Thanks for your help, Bob.

The gcc command it had me gave me is

gcc -o runfunc run-func.c -fno-strict-aliasing -Wno-long-double
-no-cpp-precomp -mno-fused-madd -fno-common -dynamic -DNDEBUG -g -O3
-Wall -Wstrict-prototypes -I.
-I/private/var/tmp/python/python-7.obj~4/python/Include
-DPy_BUILD_CORE
-I/System/Library/Frameworks/Python.framework/Versions/2.3/include/ python2.3

which produces the following output: ld: Undefined symbols: _PyCallable_Check _PyDict_GetItemString _PyErr_Occurred _PyErr_Print _PyImport_Import _PyInt_AsLong _PyInt_FromLong _PyModule_GetDict _PyObject_CallObject _PyString_FromString _PyTuple_New _PyTuple_SetItem _Py_Finalize _Py_Initialize

Sorry if I'm missing something super obvious, I've not really spend too
much time with gcc.

Thanks, Mike

I'm getting started embedding python for a school project. I am starting by getting the program listed in http://docs.python.org/ext/pure-embedding.html. The next step is compiling. I've tried quite a few gcc commands, but no dice. The latest command I've tried is gcc -I/System/Library/Frameworks/Python.framework/Versions/2.3/include/ python2.3 -L/System/Library/Frameworks/Python.framework/Versions/2.3/lib/ python2.3/config -o runfunc run-func.c which fails due to undefined symbols. If anybody could take a minute and list the correct gcc command to compile and link this program, I would be very grateful. I'm using MacOSX 10.3.6 with the built in python. gcc -o runfunc run-func.c python -c "import_ _distutils.sysconfig;print_ _distutils.sysconfig.getconfigvar('PYCFLAGS')" er.. that's not it, but it's close.. you probably also need the output of print '-I' + distutils.sysconfig.getconfigvar('INCLUDEPY') -bob
