其他值得注意的症状:
我完全迷住了这一点,互联网上似乎没有任何东西可以帮助我。 我什至专注于首先尝试解决“ OpenGL version = null”问题,但是由于我要么错误地遵循了该网站上的建议(对OpenGL渲染上下文没有足够的了解),要么我空手而归。 0xC0000005错误的症状。
编辑:由于此问题似乎是由多个问题引起的,因此我决定放置代码的更新版本以及从中获取的相应错误。 到目前为止,感谢您对我的帮助,但是glGenBuffers似乎对我或其他事物怀恨在心。

错误:gl_crap3.obj:错误LNK2001:未解析的外部符号___glewGenBuffers
您的问题可能是未定义glGenBuffers。 我注意到您正在尝试使用GLEW解决此问题。 如您所料,您需要做更多的工作来设置GLEW。 您需要调用glewInit。 我的代码看起来像(为清楚起见简化):
GLenum err = glewInit();
if (err != GLEW_OK) {
string error = "GLEW extension loading failed: "+string((char*)glewGetErrorString(err));
printf("%s\n",error); getchar();
}
在设置上下文后(即在glutInit之后)添加该代码。 我不知道您的OpenGL版本是否为NULL(我上次遇到的是在相当旧的卡上),可能是集成芯片组。 如果是您的情况,则可能无需担心。
谢谢大家的帮助。 经过一周以上的研究,我相信问题可能出在Visual Studio 2010编译器本身09/08/2012上 。
我将尝试Linux以解决我的问题。
