[Matplotlib-users] Re: Bus error on Mac OS 10.3.9

Hi folks,

I'm just checking in with the solution to my Panther bus error
issue, in case it might help someone else, but also to publicly
thank John for walking me through the diagnosis.

It turns out the problem was due to using an old version of gcc.
The owner of the PowerBook I was installing mpl on hadn't
installed Apple's gcc updaters.  He had gcc 3.3, but not Apple's
most recent build, which fixes some C++ issues.  As a result,
C and Fortran extensions built fine, but C++ extensions built
with pycxx resulted in bus errors.  For example, "import pylab"
produced a bus error, but 

>>> import matplotlib.backends._tkagg
>>> import matplotlib.agg

produced no errors, because these extensions are not built
with pycxx.  A rebuild after updating gcc led to a working mpl.

John figured this out from the pattern of which modules loaded
and which led to errors.  I never would've figured it out on
my own.

numpy and scipy both installed fine with the older gcc and passed
all tests.  I wonder if they should be reinstalled.  If anyone
knows about this, please let me know.  The owner is uncomfortable
installing things from source, and I only have infrequent contact
with him, so if these need fixing I'd like to do it soon.

Cheers,
Tom
