我有从opengl示例代码中获取的这段代码:
#include <GL/glut.h>
// Display callback ------------------------------------------------------------
void display()
{
// clear the draw buffer .
glClear(GL_COLOR_BUFFER_BIT); // Erase everything
// set the color to use in draw
glColor3f(0.5, 0.5, 0.0);
// create a polygon ( define the vertexs)
glBegin(GL_POLYGON); {
glVertex2f(-0.5, -0.5);
glVertex2f(-0.5, 0.5);
glVertex2f( 0.5, 0.5);
glVertex2f( 0.5, -0.5);
} glEnd();
// flush the drawing to screen .
glFlush();
}
// Keyboard callback function ( called on keyboard event handling )
void keyboard(unsigned char key, int x, int y)
{
if (key == 'q' || key == 'Q')
exit(EXIT_SUCCESS);
}
// Main execution function
int main(int argc, char *argv[])
{
glutInit(&argc, argv); // Initialize GLUT
glutCreateWindow("OpenGL example"); // Create a window
glutDisplayFunc(display); // Register display callback
glutKeyboardFunc(keyboard); // Register keyboard callback
glutMainLoop(); // Enter main event loop
return (EXIT_SUCCESS);
}
它应该工作正常吗?但是当我运行它时:

我正确安装了opengl,freeglut(我的意思是,它运行并且vc++发现没问题),但我无法运行我找到的任何源代码..(同样的错误)
