SWIG Python undefined reference

[Soren]

Hi,

I went through the SWIG tutorial for the example named "simple".

I managed to get to the first step, creating example_wrap.c using
swig, and doing:
"gcc -fpic -c example_wrap.c -IC:\python24\include " to create
example_wrap.o

But when I needed to compile the library file using:
"gcc -shared example_wrap.o -o examplemodule.so" I received a lot of
undefined reference compiler errors like:

example_wrap.o(.text+0x35a5):example_wrap.c: undefined reference to
`_imp__PyErr
_SetString'

there are many other similar errors all prefaced with _imp__Py, so I
am assuming there is a linker error with the python libraries. I have
adjusted my PATH variable to include all the python directories (libs/
dlls).

Does anyone here have any suggestions?

FILES FROM TUTORIAL:


//example.c
#include <time.h>
double My_variable = 3.0;

int fact(int n) {
if (n <= 1) return 1;
else return n*fact(n-1);
}

int my_mod(int x, int y) {
return (x%y);
}

char *get_time()
{
time_t ltime;
time(&ltime);
return ctime(&ltime);
}
