[matplotlib-devel] Freetype config recommendation for installing matplotlib from Source

[Jim P. <jim...@gm...>]

All,
  I needed to install matplotlib from source along with all dependencies,
and I found a "gotcha" related to how setupext.py discovers freetype2
dependencies.

The default is to use
freetype-config --version

which uses a custom binary provided by freetype to list the version number
and linker dependencies.  Versions 2.4 and 2.5 of freetype use pkg-config
to also provide this information but matplotlib skips it.

setting
PKG_CONFIG_PATH=<path-to-custom-dependency>

or using setup.cfg

basedirlist=<path-to-custom-dependency>

will not fix the problem if your PATH variable points to the
freetype-config binary in your system path first.

If freetype-config is no longer necessary for matplotlib to compile, I
would recommend using  pkg-config to get the linker and compiler flags, so
that typical end-user fixes to paths will work as desired.

BTW, a clean install of freetype.2.5.2 will not compile with matplotlib
without including a soft link
ln -s <include-dir>/freetype2 <include-dir>/freetype

I think this a problem with the freetype package.  They have references to
changes in the structure of their includes in version 2.5.1.

Cheers,
--Jim

What version of matplotlib are you using?  The present behavior is 
(supposed to) only use freetype-config if pkg-config isn't available on 
the path.

Michael,
  I'm using matplotlib-1.3.1, and as mentioned above I manually set
PKG_CONFIG_PATH prior to running to ensure the dependencies are found.

The initial output from the matplotlib build shows that it is finding the
2.5.2 version
i.e. output from
python setup.py build is

freetype: yes [version 17.1.11]

Cheers,
--Jim
