hi,
i can't seem to compile my program under linux mandrake 7.0
gcc -o -L/usr/X11R6/lib -lGL -lGLU file.c
it says:
GL/gl.h : No directory or file found
GL/glu.h : No directory or file found
so how do i now if i have these file intall? if i do not have it, which *.rpm i need to intall from Mandrake linux 7.0?
thank you.
To see if the file is installed or not, try:
locate gl.h
If nothing comes back, you need to install XFree86-devel and Mesa-common-devel
Hope this helps.
hi i did locate gl.h and nothing comes back. so i reinstall XFree86-devel and Mesa-common-devel and it still says the same thing. GL/gl.h ad GL/glu.h : no suck directory or file.
manually i found the file gl.h and glu.h at /usr/X11R6/include/GL/ so why isn't it finding those files? do i need to specify something in the PATH? thanks.
In that case add -I/usr/X11R6/include to your command line to GCC.
Cheers.
hi,
ok. now when i type gcc -o -I/usr/X11R6/include/ -lGL -lGLU -lglut file.c it gave me the following error message:
/usr/bin/ld : cannot find -lGL
collect2: ld return exit status
so how do i fix this? thanks.
um...did you remove the -L... path that you had in your above post? and if you didn't, then locate where libGL<bla>.so/a libraries are and just give gcc -Lpathname to it...Originally posted by caophong:

or you might want to make a sym link to the gl directories from the well known include/lib directories.
good luck
I said "add", not "replace -L by -I".Originally posted by caophong:

gcc -o myprogram -I/usr/X11R6/include/ file.c -L/usr/X11R6/include -lGL -lGLU -lglut.
wooohoooo it works thank you. just have to change
gcc -o myprogram -I/usr/X11R6/include/ file.c -L/usr/X11R6/lib -lGL -lGLU -lglut.
