Hello,

When I wanted to compile wxPythonSrc-2.4.1.2 from source on my ibook (mac os 10.2.6, 384 MB RAM, 600 MHz G3, MacPython 2.3), it failed:
% python setup.py build

does anybody have a hint on how I could compile the wxPython?

Thanks a lot,

Hmmm... I've seen this when building glcanvas, not gdi, but it is the same problem so the same solution should fix it. Just add something like this in the files that have the problem, after helpers.h or wxPython.h are #include'ed:

#ifdef __WXMAC__ // avoid a bug in Carbon headers
#define scalb scalbn
#endif
