freeglut Error

Anonymous — Wed, 16 Apr 2008 14:46:09 -0000

when I try to open the program:

freeglut ERROR: Function <glutCreateWindow> called without first calling 'glutInit'.

I'm using a Gentoo Linux with all package at the last stable version on a 64bit system

My system is a Linux RedHat 9, with glut 3.7.12, make
3.79.1,
gcc 3.2.2 and XFree86 4.3.0.

I could not compile 3dfb 0.5.1 on my system, make gives
this output:

gcc -Wall -Wmissing-braces -x c++ -I/usr/include/
-L/usr/X11R6/lib -lX11 -lXi -lXmu -lglut -lGL -lGLU

and keep going too much more lines, and finally fails with:

3dfb-.5.1.o:109:890: warning: null character(s) ignored

I have build my own Makefile, that don't use the -x
option of the
gcc compiler; instead I move 3dfb-.5.1.c to
3dfb-.5.1.cpp, and
then the compiler detects automatically the language
from the file
name extension. After that it build and run correctly.
I have attach here my modified Makefile.
