所以我一直在关注一个教程,当我尝试编译以下代码时:
#include <glut.h>
#include <iostream>
void render(void);
void keyboard(unsigned char c, int x, int y);
void mouse(int button, int state, int x, int y);
int main(int argc, char** argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DEPTH | GLUT_DOUBLE | GLUT_RGBA);
glutInitWindowPosition(100, 100);
glutInitWindowSize(640, 480);
glutCreateWindow("Test GLUT App");
glutDisplayFunc(render); // render
glutKeyboardFunc(keyboard);
glutMouseFunc(mouse);
glutMainLoop(); // initialization finished. start rendering
}
void render(void)
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glBegin(GL_TRIANGLES);
glColor3f(0.5, 0.2, 0.9);
glVertex2f(-0.5, -0.5);
glColor3f(0.1, 0.2, 0.5);
glVertex2f(0.0, -0.5);
glColor3f(0.3, 0.9, 0.7);
glVertex2f(0.0, 0.5);
glEnd();
glutSwapBuffers();
}
void keyboard(unsigned char c, int x, int y)
{
if(c == 27)
{
exit(0);
}
}
void mouse(int button, int state, int x, int y)
{
if(button == GLUT_RIGHT_BUTTON)
{
exit(0);
}
}
我突然收到3 个错误:
错误 1 错误 C2381: 'exit' : 重新定义;__declspec(noreturn) 不同 c:\program files (x86)\microsoft visual studio 10.0\vc\include\stdlib.h 353
错误 2 错误 C3861: 'exit': identifier not found ....main.cpp 45
错误 3 error C3861: 'exit': identifier not found ....main.cpp 53
有谁知道为什么会出现这个错误?我正在使用 VS2010。
