2008/4/9 Kyle Simpson <kyle.simpson at gmail.com>: > Any other ideas on this topic? As I said before, the problem is that you are managing to either install mod_python.so into the wrong installation or you have compiled it against the header files for the wrong version of Apache. The proof of this is that the magic number your mod_python.so has equates to: #define MODULE_MAGIC_COOKIE 0x41503230UL /* "AP20" */ whereas Apache is expecting: #define MODULE_MAGIC_COOKIE 0x41503232UL /* "AP22" */ Do you have header files installed in the following directory? /usr/local/apache28/include Are those header files readable to the user that you are compiling mod_python? Look in the header file 'ap_mmn.h' in that directory, what is the value of MODULE_MAGIC_COOKIE? Now go find where the header files for your other Apache installation are located and find what its value of MODULE_MAGIC_COOKIE is? What directory are those header files in? To work out why it is picking up wrong header files, as I suggested before, look at the -I flags used when compiler is run on mod_python source code. For example on my system I get: /usr/local/apache-2.2.4/bin/apxs -I/Users/grahamd/Projects/mod_python-trunk/src/include -I/System/Library/Frameworks/Python.framework/Versions/2.3/include/python2.3 -DNDEBUG -Wc,'-arch ppc' -c mod_python.c _apachemodule.c requestobject.c tableobject.c util.c serverobject.c connobject.c filterobject.c hlist.c hlistobject.c finfoobject.c -arch ppc -Wl,-F/System/Library/Frameworks -framework Python -u __dummy -u _PyMac_Error -framework System -framework CoreServices -framework Foundation -ldl What do you get?
