我尝试设置一个简单的VisualStudio2010 OpenGL项目

我从一个新的Win32项目开始,用以下代码替换_tWinMain:

int APIENTRY _tWinMain(HINSTANCE hInstance,
                     HINSTANCE hPrevInstance,
                     LPTSTR    lpCmdLine,
                     int       nCmdShow)
{
    UNREFERENCED_PARAMETER(hPrevInstance);
    UNREFERENCED_PARAMETER(lpCmdLine);

    // TODO: Place code here.
    //MSG msg;
    HACCEL hAccelTable;

    // Initialize global strings
    LoadString(hInstance, IDS_APP_TITLE, szTitle, MAX_LOADSTRING);
    LoadString(hInstance, IDC_GLPREDICTOR, szWindowClass, MAX_LOADSTRING);
    MyRegisterClass(hInstance);

    // Perform application initialization:
    if (!InitInstance (hInstance, nCmdShow))
    {
        return FALSE;
    }

    HDC hdc = GetDC(hWnd);
    if (hdc == NULL)
        return FALSE;
    if(!SetPF(hdc))
        return FALSE;

    mainApp = new GLPredictor(hdc);

    HGLRC tmpContext = wglCreateContext (hdc);
    wglMakeCurrent(hdc, tmpContext);

    //create opengl 4.2 context
    /*GLenum error = glewInit();
    if(error != GLEW_OK)
        return false;
    int attributes[] = {WGL_CONTEXT_MAJOR_VERSION_ARB, 4,
                        WGL_CONTEXT_MINOR_VERSION_ARB, 2,
                        WGL_CONTEXT_FLAGS_ARB, WGL_CONTEXT_FORWARD_COMPATIBLE_BIT_ARB,
                        0
                        };

    if(wglewIsSupported("WGL_ARB_create_context")==1){
        HGLRC context = wglCreateContextAttribsARB(hdc, NULL,attributes);
        wglMakeCurrent(NULL, NULL);
        wglDeleteContext(tmpContext);
        wglMakeCurrent(hdc,context);
    }
    else{
        return FALSE;
    }

    int glVersion[2] = {-1,-1};
    glGetIntegerv(GL_MAJOR_VERSION, &glVersion[0]);
    glGetIntegerv(GL_MINOR_VERSION, &glVersion[1]);
    std::cout<<"Using OpenGL: "<<glVersion[0]<<"."<<glVersion[1]<<std::endl;
    */

    hAccelTable = LoadAccelerators(hInstance, MAKEINTRESOURCE(IDC_GLPREDICTOR));

    MSG msg = {0};
    while(TRUE)
    {
        // Check to see if any messages are waiting in the queue
        if(PeekMessage(&msg, NULL, 0, 0, PM_REMOVE))
        {
            TranslateMessage(&msg);
            DispatchMessage(&msg);
            if(msg.message == WM_QUIT)
                break;
        }
        else
        {
            mainApp->render();
        }
    }

    return (int) msg.wParam;
}

此操作。

但是只要我取消注释注释区域(//创建opengl 4.2上下文)并尝试运行应用程序,我就会立即收到一条错误消息:

The application was unable to start correctly (0x000007b). Click OK to close the application.

但是甚至没有达到未注释的代码。我甚至可以在_tWinMain的第一行设置一个断点,它不会被触发。

我已经尝试创建一个新项目并将代码复制过来,结果相同。

任何人都知道为什么这个区域导致项目崩溃,即使它包含的代码已经执行了?

//编辑:违规行似乎是

 GLenum error = glewInit();

一旦它出现在代码中,就会使应用程序崩溃(尽管代码执行永远不会到达它)。这行是否会导致编译器添加一些可能导致问题的内容?

答案 0 :(得分:-1)

好的 - 我明白了。我不得不将“glew32.dll”复制到我的SysWOW64目录
