[pypy-dev] cpyext, PyArray, and matplotlib

[Matti Picus]

Stefan H. Muller has been working hard to expand cpyext enough so that 
matplotlib non-interactive backends can work with PyPy. The steps to get 
it all working are included[0]. While pypy translates for him (on MacOS 
I think), I could not get past the platform checks on linux 64. If 
anyone would like to help, the branch is pypy-pyarray and the author is 
Stefan__ on IRC (off work hours).

The traceback is here 
http://buildbot.pypy.org/builders/pypy-c-jit-linux-x86-64/builds/1602/steps/translate/logs/stdio 
the last lines are

[translation:ERROR]  CompilationError: CompilationError(err="""
[translation:ERROR] 	/tmp/usession-pypy-pyarray-0/platcheck_35.o: In function `PyComplex_FromCComplex':
[translation:ERROR] 	platcheck_35.c:(.text+0x13): undefined reference to `_PyComplex_FromCComplex'
