Dear Alexandre,


I'm a SuSE 9.x user too: SuSE 9.2. I experience the same frustration. Working hard
this day, I figured that the gcc optimizations made by SuSE (I think) drop out
the 'extern "C" const' symbols. You need to use -O1 optimization:

export CXXFLAGS="-O1"
export CFLAGS="-O1"
./configure --with-qt-dir=/opt/qt/3.4 --with-sdl-prefix=/usr/local --with-win32-path=/usr/local/lib/win32


For Avifile developers. Please insert a note in INSTALL documentation to make SuSE >= 9.1 users
aware about gcc/g++ bad behaviour.
