I am sending the OpenGL programs as an attachment just change the signature of the main program from void to int and all of them should work fine

Then regarding the error message you mentioned i got the same error while working with Ubuntu (probably some display header file missing) I could not fix the error but however i tried the same program on Mandriva 2009  where i could compile and run the same program successfully this might not be the solution to your query but at least this can be of some help.
