANTIATE_TEST_CASE_P(InstantiationName, FooTest, Values("meeny", "miny", "moe")); // To distinguish different instances of the pattern, (yes, you // can instantiate it more then once) the first argument to the // INSTANTIATE_TEST_CASE_P macro is a prefix that will be added to the // actual test case name. Remember to pick unique prefixes for different // instantiations. The tests from the instantiation above will have // these names: // // * InstantiationName/FooTest.DoesBlah/0 for "meeny" // * InstantiationName/FooTest.DoesBlah/1 for "miny" // * InstantiationName/FooTest.DoesBlah/2 for "moe" // * InstantiationName/FooTest.HasBlahBlah/0 for "meeny" // * InstantiationName/FooTest.HasBlahBlah/1 for "miny" // * InstantiationName/FooTest.HasBlahBlah/2 for "moe" // // You can use these names in --gtest_filter. // // This statement will instantiate all tests from FooTest again, each // with parameter values "cat" and "dog": const char* pets[] = {"cat", "dog"}; INSTANTIATE_TEST_CASE_P(AnotherInstantiationName, FooTest, ValuesIn(pets)); // The tests from the instantiation above will have these names: // // * AnotherInstantiationName/FooTest.DoesBlah/0 for "cat" // * AnotherInstantiationName/FooTest.DoesBlah/1 for "dog" // * AnotherInstantiationName/FooTest.HasBlahBlah/0 for "cat" // * AnotherInstantiationName/FooTest.HasBlahBlah/1 for "dog" // // Please note that INSTANTIATE_TEST_CASE_P will instantiate all tests // in the given test case, whether their definitions come before or // AFTER the INSTANTIATE_TEST_CASE_P statement. // // Please also note that generator expressions (including parameters to the // generators) are evaluated in InitGoogleTest(), after main() has started. // This allows the user on one hand, to adjust generator parameters in order // to dynamically determine a set of tests to run and on the other hand, // give the user a chance to inspect the generated tests with Google Test // reflection API before RUN_ALL_TESTS() is executed. // // You can see samples/sample7_unittest.cc and samples/sample8_unittest.cc // for more examples. // // In the future, we plan to publish the API for defining new parameter // generators.

(The user can also force certain dnl compiler flags/libs to be tested by setting these environment dnl variables.) dnl dnl Also sets PTHREAD_CC to any special C compiler that is needed for dnl multi-threaded programs (defaults to the value of CC otherwise). dnl (This is necessary on AIX to use the special cc_r compiler alias.) dnl dnl NOTE: You are assumed to not only compile your program with these dnl flags, but also link it with them as well. e.g. you should link dnl with $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS dnl $LIBS dnl dnl If you are only building threads programs, you may wish to use dnl these variables in your default LIBS, CFLAGS, and CC: dnl dnl LIBS="$PTHREAD_LIBS $LIBS" dnl CFLAGS="$CFLAGS $PTHREAD_CFLAGS" dnl CC="$PTHREAD_CC" dnl dnl In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute dnl constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to dnl that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX). dnl dnl ACTION-IF-FOUND is a list of shell commands to run if a threads dnl library is found, and ACTION-IF-NOT-FOUND is a list of commands to dnl run it if it is not found. If ACTION-IF-FOUND is not specified, the dnl default action will define HAVE_PTHREAD. dnl dnl Please let the authors know if this macro fails on any platform, or dnl if you have any other suggestions or comments. This macro was based dnl on work by SGJ on autoconf scripts for FFTW (www.fftw.org) (with dnl help from M. Frigo), as well as ac_pthread and hb_pthread macros dnl posted by Alejandro Forero Cuervo to the autoconf macro repository. dnl We are also grateful for the helpful feedback of numerous users. dnl dnl @category InstalledPackages dnl @author Steven G.

"""fuse_gtest_files.py v0.2.0 Fuses Google Test source code into a .h file and a .cc file. SYNOPSIS fuse_gtest_files.py [GTEST_ROOT_DIR] OUTPUT_DIR Scans GTEST_ROOT_DIR for Google Test source code, and generates two files: OUTPUT_DIR/gtest/gtest.h and OUTPUT_DIR/gtest/gtest-all.cc. Then you can build your tests by adding OUTPUT_DIR to the include search path and linking with OUTPUT_DIR/gtest/gtest-all.cc. These two files contain everything you need to use Google Test. Hence you can "install" Google Test by copying them to wherever you want. GTEST_ROOT_DIR can be omitted and defaults to the parent directory of the directory holding this script. EXAMPLES ./fuse_gtest_files.py fused_gtest ./fuse_gtest_files.py path/to/unpacked/gtest fused_gtest This tool is experimental. In particular, it assumes that there is no conditional inclusion of Google Test headers. Please report any problems to googletestframework@googlegroups.com.

How to update references ======================== To update the references for the FFC regression tests, first commit your changes, then run the regression test (to generate the new references) and finally run the script upload: cd /tests/regression/ python test.py ./scripts/upload Note: You may be asked for your *Bitbucket* username and password when uploading the reference data, if use of ssh keys fails. Note: The upload script will push the new references to the ffc-reference-data repository. This is harmless even if these references are not needed later. Note: The upload script will update the file ffc-regression-data-id and commit this change to the currently active branch, remember to include this commit when merging or pushing your changes elsewhere. Note: You can cherry-pick the commit that updated ffc-regression-data-id into another branch to use the same set of references there. Note: If you ever get merge conflicts in the ffc-regression-data-id, always pick one version of the file. Most likely you'll need to update the references again. How to run regression tests against a different set of regression data ====================================================================== To run regression tests and compare to a different set of regression data, perhaps to see what has changed in generated code since a certain version, check out the ffc-regression-data-id file you want and run tests as usual cd /tests/regression/ git checkout ffc-regression-data-id python test.py The test.py script will run scripts/download which will check out the regression data with the commit id from ffc-regression-data-id in ffc-regression-data/.
