I've been searching for a Linux distribution (on a live cd) with support for OpenGL development in C/C++ (other languages would be nice as well). Any distros come to mind?

I've been using this simple program and make file to test if the gl, glu, and glut libraries are present (by just trying to make).

main.cpp

#ifndef MAIN_CPP
#define MAIN_CPP

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

using std::cout;



void init()
{
	glClearColor(0.0f, 0.0f, 0.0f, 0.0f);
	glEnable(GL_DEPTH_TEST);
}

void renderScene()
{
	glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);


	glBegin(GL_LINES);
		glVertex3f(0.0, 0.0, 0.0);
		glVertex3f(0.0, 1.0, 0.0);

	glEnd();




	glutSwapBuffers();

}

void keyboardfunc(unsigned char c, int x, int y)
{
	switch (c)
	{
		case 't':
			glRotatef(4.0, 0.0, 0.0, 1.0);
			break;
		case 'y':
			glRotatef(-4.0, 0.0, 0.0, 1.0);
			break;



		case 'u':
			glRotatef(4.0, 0.0, 1.0, 0.0);
			break;
		case 'i':
			glRotatef(-4.0, 0.0, 1.0, 0.0);
			break;



		case 'o':
			glRotatef(4.0, 1.0, 0.0, 0.0);
			break;
		case 'p':
			glRotatef(-4.0, 1.0, 0.0, 0.0);
			break;



		case 'w':
			glTranslatef(0.0, 1.0, 0.0);
			break;
		case 'a':
			glTranslatef(-1.0, 0.0, 0.0);
			break;
		case 's':
			glTranslatef(0.0, -1.0, 0.0);
		case 'd':
			glTranslatef(1.0, 0.0, 0.0);
			break;


	}
	renderScene();
}



void changeSize(int w, int h)
{
	//currentWindowWidth = w;
	//currentWindowHeight = h;

	float angle=0.0;
	float x=0.0f,y=1.75f,z=5.0f;
	float lx=0.0f,ly=0.0f,lz=-1.0f;
	float ratio=1.0;

	// Prevent a divide by zero, when window is too short
	// (you cant make a window of zero width).
	if(h == 0)
		h = 1;

	ratio = 1.0f * w / h;
	// Reset the coordinate system before modifying
	glMatrixMode(GL_PROJECTION);
	glLoadIdentity();

	// Set the viewport to be the entire window
	glViewport(0, 0, w, h);

	// Set the clipping volume
	gluPerspective(45,ratio,1,1000);
	glMatrixMode(GL_MODELVIEW);
	glLoadIdentity();
	gluLookAt(x, y, z,
			  x + lx,y + ly,z + lz,
			  0.0f,1.0f,0.0f);
}


int main(int argc, char **argv)
{
	cout << "In main()\n";
	glutInit(&argc, argv);
	glutInitDisplayMode(GLUT_DEPTH | GLUT_DOUBLE | GLUT_RGBA);
	glutInitWindowPosition(100,100);
	glutInitWindowSize(300,300);
	glutCreateWindow("simple beginning");

	init();

	glutKeyboardFunc(keyboardfunc);
	//glutMouseFunc(mousefunc);

	glutDisplayFunc(renderScene);
	//glutIdleFunc(renderScene);
	glutReshapeFunc(changeSize);


	glutMainLoop();

	return(0);

You could just try locate gl.h Although I don't know if most live linux distros ship with many developer libraries. Usually you install linux and can then download anything you need.

Ubuntu LiveCD might work. $ sudo apt-get install build-essential to install things like GCC, make, autoconf, etc.

I'm trying to find something that would work without needing to download the libraries. I might try making my own live CD (just by including these libraries in an existing one...not sure on how to do that yet though) if I can't find one that works.

Most livecd's don't ship with an updated slocate database, so that probably wouldn't work without running "sudo updatedb" first.

I think Slax lets you add packages (from their site) like GCC to the iso pretty easily. Might be worth a look.

Wow! I'm really impressed with Slax just from reading some about it. I'm downloading it right now and I'll play around with updating the iso before burning it. Thanks for the tip.
