Hi Sid,
I don't have GCC 4.3 yet. I'm running Fedora 8 and I'll be able to get
to the newer GCC when Fedora 9 will be released (pretty soon). The only
difference I could sort out is that I have -I/usr/lib/qt-3.3/include
instead of -I/usr/lib/qt3//include that gets passed to g++ during the
compilation. So may be you got the wrong version of Qt (it should be the
latest Qt3 release) or may be your Qt is badly configured. configure
gets both the include files path and the library path from a utility
called pkg-config. Try to run:
$ pkg-config --cflags qt-mt
from a shell. You should get something like:
-DQT_SHARED -DQT_TABLET_SUPPORT -DQT_NO_DEBUG -DQT_THREAD_SUPPORT
-D_REENTRANT -I/usr/lib/qt-3.3/include
Here is the output of my LiveCam build:
