[go-nuts] void type alias can not be understood in cgo

[hui zhang]

Check code below
go call c opengl/opengles code,   typedef void GLvoid

func GenVertexArrays(n int32, arrays *uint32) {
   //C.glGenVertexArrays((C.GLsizei)(n), (*C.GLuint)(unsafe.Pointer(arrays)))   
   --> ok on darwin amd64
   C.glGenVertexArraysOES((C.GLsizei)(n), (*C.GLuint)(unsafe.Pointer(arrays)))  
   --> fail on darwin arm
}

Error Message

cgo-gcc-prolog:36:10: error: field has incomplete type 'GLvoid' (aka 'void')
For the GLvoid(aka void)  can not be understood by cgo

function decalred
void *glGenVertexArrays*(GLsizei n, GLuint *arrays); -->on darwin amd64 
opengl

GLvoid glGenVertexArraysOES(GLsizei n, GLuint *arrays) -->on darwin arm opengles
