layout (location) requires " #extension GL_ ARB_ separate_ shader_ objects : enable before use or

初学Opengl的过程中，第一次编写着色器显示layout (location) requires ” #extension GL_ ARB_ separate_ shader_ objects : enable before use or or #version410
和gl_Position is not accessible in this profile

最后发现是
GLuint programID = LoadShaders( “SimpleVertexShader.vertexshader”, “SimpleFragmentShader.fragmentshader” );
里面的两个参数写反了

望大家引以为戒
