linux下基于eclipse的opengl开发环境搭建
转自：http://www.cnblogs.com/lycheng/archive/2011/09/13/2174831.html

1. 安装OpenGL相关工具

　　sudo apt-get install mesa-common-dev libgl1-mesa-dev libglu1-mesa-dev freeglut3-dev

       其中，
       libgl1-mesa-de 对应 GL库;
       libglu1-mesa-dev对应GLU库 TJe opengl utility library；
      freeglut3-dev 对应glut库
      mesa-common-de ：This package includes the specifications for the Mesa-specific OpenGL extensions, the complete set of release release notes and the development header files common to all Mesa packages.

2. 设置Eclipse
        安装eclipse   cdt插件
        8.0.0 下载地址： http://www.eclipse.org/cdt/downloads.php

　　Project -> properties -> C / C++ Build / Settings -> Tool Setting

　　然后选择Cross G++ Linker 选择 Libraries，在Libraries 中插入： glut GL GLU

　　　　　　　　　　　　　　　　　　　　　在Libraries Search Paths 中插入： /usr/include/GL

3. 测试代码 example.cpp

#include <GL/glut.h>
#define window_width 640
#define window_height 480
// Main loop

void main_loop_function()
{
// Z angle

    static float angle;
// Clear color (screen)

// And depth (used internally to block obstructed objects)

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
// Load identity matrix

    glLoadIdentity();
// Multiply in translation matrix

    glTranslatef(0, 0, -10);
// Multiply in rotation matrix

    glRotatef(angle, 0, 0, 1);
// Render colored quad

    glBegin(GL_QUADS);
    glColor3ub(255, 000, 000);
    glVertex2f(-1, 1);
    glColor3ub(000, 255, 000);
    glVertex2f(1, 1);
    glColor3ub(000, 000, 255);
    glVertex2f(1, -1);
    glColor3ub(255, 255, 000);
    glVertex2f(-1, -1);
    glEnd();
// Swap buffers (color buffers, makes previous render visible)

    glutSwapBuffers();
// Increase angle to rotate

    angle += 0.25;
}
// Initialze OpenGL perspective matrix

void GL_Setup(int width, int height)
{
    glViewport(0, 0, width, height);
    glMatrixMode(GL_PROJECTION);
    glEnable(GL_DEPTH_TEST);
    gluPerspective(45, (float) width / height, .1, 100);
    glMatrixMode(GL_MODELVIEW);
}
// Initialize GLUT and start main loop

int main(int argc, char** argv)
{
    glutInit(&argc, argv);
    glutInitWindowSize(window_width, window_height);
    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE);
    glutCreateWindow("GLUT Example!!!");
    glutIdleFunc(main_loop_function);
    GL_Setup(window_width, window_height);
    glutMainLoop();
    return 0;
}

　　Run All 之后，会显示旋转的方型，如果不需要IDE，则可用命令行编译。

4. 命令行编译

　　gcc example.cpp -o example -lglut -lGL -lGLU

　　-o 表示输出的文件名

　　-l 表示链接的库
