matplotlib-devel Mailing List for matplotlib

I'm trying out the brand new python2.5b2.  One of the reasons I am =20
excited to upgrade is that ctypes are included in the new python, and =20=

this is pretty hard to get going by hand on the intel Macs because of =20=

an absent libffi.  I get

error: invalid conversion from =91const char*=92 to =91char=92

when trying to compile matplotlib on my intel Mac with python 2.5b2.  =20=

I don't get a similar error with python 2.4.x.  The full output is =20
attached below.  I tried to recompile agg.cxx with swig (recompiled =20
to link with python 2.5b2) using this command

python makeswig.py

and I get the same error.  BTW, numpy compiles without any =20
complaints, and seems to work just fine.  Any ideas?
