[Matplotlib-users] font problem on Mac OS X with GUI

[Michael O. <mic...@tu...>]

I have just installed the latest CVS version of matplotlib. The EPS/PS=20=

backend works
well with latex commands and also the png backend, but the GUI does not=20=

work anymore.
When I ran any of the examples in the examples directory I get the=20
message

** (simple_plot.py:5668): WARNING **: Cannot open font file for font=20
Verdana 10

** (simple_plot.py:5668): WARNING **: Cannot open fallback font,=20
nothing to do

and python terminates. I have set the TTFPATH environment variable and=20=

I have
added the correct font path in font_manager.py which didn't help.
After severe problems with the gtk and pygtk installation via fink I=20
decided to do a manual
installation by hand and everything compiled without any problems.

Thanks in advance for any help

Hi Michael,

Sorry for the delay in getting back to you.  

I don't believe this error message is coming from matplotlib itself.
Rather, I think it's coming from your GUI.  If you GUI is trying to
load a font, that almost certainly means you are not using one of the
*Agg backends: TkAgg, GTKAgg or WXAgg.  Which backend are you trying
to use?  From your message I assume GTK.  If GTKAgg is an option for
you, this will likely cure your problem.

However, we would like to sort this out for plain vanilla GTK as well.
Here are a thread that might have some relevant information for you -
