[matplotlib-devel] Getting TkAgg backend to work on OS X

[Kenneth M. <kmm...@wi...>]

I believe this is the right list, since the question deals with
compiling, rather than using, matplotlib.  Hope that's OK.

I just dl'ed, and after setting the TkAgg flag to 1 in setup.py,
did a python setup.py install. (Note that I had done
a previous install without the TkAgg flag set.) On my system,
this is producing a bunch of errors related to the Tk headers:

...

...

and so on, for a very long time.

I have done some messing around with Tk--I'm currently running  
AquaTcl/Tk, not the
X11 version--but don't have a good handle on how to deal with the  
above. Any
ideas? I'd really like to start using matplotlib!

Thanks,
