Can't build red book source code ?!

Are red book source codes legit and checked ?

Becouse I get a lot of errors when I try to compile them and codes from other souces mostly work.

What errors?

The red book example code found here compiles fine (some of the GLU examples generate warnings due to incorrect types for callback pointer, but that’s all).

Maybe I didn’t install it correctly after all. When I download source code from link you gave me and type in terminal:

gcc aaindex.c -o test -lglut -lGLU -lGL

i get this

freeglut (./test): ERROR: Internal error in function fgOpenWindow

but this source code for example works well

#include "GL/freeglut.h"
#include "GL/gl.h"
#include <iostream>
/* display function - code from:
    
This is the actual usage of the OpenGL library. 
The following code is the same for any platform */
void renderFunction()
{
    glClearColor(0.0, 0.0, 0.0, 0.0);
    glClear(GL_COLOR_BUFFER_BIT);
    glColor3f(1.0, 1.0, 1.0);
    glOrtho(-1.0, 1.0, -1.0, 1.0, -1.0, 1.0);
    glBegin(GL_POLYGON);
        glVertex2f(-0.5, -0.5);
        glVertex2f(-0.5, 0.5);
        glVertex2f(0.5, 0.5);
        glVertex2f(0.5, -0.5);
    glEnd();
    glFlush();
}

/* Main method - main entry point of application
the freeglut library does the window creation work for us, 
regardless of the platform. */
int main(int argc, char** argv)
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_SINGLE);
    glutInitWindowSize(500,500);
    glutInitWindowPosition(100,100);
    glutCreateWindow("OpenGL - First window demo");
    glutDisplayFunc(renderFunction);
    glutMainLoop();    
    return 0;
}

btw not sure if it is important, my os is linux mint 17.2

I’d be very surprised if you can get that error just from compiling it.

But I wouldn’t be at all surprised if you got that from running that particular program on any system which was made within the last twenty years. The aaindex demo requires an indexed-colour mode (i.e. 256 colours, with a palette):


   glutInitDisplayMode (GLUT_SINGLE | GLUT_INDEX);

and those aren’t exactly common nowadays. Even if the hardware and X server supports such a mode, it won’t be the default, and I wouldn’t necessarily expect it to support OpenGL in that mode.

I’d expect the same issue for fogindex.c, which also uses indexed-colour. There may be a couple of other programs using features which aren’t likely to be supported by the default configuration of a modern system. But most of them should work fine. It’s perhaps a bit unfortunate that one of two programs with that issue happens to be the first one alphabetically.

First I would like to thank you for taking some of your time to reply to this.

I tried to compile second one and it works fine.

I still have one more question, which edition of red book is this ? The one I have has triangless.cpp for the first example, and I can’t find that source code in here. I am asking becouse I would like to learn from the same book these source codes came from so I can have better experience.

Once again thank you.

That version is from here, which says

Code Samples released by SGI with the OpenGL 1.1 distribution in 1997.

So I’d assume that corresponds to the first edition, which can be found online here.

This site has a link to “most of” the code for the 8th edition, which covers OpenGL 4.3.

So much changed between OpenGL 1.1 and 4.3 that they have almost nothing in common.
