未findglXCreateContextAttribsARB在OpenGL 4.2驱动程序，GLX 1.4上

奇怪的是，尽pipe我有GLX 1.4，但是在我的回购中没有glXCreateContextAttribsARB 。

我想知道这是否有合理的解释？ 这不是一个普遍的问题。

显然缓冲绑定， ARB和所有其他好的东西都支持，但为什么不是glXCreateContextAttribsARB ？

当你说“没有”时，我假设你的意思是“如果我试图直接调用这个名字的函数，我的应用程序将不会链接”。

这是有点设计。 直接从libGL导出的函数列表没有增长。 如果是这样的话，一个与新libGL链接的应用程序将无法启动， 那很糟。

glXCreateContextAttribsARB和所有其他扩展函数一样，应该使用glXGetProcAddressARB 。 更好的是，使用GLEW，所以你不必再担心这个级别的细节。
