Hi, I have a possibly stupid question -- my apologies. I am trying to build some modules written on a Linux platform in Windows (Windows 2000) using mingw32. I have tried building the following REALLY basic module and am getting some strange errors (it works fine with VC++ 6.0). My command line is python setup.py build -c mingw32 Module: #include <Python.h> static PyObject *myfoo(PyObject *self, PyObject *args, PyObject *keywords); /* Module methods */ static PyMethodDef FooMethods[] = { {"_myfoo", (PyCFunction) myfoo, METH_VARARGS|METH_KEYWORDS, "FOO!"}, {NULL, NULL, 0, NULL} /* Sentinel */ }; /* Initialize the module foo */ void initfoo(void) { PyObject *module; module = Py_InitModule("foo", FooMethods); } static PyObject *myfoo(PyObject *self, PyObject *args, PyObject *keywords) { int output_int; char *keyword_list[] = {"output_int", NULL}; if (! PyArg_ParseTupleAndKeywords(args, keywords, "i", keyword_list, &output_int)) { PyErr_SetObject(PyExc_TypeError, Py_BuildValue("OO", args, keywords)); return NULL; } fprintf(stderr,"%d\n", output_int); return(Py_None); } Here is my setup.py file from distutils.core import setup, Extension import os libraries=[] library_dirs=[] include_dirs=[] mincutils_mod = [] mincutils_mod.append(Extension('foo', sources = ['foo.c'], include_dirs=include_dirs, library_dirs=library_dirs, libraries=libraries)) setup (name = 'foo', version = '0.4', description = 'This is a package to foo.', author = 'Jonathan E. Taylor', author_email = 'jonathan.taylor@stanford.edu', url = '', long_description = ''' ''', ext_modules = mincutils_mod) and the error messages: F:\Python Example>python setup.py build -c mingw32 running build running build_ext building 'foo' extension writing build\temp.win32-2.3\Release\foo.def F:\MinGW\bin\gcc.exe -mno-cygwin -shared -s build\temp.win32-2.3\Release\foo.o b uild\temp.win32-2.3\Release\foo.def -LF:\Python23\libs -LF:\Python23\PCBuild -lp ython23 -o build\lib.win32-2.3\foo.pyd build\temp.win32-2.3\Release\foo.o(.text+0x94):foo.c: undefined reference to `_i mp__PyExc_TypeError' build\temp.win32-2.3\Release\foo.o(.text+0xc1):foo.c: undefined reference to `_i mp___Py_NoneStruct' error: command 'gcc' failed with exit status 1 Any help would be greatly appreciated.
