I am in an openGL class. The examples that the teacher provides are compiling on the university schools systems. The won't on my new fedora install (the university also uses fedora).

Basically I think that there are different GL libs installed???

when i type make lines (to make lines.c) it outputs this info:
gcc -O -Wall -g -gstabs -I/usr/include/GL -L/usr/lib -L/usr/X11R6/lib -lglut -lGLU -lGL -lXmu -lXi -lXext -lX11 -lm -o lines lines.c
/usr/bin/ld: cannot find -lglut
collect2: ld returned 1 exit status
make: *** [lines] Error 1

So I think there is a problem with the -lglut param. I have freeglut.h in /usr/include/GL, but no flut.h.

That can I get do to get this to comiple?

Here is a dir with the makefile and some c files that should comiple (I have seen them compile in class)

Thanks for any help

the compiler can't find the library of glut
try to look for a file called
libglut.a and when you find it add the following flag to the compiler before the -lglut:
-LPATH
for example if the file is at /etc/somedir
the write -L/etc/somedir
this will tell the compiler to look for the library there.
if that doesn't work or if you don't have that file, try reinstalling the openGL development library.

You're sure that I need libglut.a (caps). Locate does not find it. I did updatedb just to be sure. How can I reinstall the library/package? I am new at linux. I appreciate your help.

glut doesn't always come with Linux distributions. freeglut is a different animal from glut, I believe. I've never used freeglut, but from what I recall of it, it is basically a glut-like library with some of the problems of glut being fixed.

If you are using that, the library is likely named something else, so you can change -lglut to -lfreeglut or whatever the freeglut library is named. Otherwise, check here for a place to download glut from.
