Summary0014156: FindPythonLibs: fully support Python on Debian multi-arch systems
DescriptionHello,

I don't know the details but the following patch is needed to make FindPythonLibs properly work on Debian multi-arch systems (that's for future Debian 8.0 and some recent Ubuntu)

http://anonscm.debian.org/gitweb/?p=collab-maint/cmake.git;a=blob;f=debian/patches/multiarch-python-include-dirs.diff;hb=master [^]

In the same time, the patched CMake is causing trouble to build some project. See http://www.na-mic.org/Bug/view.php?id=3116 [^]

@Modestas: Waiting to fix the CMake version of FindPythonLibs.cmake, do you know who should be contacted / what it the process to tweak the module currently provided within Debian ?

Would be helpful if "PYTHON_INCLUDE_DIRS" is appended to the list of path to search when setting "PYTHON_INCLUDE_DIRS2".

Thanks

That would be me. Thanks for letting us know about the problem.

The patch is supposed to be backwards compatible so we will try to fix your problem with the patch. Watch this bug for updates.

I have the same problem with Debian Testing right now.

The patch mentioned above needs another change. JC's idea worked for me:

   find_path(PYTHON_INCLUDE_DIR2
     NAMES pyconfig.h
     PATHS
+ ${PYTHON_INCLUDE_DIR}
       ${PYTHON_FRAMEWORK_INCLUDES}
       [HKEY_LOCAL_MACHINE\\SOFTWARE\\Python\\PythonCore\\${_CURRENT_VERSION}\\InstallPath]/include
       [HKEY_CURRENT_USER\\SOFTWARE\\Python\\PythonCore\\${_CURRENT_VERSION}\\InstallPath]/include

The patch above doesn't work in some cases.

Here is another patch which has to be applied on top of the original patch in the Debian repository.

It looks for pyconfig.h in the original folder PYTHON_INCLUDE_DIR, and uses the alternative location only if the file couldn't be located.

+ find_path(PYTHON_INCLUDE_DIR2
+ NAMES pyconfig.h
+ PATHS
+ ${PYTHON_INCLUDE_DIR}
+ )
+
+ if (NOT PYTHON_INCLUDE_DIR2)
   find_path(PYTHON_INCLUDE_DIR2
     NAMES pyconfig.h
     PATHS

       python${_CURRENT_VERSION}u
       python${_CURRENT_VERSION}
   )
+ endif()

Slicer4 compiles on Debian testing and Ubuntu 13.04 with that change.

It has proven too much work to have pyconfig.h in an multiarch location.

Therefore, pyconfig.h was re-introduced in an non-multiarch location. Instead it is a compatibility header that using compiler macros includes the correct pyconfig.h from a multiarch location.

This patch should be dropped, as it's no longer needed.
