先装个freeglut或者mesa。
以freeglut举例,装好后会在/usr/include/GL中出现glut.h,在/usr/lib下出现libglut.so,如果没有就自己拷一下。
然后写个测试程序,如test.c,用以下命令编译:
gcc -lglut test.c -o test
生成可执行文件test,然后:
./test
看到方框说明安装成功:)
如手上没有现成的测试例子,附件是openGL红宝书的第一个例子hello.c
- #include <GL/glut.h>
- void display(void)
- {
- /* clear all pixels */
- glClear (GL_COLOR_BUFFER_BIT);
- /* draw white polygon (rectangle) with corners at
- * (0.25, 0.25, 0.0) and (0.75, 0.75, 0.0)
- */
- glColor3f (1.0, 1.0, 1.0);
- glBegin(GL_POLYGON);
- glVertex3f (0.25, 0.25, 0.0);
- glVertex3f (0.75, 0.25, 0.0);
- glVertex3f (0.75, 0.75, 0.0);
- glVertex3f (0.25, 0.75, 0.0);
- glEnd();
- /* don't wait!
- * start processing buffered OpenGL routines
- */
- glFlush ();
- }
- void init (void)
- {
- /* select clearing color */
- glClearColor (0.0, 0.0, 0.0, 0.0);
- /* initialize viewing values */
- glMatrixMode(GL_PROJECTION);
- glLoadIdentity();
- glOrtho(0.0, 1.0, 0.0, 1.0, -1.0, 1.0);
- }
- /*
- * Declare initial window size, position, and display mode
- * (single buffer and RGBA). Open window with "hello"
- * in its title bar. Call initialization routines.
- * Register callback function to display graphics.
- * Enter main loop and process events.
- */
- int main(int argc, char** argv)
- {
- glutInit(&argc, argv);
- glutInitDisplayMode (GLUT_SINGLE | GLUT_RGB);
- glutInitWindowSize (250, 250);
- glutInitWindowPosition (100, 100);
- glutCreateWindow ("hello");
- init ();
- glutDisplayFunc(display);
- glutMainLoop();
