installing SWIG for python

[Jerry He]

Hi,
I just installed SWIG on Windows(Cygwin) and tried
to use it to compile some of the example python
programs.

For the first two commands it produced no error
swig -python example.i
gcc -c example.c example_wrap.c -I \
/usr/include/python2.4

For the third one however
ld -shared example.o example_wrap.o -o _example.so

It gave me a long list of errors listed at the end of
this email.

The error messages were rather baffling because the C
file that was to be made into a python Module was a
simple gcd function, it doesn't need strlen, or any of
the other C functions, and much less Tcl_Append, what
does this have to do with Tcl?

Any help or suggestions on this would be
appreciated...
