Hi, Actually i see the same error message using python2.5 when building ITK python wrapping.
I was wondering what i am doing wrong that ld is not seeing pytohn properly to find those symbols? Any one know what is going wrong to give error message like >> /usr/bin/ld: Undefined symbols: >> _main >> _PyArg_ParseTuple >> _PyInt_FromLong >> _PyString_FromString >> _PyTuple_New >> _PyTuple_SetItem >> _Py_InitModule4 >> collect2: ld returned 1 exit status which lib or headers or something is ld not seeing? cheers Dan On 14 Dec 2006, at 13:00, [EMAIL PROTECTED] wrote: > From: "Bob Ippolito" <[EMAIL PROTECTED]> > Date: 14 December 2006 12:28:29 GMT+02:00 > To: "Gen Kazama" <[EMAIL PROTECTED]> > Cc: pythonmac-sig@python.org > Subject: Re: [Pythonmac-SIG] CPython on Mac OSX > > > On 12/13/06, Gen Kazama <[EMAIL PROTECTED]> wrote: >> Hi I'm running python 2.3 on 10.4. i made an application using a >> C backend >> and a python frontend. >> >> This is a school project and although it works perfectly on the >> school >> computers, i have trouble compiling the C code correctly on the >> mac to make >> it into a python module (maybe this is because the school >> computers used >> python 2.4-ie, an updated version of Python.h). >> >> Anyway here is how I compile it at school: >> >> gcc -I /usr/include/python2.4 -c mandel.c >> gcc -shared mandel.o -o mandel.so >> >> which works with no flaws. then , I try compiling it on my mac: >> >> gcc -I /usr/include/python2.3 -c mandel.c >> gcc mandel.o -o mandel.so >> >> (note: -shared wasn't found on my mac for some reason).
