qt

I need a site were I can learn qt. If anyone knows of one please post.

I figured out a command to compile but when I goto compile it gives me this.

g++ main.cpp -I /usr/include/freetype2 -I /usr/lib/qt3-gcc2.96/include -I /usr/X11R6/include -I /usr/lib/qt3-gcc2.96/mkspecs/linux-g++ -L /usr/X11R6/lib -L /usr/lib/qt3-gcc2.96/lib -I .moc/release-mt/ -lqt-mt -lpthread -lGLU -lGL -lXmu -lICE -lSM -ldl -lXext -lX11 -lm -lXinerama -lXrender -lXft -lfreetype -lcups -lmng -ljpeg -lpng -lz
/tmp/ccDPwaJW.o: In function `main':
/tmp/ccDPwaJW.o(.text+0x77): undefined reference to `GLObjectWindow::GLObjectWindow(QWidget *, char const *)'
/tmp/ccDPwaJW.o(.text+0xe6): undefined reference to `GLObjectWindow::~GLObjectWindow(void)'
/tmp/ccDPwaJW.o(.text+0x115): undefined reference to `GLObjectWindow::~GLObjectWindow(void)'
collect2: ld returned 1 exit status

Any suggestions?

Thanks,
