cxxsupport.cxx not found

[megies]

Is matplotlib supposed to use its included cxxsupport.cxx file in case it is not present in the used python environment / system? If so, the lookup seems to fail in some cases. I can give directions how to reproduce (debian squeeze) if anybody is interested.

Also, the path that is fixed in

matplotlib/setupext.py

Lines 708 to 709 in 7d40606

	# On Fedora 17, these files are installed in /usr/share/CXX
	support_dir = '/usr/src/CXX'

is not valid for Debian. Debian has it in '/usr/share/python2.6/CXX' and (EDIT:) '/usr/share/python2.6/CXX' '/usr/share/python2.7/CXX' instead of '/usr/src/CXX'.

matplotlib is supposed to try to use a system PyCXX first, and fallback to the local installation if that fails. That doesn't always work, given the multitude of different ways that PyCXX is installed. PyCXX is adding support for pkg-config upstream, which should make things much better once that trickles out to the distributions.

You can also manually override to use the locally installed copy using setup.cfg.

Yes -- I'll need something to reproduce and the full build output.

EDIT: setup.cfg doesn't help here. I've been working on too many different things today ;)

punting to 1.4.x due to lack of directions on how to reproduce.

@mdboom This should be irrelevant now that you ripped pycxx out of the c++ layer?

Closing, please re-open if I am wrong.

Yes -- this still affects 1.4.x, but beyond that is a non-issue now that PyCXX is gone.
