* Fix FindMPI for the intel compiler on linux by looking in implict directories.Bill Hoffman2012-03-201-0/+14
| | | | | | | Use the CMAKE_<LANG>_IMPLICIT_LINK_DIRECTORIES to look for libraries that are in the -showme output from mpi<lang> programs. This is because some libraries reported by -showme are found there, and FindMPI will fail if they are not found.
* FindMPI: Append MPI C++ library correctly in non-compiler case (#12874)Brad King2012-01-161-1/+1
| | | | | | | | When we have no MPI compiler wrapper and search explicitly for the MPI C++ library append it correctly to the list of libraries instead of using a space. Suggested-by: Mourad Boufarguine <bouffa@gmail.com>
* Fix issues with removing try_compile input file.Todd Gamblin2011-06-211-8/+12
| | | | | | - Don't remove input file - Put output in ${CMAKE_CURRENT_BINARY_DIR}${CMAKE_FILES_DIRECTORY} - Remove try_compile variable from the cache after using
* Try regular compiler when no MPI compiler.Todd Gamblin2011-06-211-4/+58
| | | | | | | | If FindMPI can't interrogate any of the available compilers, it attempts to compile simple MPI programs with CMAKE_${lang}_COMPILER. If this works, it uses that as MPI_${lang}_COMPILER. This allows MPI to be discovered on Cray XT/XE systems, where modules are used and cc, CC, and ftn compilers *are* MPI compilers.
* Added backward compatibility for input as well as output vars.Todd Gamblin2011-04-241-4/+30
| | | | | | | Users can now supply MPI_COMPILER, MPI_INCLUDE_PATH, MPI_LIBRARY, and others as with the old FindMPI. These are mapped to their respective equivalents for C and CXX. Fortran is not touched, as there was no Fortran support in the old FindMPI.
* FindMPI: Fix documentation formattingBrad King2011-03-161-24/+16
| | | | | | Adjust whitespace to make the output of "--help-module FindMPI" look good. Also separate the comment containing the copyright and license notice so it does not appear in the documentation.
* FindMPI: Handle multiple languagesTodd Gamblin2011-03-151-295/+477
| | | | | | | | | | | | | | | | | Adds support for: - MPI_<lang>_COMPILER and other useful variables for C, CXX, Fortran - Better compiler interrogation (handles mvapich) - Supports specifying an MPI compiler name directly on the command line without and absolute path, e.g.: cmake -D MPI_CXX_COMPILER=mpixlC - Better compiler name searching tries to match MPI compiler to regular CMAKE_<lang>_COMPILER_ID, if it's available. Gets rid of: - MPI_LIBRARY, MPI_EXTRA_LIBRARY cache variables. These and other old vars are still exported for backward compatibility, but they're not cached.
* Modules: Include builtin FindPackageHandleStandardArgs directlyBrad King2011-01-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The FindPackageHandleStandardArgs module was originally created outside of CMake. It was added for CMake 2.6.0 by commit e118a627 (add a macro FIND_PACKAGE_HANDLE_STANDARD_ARGS..., 2007-07-18). However, it also proliferated into a number of other projects that at the time required only CMake 2.4 and thus could not depend on CMake to provide the module. CMake's own find modules started using the module in commit b5f656e0 (use the new FIND_PACKAGE_HANDLE_STANDARD_ARGS in some of the FindXXX modules..., 2007-07-18). Then commit d358cf5c (add 2nd, more powerful mode to find_package_handle_standard_args, 2010-07-29) added a new feature to the interface of the module that was fully optional and backward compatible with all existing users of the module. Later commit 5f183caa (FindZLIB: use the FPHSA version mode, 2010-08-04) and others shortly thereafter started using the new interface in CMake's own find modules. This change was also backward compatible because it was only an implementation detail within each module. Unforutnately these changes introduced a problem for projects that still have an old copy of FindPackageHandleStandardArgs in CMAKE_MODULE_PATH. When any such project uses one of CMake's builtin find modules the line include(FindPackageHandleStandardArgs) loads the copy from the project which does not have the new interface! Then the including find module tries to use the new interface with the old module and fails. Whether this breakage can be considered a backward incompatible change in CMake is debatable. The situation is analagous to copying a standard library header from one version of a compiler into a project and then observing problems when the next version of the compiler reports errors in its other headers that depend on its new version of the original header. Nevertheless it is a change to CMake that causes problems for projects that worked with previous versions. This problem was discovered during the 2.8.3 release candidate cycle. It is an instance of a more general problem with projects that provide their own versions of CMake modules when other CMake modules depend on them. At the time we resolved this instance of the problem with commit b0118402 (Use absolute path to FindPackageHandleStandardArgs.cmake everywhere, 2010-09-28) for the 2.8.3 release. In order to address the more general problem we introduced policy CMP0017 in commit db44848f (Prefer files from CMAKE_ROOT when including from CMAKE_ROOT, 2010-11-17). That change was followed by commit ce28737c (Remove usage of CMAKE_CURRENT_LIST_DIR now that we have CMP0017, 2010-12-20) which reverted the original workaround in favor of using the policy. However, existing project releases do not set the policy behavior to NEW and therefore still exhibit the problem. We introduced in commit a364daf1 (Allow users to specify defaults for unset policies, 2011-01-03) an option for users to build existing projects by adding -DCMAKE_POLICY_DEFAULT_CMP0017=NEW to the command line. Unfortunately this solution still does not allow such projects to build out of the box, and there is no good way to suggest the use of the new option. The only remaining solution to keep existing projects that exhibit this problem building is to restore the change originally made in commit b0118402 (Use absolute path to FindPackageHandleStandardArgs.cmake everywhere, 2010-09-28). This also avoids policy CMP0017 warnings for this particular instance of the problem the policy addresses.
* Remove usage of CMAKE_CURRENT_LIST_DIR now that we have CMP0017Alex Neundorf2011-01-041-1/+1
| | | | | | | | This puts the new search behaviour for included files in action, i.e. now when a file from Modules/ include()s another file, it also gets the one from Modules/ included, i.e. the one it expects. Alex

| * FindMPI: Fix parsing of mpicc -Wl,-L link flags (#9093)Brad King2010-06-291-2/+2
| | | | | | | | | | | | Commit d84cbd0f (FindMPI: Parse mpicc flags more carefully, 2010-06-24) broke parsing of '-L' flags appearing after '-Wl,' by expecting a preceding space. Update the regular expression to allow '-Wl,-L' too.

| | | | | | | | | | | | Extend the fix from commit 68c7d3e2 (FindMPI: Do not parse -l in middle of library name, 2010-06-24). Parse -D, -I, -L, and -Wl only with preceding spaces or at the beginning of the string.
| * FindMPI: Do not parse -l in middle of library nameBrad King2010-06-241-2/+2
| | | | | | | | | | | | We parse the output of 'mpicc -shome:link' to look for -l options specifying libraries. Fix the parsing regex to avoid matching the string '-l' in the middle of a library name.
* | FindMPI: Trust mpicc -showme on BlueGene/LBrad King2010-06-281-6/+0
|/ | | | | | | | Do not hard-code known BlueGene/L MPI libraries. We do not know their location so the linker cannot find them without the proper -L search path. The MPI compiler tells us about the libraries anyway, and if it does not then the user can fix the problem locally by editing the MPI_EXTRA_LIBRARY cache entry.
