Re: [matplotlib-devel] Re: Problem building CVS version on OS X

[Andrew S. <str...@as...>]

Hmm... I've tested with gcc 3.3 on linux, so I'm not sure why it's breaking.

First, check if adding "#include <math.h>" will help.

Some other ideas:
 * Do "man isnan" from the command line and see if it specifies another
header file.
 * Search inside /usr/include for isnan and see what comes up.

Good luck,
Andrew
