使用swig将c ++编译为python

Question

I'm trying to compile very simple file to python on windows and I'm having a bad time.

The .i file is testfile.i:

%module testfile

%include "stl.i"

%{  
    int get_num() {
        return 3;
    }
%}  

int get_num() {
        return 3;
}

The swig function: {swig path}\\swig.exe -c++ -python testfile.i

This works perfectly, I now got the testfile.py file and testfile_wrap.cxx file. Now I understood that I need to compile this to library (.pyd on windows). I tried:

{gcc path}\\gcc.exe -fPIC -shared testfile_wrap.cxx -o testfile_wrap.pyd -L. -LC:\\Python27\\libs\\ -lpython27 -IC:\\python27\\include.

Here is the problem, I get alot of errors like this ones:

C:\Users\itay\AppData\Local\Temp\ccANsNeU.o:testfile_wrap.cxx:(.text+0xc00): undefined reference to `__imp_PyExc_MemoryError'
C:\Users\itay\AppData\Local\Temp\ccANsNeU.o:testfile_wrap.cxx:(.text+0xc13): undefined reference to `__imp_PyExc_IOError'
C:\Users\itay\AppData\Local\Temp\ccANsNeU.o:testfile_wrap.cxx:(.text+0xc26): undefined reference to `__imp_PyExc_RuntimeError'
C:\Users\itay\AppData\Local\Temp\ccANsNeU.o:testfile_wrap.cxx:(.text+0xc39): undefined reference to `__imp_PyExc_IndexError'

And it continues on and on.

What am I doing wrong?

Thank you for your help

Update: I managed to call swig and compile/link using visual studio 2013 but I get the same error. I followed tutorials and it still does not work.

The solution: my python was 64 bit and it didn't work. Changed to python 32 bit and now it is working (python 2.7.10)
