opengl problem on ATI card

Hi All,
I have some opengl code that runs great, when I compile it on my laptop or works PC it compiles great. However on my new PC it reports a single opengl error. My new PC has ATI cataylst drivers, which according to manufacturer are correct. However when I run it I get the following error

Code:

/usr/bin/ld: /tmp/ccxGyjOs.o: undefined reference to symbol 'glNormal3f'
/usr/bin/ld: note: 'glNormal3f' is defined in DSO /usr/lib/libGL.so.1 so try adding it to the linker command line
/usr/lib/libGL.so.1: could not read symbols: Invalid operation
collect2: ld returned 1 exit status
make: *** [all] Error 1

As I said the code compiles on my laptop and desktop (both nvdia) but not my new PC (ati) so is there n issue with the ati driver, does anyone know a way round this?

Should add I do include in my libs GAME_LIBS = -lpthread `sdl-config --cflags --libs` -lSDL_mixer -lSDL_image -lSDL_ttf -lGLEW

Thanks

You're not linking against the GL library, and you clearly should be. Does /usr/lib/libGL.so exist? If not, link /usr/lib/libGL.so.1 to /usr/lib/libGL.so and "-lGL" to GAME_LIBS.

Hi thanks, just got that before you posted. But don't understand how lgl is not needed on the nvidia systems? Anyway it made no differnce to running as that gives a segmentation fault everytime its ran, then when I went to reboot my system it boots in text mode :s
