Description John Ellson 2010-08-25 16:29:34 UTC 
Description of problem:
SWIG generated code that has been working for years now breaks on Fedora-14, I think probably because of swig not tracking the python-2.7 upgrade.

Version-Release number of selected component (if applicable):
swig-2.0.0-4.fc14.x86_64
python-devel-2.7-8.fc14.x86_64
graphviz-devel-2.26.0-4.fc14.x86_64
gcc-4.5.1-1.fc14.x86_64

How reproducible:
100%


Steps to Reproduce:
1.swig -c++ -python -o gv_python.cpp /usr/include/graphviz/gv.i
2./usr/bin/g++  -I/usr/include/python2.7 -I/usr/include/graphviz  -c -o gv_python.o gv_python.cpp
  
Actual results:
gv_python.cpp: In function ‘void SWIG_Python_DestroyModule(void*)’:
gv_python.cpp:2511:70: error: invalid conversion from ‘void*’ to ‘PyObject*’
gv_python.cpp:2511:70: error:   initializing argument 1 of ‘void* PyCapsule_GetPointer(PyObject*, const char*)’
gv_python.cpp: In function ‘void SWIG_Python_SetModule(swig_module_info*)’:
gv_python.cpp:2539:34: error: invalid conversion from ‘void (*)(void*)’ to ‘void (*)(PyObject*)’
gv_python.cpp:2539:34: error:   initializing argument 3 of ‘PyObject* PyCapsule_New(void*, const char*, void (*)(PyObj

Expected results:
no compile errors.

Additional info:
On fedora-13, the same test but with-I/usr/include/python2.6 works without error.
