Description Alexander Stohr 2003-01-29 09:11:59 EST
Description of problem:
qt2 libary is built against gcc 2.96,
which means that it is not made with the
supplied compiler that is gcc 3.2 -
thus the libary is incompatible 
due to the changed c++ name mangling
between those two compiler versions.

Version-Release number of selected component (if applicable):
qt2, gcc 2.96 & gcc 3.2

How reproducible:
compile a qt based cpp program against qt2 library.

Steps to Reproduce:
Actual results:
massive list of unresolved symbols on linking stage

Expected results:
program should link against the provided librarys.
the librarys are considered to be an "alien" to the system.

Additional info:
i assmue this is caused by a broken SRPM that nobody has
noticed until now.

i do suggest those symlink sheme for /usr/lib location

  qt2 -> qt2-gcc3.2
  qt2-gcc3.2 -> qt-<qt2-version>-gcc3.2

  qt3 -> qt3-gcc3.2
  qt3-gcc3.2 -> qt-<qt3-version>-gcc3.2

and a similar sheme for any gcc 2.96 compiled libraries.
(in an environment with multiple compilers it is highly
important to have a smoothly ordered system of qt-libs.)

Hmm, qt2 is just a compat library, which is needed to run old qt applications
from 7.3. You have to use qt 3 if you want to build your qt applications with gcc3.2
