* Remove CMake-language block-end command argumentsKitware Robot2012-08-131-6/+6
| | | | | | | | | | | | | | | | | 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

| * FindPythonInterp: rework the version detectionRolf Eike Beer2012-02-271-16/+35
| | | | | | | | | | | | | | | | | | There are versions out there that neither understand --version nor -V. Try a completely different approach: execute a small python script that prints the version number (and only that) in an easily reusable way using sys.version_info. This is documented to work since Python 2.0. Use sys.version for older versions, which is documented to exist since 1.5. If even that doesn't work then simply assume we are on 1.4.0.
* | FindPython{Interp,Libs}: document Python_ADDITIONAL_VERSIONS as inputRolf Eike Beer2012-02-221-1/+3
|/ | | | | The current documentation could be read as if that variable is output from the module, which is nonsense.

* FindPythonInterp: fix version parsingRolf Eike Beer2012-01-191-5/+9
| | | | | | | | | | | | | | On dashmacmini2 the test showed output like this: -- Found PythonInterp: /usr/bin/python (found version "Unknown option: -- usage: /usr/bin/python [option] ... [-c cmd | file | -] [arg] ... Try `python -h' for more information.") On my machine where python outputs "Python 2.7" this worked, but PYTHON_VERSION_MAJOR, PYTHON_VERSION_MINOR, and PYTHON_VERSION_PATCH were all set to "2.7". Add some checks that the version output has the expected form before using it.
* FindPythonInterp: make version selectableRolf Eike Beer2012-01-181-2/+39
| | | | | | | | This allows the developer to tell FindPythonInterp which Python version should be searched for. This allows the right version to be chosen for a project without user assistance if there are specific requirements. This is especially useful as it is common to have major versions 2 and 3 installed in parallel, which are partly incompatible.
* Use FIND_PACKAGE_HANDLE_STANDARD_ARGS second modeBjörn Ricks2011-08-231-1/+1
| | | | | | Using the second mode of FIND_PACKAGE_HANDLE_STANDARD_ARGS allows for checking the version number. Now a user can require a minimum version of the python interpreter with find_package(PythonInterp VERSION)
* Update documentation of FindPythonInterp.cmakeBjörn Ricks2011-08-231-3/+10

* Determine python versionBjörn Ricks2011-08-231-0/+7
| | | | | Use PYTHON_EXECUTABLE to determine PYTHON_VERSION_STRING, PYTHON_VERSION_MINOR, PYTHON_VERSION_MAJOR and PYTHON_VERSION_PATCH
* Search for the installed python interpreter firstBjörn Ricks2011-08-231-12/+13
| | | | | | | | | | | | | The old approach to determine the python executeable chooses the newest version from _Python_VERSIONS if no additonal versions are passed. With python it is possible to install different versions side-by-side. Therefore a user can install e.g. python 2.5 and 2.7. Python 2.7 maybe only installed for testing new features and 2.5 for building and running his software. Thus the default installation for the user would be python 2.5 and then returning PYTHON_EXECUTEABLE python2.7 would be wrong. The new approuch searches first for the the default python executable e.g. /usr/bin/python on unix and if it can't be found _Python_VERSIONS is used.
* 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.

| | | | | | | | | | | | | | | | 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
* | Python additional version support, bug #10279.Marcus D. Hanwell2011-01-101-19/+27
|/ | | | | | Introduced an additional variable, Python_ADDITIONAL_VERSIONS, to both FindPythonLibs and FindPythonInterp. Changed FindPythonInterp to loop over versions rather than hardcoding all versions (more like libs).
* Use absolute path to FindPackageHandleStandardArgs.cmake everywhereAlex Neundorf2010-09-281-1/+1
| | | | | | | This is to avoid getting an (older) copy of FPHSA.cmake which is e.g. installed with KDE 4.5.0 and 4.5.1. Alex
