[Matplotlib-users] Bug in WXAgg on OS X and Matplotlib 0.87
|
From: Samuel M. S. <sm...@sa...> - 2006-02-25 17:23:05

Setting the WX_CONFIG environment variable before the build fixed one
problem. It is now finding my matplotlibrc file.
I thought maybe it was a font corruption problem but it I use TkAgg
everything works fine with my 0.87.1cvs build. So
I think maybe I have uncovered a bug in the WXAgg? I would like to
help fix it but I don't have a clue of where to start.
I also tried WxAgg with the first fonts in the rc file set to the
ones that come installed with matplotlib
font.serif : Bitstream Vera Serif
font.sans-serif : Bitstream Vera Sans
and it still crashes. So something is wrong. Maybe its my
environment. It would be nice if someone could verify
if they get the same problem
Here is the debug output
