Hi, after having correctly compiled matplotlib, now is time to test
something (I need at least to get it something working before I can
start hack it autonomously =). Unfortunately, it's not usable: it
complains about not being able to load "_tkagg" module. The fact is I
don't want "tkagg" backend at all! Here is the backends dependencies
detect log:
OPTIONAL BACKEND DEPENDENCIES
libpng: found, but unknown version (no pkg-config)
Tkinter: no
* Tkinter present, but header files are not found.
* You may need to install development packages.
wxPython: no
* wxPython not found
Gtk+: gtk+: 2.10.11, glib: 2.12.11, pygtk: 2.10.6,
pygobject: 2.12.3
Qt: no
Qt4: no
Cairo: 1.2.6
As it should be clear, I want to use the a gtk+ aware backend, and
initially in fact I used a customized "setup.cfg"; seeing the error I
tryed deleting the customized "setup.cfg", but without results. Is
there some problems with backend selection on windows platform?
I hope gtk+ backends are supported. Follows 2 traces of the error
running an ipython shell and a test python program (it works on
linux).
Any help is appreciated.
Thanks,
Francesco
