[matplotlib-devel] Some notes on building from CVS

[Daishi H. <da...@eg...>]

Hi,

I just built matplotlib from CVS on debian/linux and mac os x,
and had to modify some things. I thought the information might
be useful to others, and that people on this list might advise me
if there were better fixes.

On debian, I had to make the following modification to setupext.py:

-       o.tcl_inc = os.path.join((tk.getvar('tcl_library')), 
'../../include')
         o.tk_lib = os.path.join((tk.getvar('tk_library')), '../')
         o.tkv = str(Tkinter.TkVersion)[:3]
       return o

I'm using a fairly mixed stable/testing/unstable version of debian, so
maybe that's the reason for my needing to make this change.

On mac os x, I was going to use fink for the dependencies, and so
I modified setupext.py as follows:

Do most of the users of matplotlib on os x not use fink? The stumper
for me is that I have been unable to build scipy/numpy for the python
that is bundled with os x - has anyone been successful with this?
(is this process documented anywhere?)

For both debian and os x, I found that I would get the following error:

---
   File 
"...../lib/python2.3/site-packages/matplotlib/backends/backend_wx.py", 
line 611, in get_wx_font
     self.fontweights[t.get_fontweight()], # Weight
KeyError

where t.get_fontweight() seems to be returning None. I "fixed" this by
adding

but there is probably a better/cleaner way to solve this problem...
