OpenGL創建渲染上下文失敗

我正在C++上編寫一些OpenGL 3程序，現在我的筆記本電腦Lenovo Thinkpad e320（Intel HD Graphics 3000）出現問題。它可以在我的電腦上正常工作（ATI Radeon HD 5870）。錯誤附近OpenGL創建渲染上下文失敗

守則如下：

bool GLWindowCreate(const char *title, int width, int height, bool fullScreen){ 
... 
    g_hRC = wglCreateContextAttribsARB(g_hDC, 0, attribs); 
    if (!g_hRC || !wglMakeCurrent(g_hDC, g_hRC)) 
    { 
     LOG_ERROR("Creating render context fail (%d)\n", GetLastError()); 
     return false; 
    } 
... 
}

所有編譯罰款，我看到在日誌文件中此錯誤。

我使用Windows 8（PC和筆記本電腦）。對筆記本電腦的顯卡支持OpenGL 3.我發現有關我需要關閉硬件加速同樣的問題，一些答案，但似乎沒有辦法在Win做到這一點8.

補充：

整個窗口創建功能：

我們需要查看更多的上下文創建代碼，以瞭解發生了什麼。 –

「聯想** Thikpad **」？ – genpfault

更正了:) – Anatoly

我意外地發現了一個決定。問題是有：

int attribs[] = 
    { 
     WGL_CONTEXT_MAJOR_VERSION_ARB, 3, 
     WGL_CONTEXT_MINOR_VERSION_ARB, 3, 
     WGL_CONTEXT_FLAGS_ARB,   WGL_CONTEXT_FORWARD_COMPATIBLE_BIT_ARB, 
     WGL_CONTEXT_PROFILE_MASK_ARB, WGL_CONTEXT_CORE_PROFILE_BIT_ARB, 
     0 
    };

英特爾高清顯卡3000僅支持的OpenGL 3.1，而不是3.3的，所以我不得不改變

WGL_CONTEXT_MINOR_VERSION_ARB, 3,

到

WGL_CONTEXT_MINOR_VERSION_ARB, 1,

謝謝大家和擔心難過，希望我的問題解決方案能夠幫助別人
