Description
I've tried to install matplotlib using pip on Linux and it couldn't find freetype during the build process, even though it's installed with dev packages.
freetype: no [The C/C++ header for freetype2 (ft2build.h)
could not be found. You may need to install the
development package.]
But:
$ ls -l /usr/include/freetype2/ft2build.h
-rw-r--r-- 1 root root 2383 Mar 13 17:29 /usr/include/freetype2/ft2build.h
And:
$ freetype-config --cflags
-I/usr/include/freetype2

Can you provide any more details (distribution, version etc)?

Linux: Ubuntu 14.04 LTS
Libraries:
libfreetype6:amd64 2.5.2-1ubuntu2
libfreetype6-dev 2.5.2-1ubuntu2
Matplotlib matplotlib==1.3.1 (from pip)
I've checked the
setupext.pyand it looks that for freetype it only checks for theft2build.hin /usr/include and not in/usr/include/freetype2even though it's added to list of checked directories for FreeType.tacaswell commentedon May 1, 2014
I can not reproduce this in a virtual environment on 14.04.
kmike commentedon May 2, 2014
It looks similar to #2623. Even if it is not the same issue, are there plans for 1.3.2? :)

I have the same problem. I try to install matplotlib in a virtual environment on ubuntu server 14.04. freetype-devel has been installed (package
libfreetype6-dev):But matplotlib does not find it.

@espdev What version of mpl?
espdev commentedon May 7, 2014
@tacaswell Version 1.3.1 from PyPI.

A temporary fix would be to create a symlink before installing matplotlib using pip.
steko commentedon May 24, 2014
I found the same issue on Debian unstable with Matplotlib 1.3.1 (both from PyPI and the tag release on github - although I think they're the same).
The fix by @razius at https://github.com/razius/matplotlib/commit/66ee42d194bef1d045918c54cc81a9cb186bd440 works for me and I managed to install matplotlib from source after applying the same patch to
setupext.pybenesch commentedon May 28, 2014
@kmike agreed, this looks like it's fixed by #2623.
@steko @kravietz @espdev does installing from the 1.3.x branch work?
If so, @tacaswell I renew my request for a 1.3.2.
benesch commentedon May 28, 2014
Never mind; upon further investigation, this is unrelated to #2623.
This bug only occurs if pkg-config is not installed; a simple
will shore up the include paths for now.
tacaswell commentedon May 29, 2014
Closing this as #3067 is merged into master.
@benesch The issue with 1.3.2 is devs having enough time to produce one. As you can see we are swamped trying to get 1.4.0 out.
