Question

我尝试将我的Angel的书的Windows代码移植到Mac并且得到GLSL版本150不支持错误，我确信我的计算机支持，我将glGenVertexArrays（）更改为glGenVertexArraysAPPLE（）

我不知道为什么会这样返回错误？

 void init(){
    glGenBuffers( 3, buffers );
    //Vertex buffer for the vertex coordinates
    glBindBuffer( GL_ARRAY_BUFFER, buffers[cube_vertices] );
    glBufferData( GL_ARRAY_BUFFER, sizeof(vertices), vertices, GL_STATIC_DRAW );

    //Elements buffer for the pointers
    glBindBuffer( GL_ELEMENT_ARRAY_BUFFER, buffers[cube_indeces] );
    glBufferData( GL_ELEMENT_ARRAY_BUFFER, sizeof(indices), indices, GL_STATIC_DRAW);

    glBindBuffer( GL_ELEMENT_ARRAY_BUFFER, buffers[wire_indeces] );
    glBufferData( GL_ELEMENT_ARRAY_BUFFER, sizeof(indices_wire), indices_wire, GL_STATIC_DRAW);


    glGenVertexArraysAPPLE(2, VAO);

对于非核心上下文，OSX在OpenGL 2.1（#version 120）上最高。

确保使用#version 150 core并从GLUT请求核心上下文。

从Windows到Mac的端口OpenGL代码返回版本'150'不受支持
