glGenVertexArrays 崩溃的处理方式

在运行红宝书8版的源码的时候，遇到glGenVertexArrays调用时崩溃的问题。解决方式是在glewInit()前加入glewExperimental = GL_TRUE;

要用这句代码来开启glew对扩展的支持

GLEW obtains information on the supported extensions from the graphics driver. Experimental or
pre-release drivers, however, might not report every available extension through the standard mechanism, in which case GLEW will report it unsupported. To circumvent this situation, the

glewExperimental

global
switch can be turned on by setting it to

GL_TRUE

before
calling

glewInit()

,
which ensures that all extensions with valid entry points will be exposed.
