Just tried to build current master under ubuntu raring, but I get an error (dependencies are installed with sudo apt-get build-dep python-matplotlib before) from the gtk check:


$ python setup.py build

It doesn't help to set gtk = False and gtkagg = False in setup.cfg

In setup.cfg, are you putting gtk = False under the [gui_support] section, i.e.:

[gui_support]
gtk=False

For me, that works -- i.e. I can't reproduce the part of this bug where the gtk check isn't being turned off altogether.

As for the rest, this error message:

/usr/lib/python2.7/dist-packages/gi/overrides/Gtk.py:48: RuntimeWarning: You have imported the Gtk 2.0 module.

most likely indicates that you do not have the gtk3 development files installed. See this StackOverflow question:

http://stackoverflow.com/questions/11828995/why-my-gi-repository-gtk-keeps-using-gtk-2-modules

At matplotlib's end, we should probably specify that gobject introspection will only work with Gtk 3.0 and fail more gracefully if it can't be found. We still use the old pygtk interface for Gtk 2.0 (which still should work).

I copied setup.cfg.template to setup.cfg and then I changed gtk and gtkagg to False under the [gui_support] section. However the error occurs.

Installing libgtk3-dev solved the problem, I can build matplotlib now.

Good news. I see why the disabling didn't work for you now (and I mistyped in my earlier message). It's the gtk3 and gtk3agg extensions you would want to disable to avoid this (not gtk and gtkagg), but those are missing from the template file. I'll be sure to add those.

Thanks.

I have come across the same error (building 1.3.0 from source on Debian wheezy 64bit) and actually for me the respective backend checks are not skipped even if I copy setup.cfg.template to setup.cfg and set gtk3cairo and gtk3agg to False. I put a breakpoint in OptionalBackendPackage.get_config() and found that it actually doesn't get called at all for some of the backends (namely qt4agg, gtk3cairo, gtk3agg, wxagg, cairo and windowing). To me it looks like the overridden check() methods in the subclasses for these backends never look at the config. I excepted the error locally so for me this is not a problem, I just wanted to mention it. I'll open a pull request to fix this.
