Re: [Matplotlib-users] Building matplotlib from source with libpng (png.h) installed via fink on Mac OS X
2010/8/11 Markus Baden markus.ba...@gmail.com: I'm running Mac OS X 10.5.8. Ok, that explains why it works to flawlessly. When you would be on 10.6, you would probably run into the problem I mentioned, because the software is compiled /also/ for 10.5, and hence with gcc-4.0. Lucky one ;-) - I'm a bit annoyed by this, but it seems, one can load with gcc-4.2 compiled software gcc-4.0 compiled libraries, but not vice versa (i.e. load with a gcc-4.0 compiled program like python from EPD a shared lib compiled with gcc-4.2). Is the EPD you're using both for 10.5 and 10.6?

Are you on OSX 10.5 or 10.6? I'm asking because it's important for others when you're on 10.5 because you're using gcc-4.0 then, while 10.6 users have at least for non-Python (distutils) compilations gcc-4.2 as default.

2010/8/9 Markus Baden markus.ba...@gmail.com: On my Macbook Pro I use Python 2.6 as provided by the Enthought Python Distribution. I ran into some problem with Axes3D so I decided to upgrade to the latest version from source. While trying that I got a similiar error message as discussed in http://www.mail-archive.com/matplotlib-users@lists.sourceforge.net/msg12938.html i.e. error: png.h: No such file or directory In short matplotlib could not find libpng (or png.h from that). I had libpng installed via fink in the usual place /sw/include etc. This seems to be a quite natural choice, so I wondered why matplotlib does not find that out of the box. Following the tips in the above post I looked at basedir in setupext.py For some reason the basedirs for darwin where commented out. Uncommenting the basedirs did the trick for me [1] and matplotlib happily installed with the libpng from fink. Hope this will help other mac users. Thanks for the great work on matplotlib! Thanks for reporting finally a working pure-setup.py installation! But are you sure it really works, because mixing binary-distributed and self-compiled packages often leads to import refusal, when the external libraries (as freetype) are compiled with a different compiler than Python.

Thanks for the warning. Not really sure. So far I have seen no problems, i.e. can happily plot. How can I make sure that I don't ran into those problems? I usually don't mix packages and just hope that the EPD guys update to Matplotlib 1.0 soon.
