[Py2exe-users] Problems with matplotlib/mathtext fonts

[Jonno <jon...@gm...>]

My wx app works on my pc but crashed when I export it to a "clean" pc.

I am seeing the following warnings in app.exe.log:

And I also see a traceback which ends with:
File "matplotlib\mathtext.pyo", line 720, in _get_glyph
KeyError: 98

The fonts that can't be found are all used by matplotlib/mathtext.

I then discovered that both the methods I tried for getting data_files
(using glob and matplotlib.get_py2exe_datafiles) were not working and
nothing was getting copied to my mpl-data/fonts directory. The source
directory: C:\Python27\Lib\site-packages\matplotlib\mpl-data\fonts contains
3 folders: afm, pdfcorefonts & ttf. The ttf folder is where the mathtext
fonts mentioned above are located.

I tried manually copying the entire mpl-data folder into the dist folder
after running py2exe on setup.py but still I get the same error.

Does data_files do anything other than include files and directories in the
dist folder?
It seems that the findfont method in matplotlib's font_manager isn't
working after running through py2exe and I guess when _get_glyph in
mathtext.pyo attempts to use Bitstream Vera Sans font.

Any ideas anyone?
