[Pythonmac-SIG] Embedded Python compiling help

[Michael Gaiman]

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
