Problems installing matplotlib - compiling error

Community matplotlib-users

Hi guy,

as I'm new to matplotlib I tried to install it following the instructions on
http://matplotlib.org/faq/installing_faq.html#source-install-from-git
<http://matplotlib.org/faq/installing_faq.html#source-install-from-git> .
After downloading and changing the directory properly I get the following
error:

building 'matplotlib.ft2font' extension
gcc -pthread -DNDEBUG -g -fwrapv -O2 -Wall -D_FORTIFY_SOURCE=2 -g
-fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security

./CXX/WrapPython.h:58:20: fatal error: Python.h: No such file or directory
compilation terminated.
error: command 'gcc' failed with exit status 1

I'm using Linux Mint Nadia 14.2 Kernel 3.5.0.17, Python 3.2.3 (Oct 19 2012)
and gcc 4.7.2. Numpy, Simpy & Scipy are up to date.

What did I do wrong?
I have to use python3 because every other task was written specifficly with
python3.

cheers,
Christian

This error leads me to think that you need the Python3 development headers.
$ sudo apt-get install python3-dev # from memory, so yeah

Let us know if that works.

Thanks, that helped a lot! I don't know why the dev-package hasn't been
installed. That has been the first think I thought I did when re-installing
after my latest hardware change in December.

Thanks a lot. That saved my day.

As a shortcut, you can also install all of the build dependencies for a package (without installing the package itself) using:

    sudo apt-get build_dep python-matplotlib

small typo fix: the option name is 'build-dep'.

Cheers,

Hi,

yeah, during my system re-install I used the built-dep option
but maybe I was to busy to notice that I forgot the p3-dev’s. Now everything is running fine and the last two hours were enlighting.
