Compiling errors when compiling OpenGL with GLUT
 
Hello

I have just started to look at OpenGL, and I got the book "OpenGL Superbible 5th edition" by Richard. S. Wright, jr and others.

The code in the book makes use of various libs', for example GLUT, GLEW and a GLTools (Which is made by the books authors I think).

The problem is that when I compile the code from the first example application I get this error:

Also when running a pre-built example of the same source I am experiencing some problems:

I am running Crunchbang Linux Statler 64-bit, based on Debian. I have installed the correct nVidia Drivers for my GeForce 9600M GS card. I also have the following packages installed:
- libgl1-nvidia-legacy-96xx-glx(Also the -dev package)
- nvidia-legacy-96xx (Also -dev)
- nvidia-glx-dev
- libglew1.5 (Also -dev)
- libglut3 (Also -dev)
- freeglut3 (Also -dev)

As far as I understand, the freeglut3 packages should replace the libglut3, so I first tried without libglut3, but with the same result. I am also able to run other OpenGL applications like Tremulous and Minecraft.

Some other information:

I guess it's ok to post it here, it's freely available for download on the homepage for the book.

So, anyone having any ideas on what to do? :)

Why are you using the legacy drivers, why not the latest ones ?

I had same error on my fedora machine
Code:

undefined reference to `glViewport'
I installed glut dev environment:
Code:

yum install freeglut-devel
in your debian based machine it will be slightly different, but you get the idea.
I also added -lglut as an option to g++
Code:

g++ -lglut triangle.cpp -o triangle
Anyway, now the error is gone.

Mhm, I think I must have enabled it when I was searching around and trying different packages to solve this problem. Back on the newest drivers now.

Quakeboy02: I allerady have the freeglut-dev packages installed, so I don't think thats the problem.
