I'm trying to debug a simple program using gdb on SuSE 9.2 64bit stock (up to date on all patches), and I get an error when trying to debug the code in gdb:

I'm writing a simple Qt application, which compiles fine and exits cleanly. I don't want to publish the code just yet, so can't include it here unfortunately. But the code itself doesn't seem to be the problem anyway.
This are sample compilation commands (generated by qmake): # same for all objects: g++ -c -pipe -O2 -fmessage-length=0 -Wall -Wall -W -g -DQT_SHARED -DQT_TABLET_SUPPORT -DQT_NO_DEBUG -DQT_THREAD_SUPPORT -I/usr/lib/qt3/mkspecs/default -I. -I/usr/include -I/usr/lib/qt3/include -I.ui/ -I. -I.moc/ -o .obj/mycode.o mycode.cpp
# the linking step: g++ -o myprog .obj/mycode.o .obj/main.o .obj/mydialog.o .obj/moc_mydialog.o -L/usr/lib64/ -L/usr/lib/qt3/lib64/ -L/usr/X11R6/lib64/ -lqt-mt -lXext -lX11 -lm
Anyone knows what the problem is here?
Stupid questions: What happens if you do "list main" ? How about "list myfunc" where myfunc is something you know you wrote? What does -DQT_NO_DEBUG do to the -g flag?
