3年前写过一些关于如何使用Mesa的文章，如今再试。有些东西已经变了。

首先安装：

 

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

现在不用NetBeans了，用CMake创建工程。

 

根目录下的CMakeLists.txt内容：

 

cmake_minimum_required(VERSION 2.8)project (vender)add_subdirectory(src bin)

src目录下的CMakeLists.txt文件内容如下：

 

 

cmake_minimum_required(VERSION 2.8)set(CMAKE_BUILD_TYPE Debug)set(PROJECT_INCLUDE_DIR ../include)include_directories(${PROJECT_INCLUDE_DIR})AUX_SOURCE_DIRECTORY(${CMAKE_SOURCE_DIR}/src CPP_LIST1)add_executable(vender ${CPP_LIST1})target_link_libraries(vender GL GLU glut)add_definitions(-Wall)

 

 

然后看一下src/main.cc文件内容，和3年前代码一样。

 

#include 
    
     void init();void display();int main(int argc, char* argv[]) {  glutInit(&argc, argv);  glutInitDisplayMode(GLUT_RGB | GLUT_SINGLE);  glutInitWindowPosition(0, 0);  glutInitWindowSize(300, 300);  glutCreateWindow("OpenGL 3D View");  init();  glutDisplayFunc(display);  glutMainLoop();  return 0;}void init() {  glClearColor(0.0, 0.0, 0.0, 0.0);  glMatrixMode(GL_PROJECTION);  glOrtho(-5, 5, -5, 5, 5, 15);  glMatrixMode(GL_MODELVIEW);  gluLookAt(0, 0, 10, 0, 0, 0, 0, 1, 0);}void display() {  glClear(GL_COLOR_BUFFER_BIT);  glColor3f(1.0, 0, 0);  glutWireTeapot(3);  glFlush();}
    

运行结果：

 

我这次不想绘制什么图形，只是想知道我的显卡类型。因此代码删减如下：

 

#include 
    
     #include 
     
      using namespace std;int main(int argc, char* argv[]) {  glutInit(&argc, argv);  glutInitDisplayMode(GLUT_RGB | GLUT_SINGLE);  glutInitWindowPosition(0, 0);  glutInitWindowSize(300, 300);        glutCreateWindow("OpenGL 3D View");  GLubyte const* vender = glGetString(GL_VENDOR);  cout << "GL_VENDOR: " << vender << endl;  GLubyte const* renderer = glGetString(GL_RENDERER);  cout << "GL_RENDERER: " << renderer << endl;  GLubyte const* version = glGetString(GL_VERSION);  cout << "GL_VERSION: " << version << endl;  return 0;}
     
    

运行结果：
