Link to Python with MinGW

With nm and dlltool from binutils, you should be able to rebuild the library for gcc:

echo EXPORTS > python32.def
nm python32.lib | grep " T _" | sed "s/.* T _//" >> python32.def
dlltool --input-def python32.def --dllname python32 --output-lib libpython32.a

python_test.c:

#include "Python.h"

int main(int argc, char *argv[]) {
    Py_Initialize();
    PyRun_SimpleString("from time import time,ctime\n"
                       "print('Today is',ctime(time())\n)");
    Py_Finalize();
    return 0;
}

Compile:

gcc -Wall -IC:\Python32\include -LC:\Python32\libs -o python_test.exe python_test.c -lpython32

Test:

C:\python_test.exe

Edit: If you’d prefer to skip building this yourself on x64, you can download it for several versions from Christoph Gohlke’s Unofficial Windows Binaries for Python Extension Packages.

Edit: Here’s a Python version based on the existing function that’s distributed in Tools/msi/msi.py:

import subprocess
import warnings
import re

NM = 'x86_64-w64-mingw32-nm'
DLLTOOL = 'x86_64-w64-mingw32-dlltool'
EXPORT_PATTERN = r'^[_]{1,2}imp_(?P<export>.*) in python\d+\.dll'

def build_libpython(ver, nm=NM, dlltool=DLLTOOL,
                    export_pattern=EXPORT_PATTERN):
    pylib = 'python%s.lib' % ver
    pydef="python%s.def" % ver
    pydll="python%s.dll" % ver
    libpy = 'libpython%s.a' % ver
    warning = '%s failed - ' + '%s not built' % libpy
    match_export = re.compile(export_pattern).match
    cmd_nm = [nm, '-Cs', pylib]
    cmd_dlltool = [dlltool, 
                   '--dllname', pydll, 
                   '--def', pydef,
                   '--output-lib', libpy]
    with open(pydef, 'w') as f:
        f.write('LIBRARY %s\nEXPORTS\n' % pydll)
        p_nm = subprocess.Popen(cmd_nm, 
                                stdout=subprocess.PIPE,
                                universal_newlines=True)
        for line in sorted(p_nm.stdout):
            m = match_export(line)
            if m:
                f.write(m.group('export') + '\n')
        if p_nm.wait() != 0:
            warnings.warn(warning % nm)
            return False
    if subprocess.call(cmd_dlltool) != 0:
        warnings.warn(warning % dlltool)
        return False
    return True

For example:

import os
for n in (27, 33, 35):
    pylib = 'python%s.lib' % n
    if os.path.exists(pylib):
        build_libpython(n)
        pydef="python%s.def" % n            
        lc_def = sum(1 for line in open(pydef))
        libpy = 'libpython%s.a' % n
        lc_lib = sum(1 for line in os.popen('ar -t %s' % libpy))
        assert lc_def == lc_lib
