Problem compiling matplotlib from master

Development matplotlib-devel
1

Hello,

Since I’ve updated my master branch, I have a new error when installing matplotlib. It seems it doesn’t find a header file from numpy:

I’ve reinstalled numpy (development version), and I tried to reinstall everything (on python 2.6) but I still get the error. Am I the only one having installation problems ?

Here is the (partial) traceback:

It thinks the Numpy header files are here:

/usr/lib/pymodules/python2.6/numpy/core/include

are they there and from the right version of Numpy?

When you run python (the same copy you're building with), and import numpy and print "numpy.__version__" does that give the expected version. What does "numpy.__file__" and "numpy.get_version()" give?

That's weird. Did you try installing a stable numpy version instead?
I tried compiling mpl against numpy 1.6.2 and everything worked out
fine.

I tried compiling mpl against numpy 1.6.2 and everything worked out
fine.

I'm reinstalled everything, and it works fine. I still have problems when I
switch from an old branch (before the merge of the packaging changes) and
master, but I've resigned myself to destroy my virtualenv each time.

Thanks for the inputs !

I often find that a `git clean -fxd` is enough, rather than blitzing my whole virtualenv.
