Hi all, I cannot build the latest matplotlib from git. The build log is attached. Nils
It looks like a version mismatch with PyCXX. Was it recently updated or changed? What version of PyCXX do you have? What was the last version of matplotlib that worked for you? You can force matplotlib to use its local copy of PyCXX by uninstalling PyCXX, or adding the following lines to the top of PyCXX::check in setupext.py: self.__class__.found_external = False return "Couldn't import. Using local copy." (But really, we should update setupext so users can specify the local override in setup.cfg).

I wonder if it's commit 6b827cbf. Can you do: git checkout 6b827cbf python setup.py build # confirm it fails git checkout 6b827cbf^ python setup.py build # Does this work?

CXX.check() contains return self._check_for_pkg_config('PyCXX', 'CXX/Extensions.hxx', min_version='6.2.4') which requires version 6.2.4 or later of CXX. Nils has 6.2.3 and so this check should fail and matplotlib should fall back to using the local copy of CXX. SetupPackage._check_for_pkg_config() does check min_version if CXX is installed using pkg-config, but if it is not then min_version is ignored as the function raises a CheckFailed error before min_version is considered. CXX.check() catches this error and uses the system-installed CXX regardless of its version. To check the CXX version we probably need to look in CXX/Version.hxx. I am not sure how to proceed; do you have any ideas Mike? Nils, as a stopgap you could either remove your python-cxx and python-cxx-devel rpms if you don't need them for anything else, or upgrade them to 6.2.4. There is a 6.2.4 on rpm.pbone.net even though there isn't one on packman.links2linux.de. Ian
