我只是想使用 SDL 2.0 和 glew 1.9 制作一个 openGL 上下文
构建项目时没有问题,但在调试时,GLEW 初始化失败,我该怎么做才能解决这个问题?
我正在使用视觉工作室 2012
这是输出:
The program '[936] gravitation.exe' has exited with code -1 (0xffffffff).
这是代码:
#include <GL/glew.h>
#include <SDL.h>
#include <iostream>
int main(int argc, char **argv)
{
SDL_Window* window = 0;
SDL_GLContext contextOpenGL = 0;
SDL_Event event;
bool terminate = false;
GLenum initGLEW = glewInit();
if( GLEW_OK != initGLEW )
{
std::cout << "initialisation error of GLEW : " << glewGetErrorString(initialisationGLEW) << std::endl;
SDL_GL_DeleteContext(contextOpenGL);
SDL_DestroyWindow(window);
SDL_Quit();
return -1;
}
while(!terminate)
{
SDL_WaitEvent(&event);
if(event.window.event == SDL_WINDOWEVENT_CLOSE)
terminer = true;
glClear(GL_COLOR_BUFFER_BIT);
SDL_GL_SwapWindow(window);
}
SDL_GL_DeleteContext(contextOpenGL);
SDL_DestroyWindow(window);
SDL_Quit();
return 0;
}
