Problem building Matplotlib 1.3.1 on linux (CentOS 5.9 AMD64)


I’m having an issue building Matplotlib. In reality the build process finishes without error, but afterwards I get this error when importing pyplot:

[kpi@…4473… lib.linux-x86_64-3.3]$ python3.3

Python 3.3.2 (default, Sep 17 2013, 10:40:41)

[GCC 4.4.7 20120313 (Red Hat 4.4.7-1)] on linux

I don’t know a thing about building C extensions, but if I understood correctly some pasts posts in this list and others, this problem might be caused by a library that is compiled with an incompatible version of GCC.

My first suspect was freetype, so I downloaded and compiled v2.4.12 using gcc44 (which is the same compiler I used to build python3.3 and matplotlib).

But the problem persists… My question is: how can I know wich library is causing the issue, so I could recompile it?

Or, if I am completely missing the root cause, thank you for steering me in the correct direction :slight_smile:

More detailed info follows. Thank you for your help !


Here is the information asked for in the troubleshooting FAQ:

But please, note that I am using a Python version built by myself (not the version that comes with CenOS 5.9) using gcc 4.4.7 (and not gcc 4.1.2)

Here is what I modified in setup.cfg last time (but I also tried with an unmodified version with the same results):


agg = True

cairo = False

gtk = False

gtk3agg = False

gtk3cairo = False

gtkagg = False

macosx = False

pyside = False

qt4agg = False

tkagg = False

windowing = False

wxagg = False


backend = Agg

I didn’t modify any other config file. Here is the output of the build process:
