They are defined in the python dylib, but they are also defined in the /sw/bin/python2.4 executable. > isn't it safer to this on the link command ? I am no expert in loadable modules vs dylibs, but I suspect that the python modules are loaded via dlopen & friends rather than dyld, and that they get their undefined symbols from the python executable. One could perhaps even use the -bundle_loader %p/bin/pythonX.X flag. But the python modules that I have seen all use -undefined dynamic_lookup. The sip package does this too, BTW. There is another thing that worries me about the sip/pyqt combination: In the installed q*mod.sip files, there are a lot of lines QMAKE_LFLAGS += -framework Python AFAICT they come from the decision to use the macx-g++ specs file in the sip package and to modify it only as far as necessary to build sip itself with Fink's python. One would need to test whether the packages not only build OK, but also *work*. I could imagine that it becomes necessary to use the darwin-g++ spec file for sip instead of macx-g++, so that the Python framework is completely eradicated from the sources used. -- Martin ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
