* FortranCInterface: Fix support for VS with Intel toolsetBrad King2017-02-011-1/+2
| | | | | | | | | | | | | | | When using a Visual Studio generator with an Intel toolset, such as -T "Intel C++ Compiler XE 14.0" the generated FortranCInterface mangling detection project may fail to build due to `devenv` not working with the `/project ALL_BUILD` option. This seems to be a bug in `devenv` or the Intel VS integration. Work around the problem by building with `/project FortranCInterface` instead. We only need to build this executable and its dependencies within the detection test project anyway. Fixes: #16519
* Simplify CMake per-source license noticesBrad King2016-09-271-13/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | Per-source copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong. Precise contributor information is already maintained automatically by the version control tool. Ultimately it is the receiver of a file who is responsible for determining its licensing status, and per-source notices are merely a convenience. Therefore it is simpler and more accurate for each source to have a generic notice of the license name and references to more detailed information on copyright holders and full license terms. Our `Copyright.txt` file now contains a list of Contributors whose names appeared source-level copyright notices. It also references version control history for more precise information. Therefore we no longer need to spell out the list of Contributors in each source file notice. Replace CMake per-source copyright/license notice headers with a short description of the license and links to `Copyright.txt` and online information available from "https://cmake.org/licensing". The online URL also handles cases of modules being copied out of our source into other projects, so we can drop our notices about replacing links with full license text. Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority of the replacements mechanically. Manually fix up shebang lines and trailing newlines in a few files. Manually update the notices in a few files that the script does not handle.
* Use string(APPEND) in ModulesDaniel Pfeifer2016-07-271-4/+4
| | | | | | | Automate with: find Modules -type f -print0 | xargs -0 perl -i -0pe \ 's/set\(([a-zA-Z0-9_]+)(\s+)"\$\{\1\}([^"])/string(APPEND \1\2"\3/g'
* FortranCInterface: Document mangling result variables publiclyBrad King2016-02-101-0/+52
| | | | | | | Some projects may want to use the detailed mangling information directly instead of using the FortranCInterface_HEADER function. We already provide variables encoding the mangling information, so just document them as available.
* FortranCInterface: Improve documentation formatting and organizationBrad King2016-02-101-70/+78
| | | | | Organize content into sections. Define functions via explicit markup blocks so we can cross-reference them.
* FortranCInterface: Convert docs to a bracket commentBrad King2016-02-101-126/+127
| | | | | Use a bracket comment to hold the documentation instead of a block of line comments. This will make further updates easier.
* FortranCInterface: Do not use cmake_policy(VERSION)Brad King2015-05-191-2/+1
| | | | | | | | | | | Do not force a specific policy version in the module because it prevents projects from setting newer policies to NEW. In particular, projects may want to set CMP0056 to NEW to affect any try_compile calls in this module. Use of this was added in commit v2.8.2~714 (FortranCInterface: Use CMake 2.8.0 behavior, 2009-11-17) in order to set CMP0007 to NEW. Simply set this policy explicitly instead.
* Replace string(REGEX REPLACE) with string(REPLACE) where possibleRolf Eike Beer2014-04-141-1/+1
| | | | The simple replacement is much faster.
* Convert builtin help to reStructuredText source filesKitware Robot2013-10-151-59/+103
| | | | | | | | Run the convert-help.bash script to convert documentation: ./convert-help.bash "/path/to/CMake-build/bin" Then remove it.
* FortranCInterface: Pass all flags to VERIFY project (#13579)Brad King2012-10-101-1/+5
| | | | | | | Teach FortranCInterface_VERIFY to build the test project in a specific configuration and pass all flags for that configuration. This ensures that any modifications made by the user or project to the flag are used in the test project consistently.
* Remove CMake-language block-end command argumentsKitware Robot2012-08-131-1/+1
| | | | | | | | | | | | | | | | | Ancient versions of CMake required else(), endif(), and similar block termination commands to have arguments matching the command starting the block. This is no longer the preferred style. Run the following shell code: for c in else endif endforeach endfunction endmacro endwhile; do echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/' done >convert.sed && git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' | egrep -z -v '^(Utilities/cm|Source/kwsys/)' | egrep -z -v 'Tests/CMakeTests/While-Endwhile-' | xargs -0 sed -i -f convert.sed && rm convert.sed
* FortranCInterface: Work around mingw32-make trouble with parensBrad King2011-12-091-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | The mingw32-make tool does not handle parenthesis in the path to a source file consistently. When CMake is installed in a typical location like "c:\Program Files (x86)\CMake 2.8\" the mingw32-make tool fails on the FortranCInterface detection project sometimes with errors like >mingw32-make -f CMakeFiles\myfort.dir\build.make CMakeFiles/myfort.dir/my_module.f90.obj mingw32-make: *** No rule to make target `x86)/CMake 2.8/share/cmake-2.8/Modules/FortranCInterface/my_module.f90)', needed by `CMakeFiles/myfort.dir/my_module.f90.obj'. Stop. due to parens in the path to the FortranCInterface source directory. However, the behavior varies with the file name of build.make: >copy CMakeFiles\myfort.dir\build.make CMakeFiles\myfort.dir\build2.make >mingw32-make -f CMakeFiles\myfort.dir\build2.make CMakeFiles/myfort.dir/my_module.f90.obj [ 3%] Building Fortran object CMakeFiles/myfort.dir/my_module.f90.obj Tested with >mingw32-make -v GNU Make 3.82 Built for i386-pc-mingw32 Work around the problem by copying the whole FortranCInterface source directory in to the project build tree.

* FortranCInterface: Support '=' in language flagsBrad King2009-12-151-3/+3
| | | | | | | | The commit "FortranCInterface: Honor language flags in checks" taught the FortranCInterface module to pass C and Fortran flags into its detection and verification checks. We improve on the change to allow the '=' character in the language flags. This requires passing the cache entry type with the -D options.
* FortranCInterface: Honor language flags in checksBrad King2009-11-191-0/+3
| | | | | | | We pass CMAKE_C_FLAGS, CMAKE_CXX_FLAGS, and CMAKE_Fortran_FLAGS through try_compile() for the FortranCInterface Detect and Verify projects. This honors user-specified compiler flags for each language, thus supporting flags that affect the Fortran mangling.
* FortranCInterface: Use CMake 2.8.0 behaviorBrad King2009-11-171-0/+7
| | | | | | | The FortranCInterface module should execute with CMake 2.8.0 behavior even if policies are set differently by the including project. In particular, it makes use of empty list elements and therefore expects NEW behavior of CMP0007.
* Convert CMake non-find modules to BSD LicenseBrad King2009-09-281-0/+13
| | | | | | | This adds copyright/license notification blocks CMake's non-find modules. Most of the modules had no notices at all. Some had notices referring to the BSD license already. This commit normalizes existing notices and adds missing notices.
* Make FortranCInterface_VERIFY verbose on failureBrad King2009-09-011-0/+1
| | | | | We enable verbose build output in the try_compile of the simple project. This makes valuable information available in the case of failure.
* Create FortranCInterface_VERIFY functionBrad King2009-08-241-0/+76
| | | | | | | This function builds a simple test project using a combination of Fortran and C (and optionally C++) to verify that the compilers are compatible. The idea is to help projects report very early to users that the compilers specified cannot mix languages.
* Teach FortranCInterface to load outside resultsBrad King2009-08-241-162/+4
| | | | | | | | We split the main detection logic into a Detect.cmake support module and load it only when detection results are not already available. This allows results computed by the main project to be used in try-compile projects without recomputing them. The call to try_compile() need only to pass FortranCInterface_BINARY_DIR through the CMAKE_FLAGS option.
* Teach FortranCInterface to verify languagesBrad King2009-08-201-0/+9
| | | | | This module requires both C and Fortran to be enabled, so error-out if they are not.
* Rewrite FortranCInterface moduleBrad King2009-08-051-214/+317
| | | | | | | | | | | | | | | | | | | | This is a new FortranCInterface.cmake module to replace the previous prototype. All module support files lie in a FortranCInterface directory next to it. This module uses a new approach to detect Fortran symbol mangling. We build a single test project which defines symbols in a Fortran library (one per object-file) and calls them from a Fortran executable. The executable links to a C library which defines symbols encoding all known manglings (one per object-file). The C library falls back to the Fortran library for symbols it cannot provide. Therefore the executable will always link, but prefers the C-implemented symbols when they match. These symbols store string literals of the form INFO:symbol[<name>] so we can parse them out of the executable. This module also provides a simpler interface. It always detects the mangling as soon as it is included. A single macro is provided to generate mangling macros and optionally pre-mangled symbols.
