Matplotlib Build Problem: Error C1083: Cannot open include file: 'ft2build.h'

Question

ft2build.h is located here:

C:\Program Files\GnuWin32\include

Initially, I made the same mistake as here:

Fatal Error C1083: Cannot Open Include file: 'tiffio.h': No such file or directory VC++ 2008

but since then, I've corrected that particular error (I've added the above directory to the "include" list, rather than the "executables" list), but I still get an error. The complete output is this:

I should mention that this is Python 2.6

Answer 1

This error comes about when building matplotlib on Ubuntu 10.10 also. The solution is to do:

sudo apt-get install python-dev libfreetype6-dev
