Re: [Matplotlib-users] installing matplotlib on ubuntu

[Ryan K. <rya...@gm...>]

I know this can be frustrating, but hang in there.

Your initial error about pygtk.h not being found is a dependency
error.  You need some other packages and I am not sure what they all
are. They are generally the development packages.  For this one,
search in the Synaptics package manager for pygtk and find
python-gtk2-dev (and probably python-gnome2-dev).  You may run into a
few more of these.  Whenever you see a *.h: No such file error, you
have a dev package missing.

The only way around the wx-config error is to download the wxPython
source tarball and find wxPython.h.  Then copy it to
/usr/include/wx/wxPython/wxPython.h.   I will attach mine, but this
may be a bad idea.  You can download from their webpage here:
http://www.wxpython.org/download.php#sources
(grab the first one in the list that doesn't say RPM - it is the tar.gz fil=
e).

So, copying wxPython.h from the tarball or the attached file should
solve the wx-config error (you may need the other *.h files in the
same folder of the tarball). Working through the dev packages should
solve the errors with the other backends.  I have TkAgg, GTKAgg,
WXAgg, and PS working on mine (there are probably others, but those I
have tested).

Let me know if you need more info.
