cd matplotlib

I have the same error with pip, but when I clone from the git repo, I get a different libpng related error: https://gist.github.com/2269043

Same setup as diimdeep, osx 10.7, xcode 4.3, python 2.7.2 via homebrew, with pip installed for the python from homebrew.

[diimdeep]

my xcode is 4.3.2

@diimdeep: The error you're getting with pip was a bug that was fixed and merged.

@staticfloat: Where does your install of libpng live?

[staticfloat]

@dmcdougall; /usr/X11/include/libpng15

I created a homebrew formula to install libpng12 and link matplotlib with that, and this worked.

[dmcdougall]

Hmmm. I have libpng14 installed via macports and matplotlib compiled successfully from that. Has anybody else had problems getting matplotlib to install with libpng15?

[veeks]

os x 10.7.3
xcode 4.3.2
brew install python v2.7.3

matplotlib install (does not work)
pip - sudo pip install matplotlib
easy_install - sudo easy_install matplotlib
downloading 1.1.0 from source forge and execute 'sudo python setup.py install' - does not work

works:
git clone https://github.com/matplotlib/matplotlib.git
cd matplotlib
python setup.py build
python setup.py install

I did notice that git clone installs matplotlib version 1.2.x whereas the other methods were installing 1.1.x

This has been fixed, see #713

[pelson]

When 1.1.1 is released, #713 means that this will no longer fail. Closing this issue.

I'm runnning matplotlib 1.4.x, yet I get this error:

ImportError: dlopen(/Library/Python/2.7/site-packages/matplotlib-1.4.x-py2.7-macosx-10.9-intel.egg/matplotlib/_png.so, 2): Library not loaded: /usr/local/lib/libpng15.15.dylib
Referenced from: /Library/Python/2.7/site-packages/matplotlib-1.4.x-py2.7-macosx-10.9-intel.egg/matplotlib/_png.so

I have libpng15 installed, but not libpng16.

@roseperrone You should probably create a new issue for this as what ever was going wrong with 1.0 is probably not the same thing going wrong now.

If you think this is a bug in the library please create an issue, if you think it is configuration issues on your machine I would try the mpl mailing list of stackoverflow. In either case you should provide more information about how you installed/configured matplotlib and python. Getting the installation correct an Macs seems to be rather tricky.

[roseperrone]

Thanks, I posted this: http://stackoverflow.com/questions/23099980/matplotlib-says-it-needs-libpng15-but-i-have-libpng16

[mdboom]

This is probably related to the recently posted wheels. @mbrett
