Just check whether you have the code correct or not, as i can run it
perfectly here, i tried the code out from the links you gave, i tried
the spinning cube one, and also check whether you have correct header
files and packages.*From the program i can say that freeglut is missing,
some of the API's used use some functions of freeglut *. If you still
couldn't get it right, mail me the code you are using, verbatim.And
there is no need of doing -lm -lGL -lGLU , only lglut will do for the
spinning cube program.Btw I am a student of CS 6th sem :)
