[PyKDE] Problems installing and compiling PyQt on Redhat 7

[Gerard Vermeulen]

Boudewijn,

I am not a Red Hat user (anymore), but maybe I can help:

(1) Since there is an include flag -I/usr/local/include/python2.0,
I conclude that this is not a standard RedHat package.
Check out if they have a python-2.0*.rpm

(2) Look at http://www.python.org/cgi-bin/moinmoin/FrequentlyAskedQuestions
There is help on Red Hat 7.0 compiler issues (you also need to upgrade glibc).

(3) This is normal because Red Hat's compiler has a different binary C++ api,
so you can't mix Mandrake-7.2 and Red Hat-7.0 C++ libraries.
