Description
Having trouble building matplotlib from source. It seems that QHULL_LIB_CHECK is not defined for me, which causes a chain of useless errors. My guess is that the problem is I already have a system Qhull package (for ROS), which is conflicting with the bundled one. Here's the output I get:
python setup.py build

In case it's relevant, here's some info about my installed qhull
dpkg -s libqhull-dev
Package: libqhull-dev
Status: install ok installed
Priority: optional
Section: libdevel
Installed-Size: 1092
Maintainer: Ubuntu Developers <ubuntu-devel-discuss@lists.ubuntu.com>
Architecture: amd64
Multi-Arch: same
Source: qhull
Version: 2012.1-4
Depends: libqhull6 (= 2012.1-4)
Description: calculate convex hulls and related structures (development files)
Qhull computes convex hulls, Delaunay triangulations, halfspace
intersections about a point, Voronoi diagrams, furthest-site
Delaunay triangulations, and furthest-site Voronoi diagrams. It
runs in 2-d, 3-d, 4-d, and higher dimensions.
.
This package contains the files necessary for development (headers and
libraries), as well as the library documentation in HTML format.
