Trying to compile my first opengl/mesa app

Question

I'm trying to compile my first program openGL app.

This is my code:

#include <GL/gl.h>      
#include <GL/glu.h>     
#include <GL/glut.h>    

using namespace std;

int main(int argc, char** argv) {

    glutInit(&argc, argv);

    return 0;
}

I have then linked /usr/lib/libglut.a to the project.

When I try to compile I'm getting this error:

Any idea?

The clue is here: more undefined references to 'glVertex2i' follow

Basically you need to link against the OpenGL library as well (glVertex2i is an OpenGL function), glut doesn't provide OpenGL functions, only additional functions to make life easy.

Try adding -lGL to the command line (at the end).

EDIT: This is only true for the static version (/usr/lib/libglut.a). The shared object version knows how to find libGL, so you can simply use -lglut instead of /usr/lib/libglut.a.

Assuming you have all the shared libraries installed on your system, for a C source code:

gcc hello.c -o hello -lGL -lglut -lGLU

For a C++ code:

g++ hello.cpp -o hello -lGL -lglut -lGLU

Don't use the static libraries files.a if you really don't need to. Else you'll have to satisfy those dependencies on your own.
