[Gdal-dev] Python Module Build

[Sean Fulton]

For GDAL 1.2.0 Python linking fails on OS X as usual with:

g++ -Wl,-bind_at_load  -o .libs/_gdalmodule.so -bundle  
.libs/gdal_wrap.o .libs/numpydataset.o .libs/gdalnumeric.o  
-L/opt/local/lib /opt/local/lib/libdl.dylib 
/opt/local/lib/libjpeg.dylib ../.libs/libgdal.dylib
ld: Undefined symbols:
_PyArg_Parse
_PyArg_ParseTuple
_PyDict_New
...

I've found that running the above command with "-framework Python" 
fixes this error, however, I can't find how to add "-framework Python" 
to that build command through the make or autoconf files.

The configure log shows a PYTHON_LINK variable whose value contains 
"-framework ${PYTHONFRAMEWORK}" but it doesn't seem to be used 
anywhere.

How do I pass "-framework Python" to the build command?

Also, is there a way to specify more than one location for Python 
headers and libs without mucking about in the configure script? Setting 
the PYTHON_INCLUDE environment variable seems to have no effect on 
configure.


Thanks.
