When using instancing in OpenGL under OS X Mavericks and Qt5 see this post for my code I cannot compile when using the function glVertexAttribDivisor the error being
erreur : use of undeclared identifier 'glVertexAttribDivisor'; did you mean 'glVertexAttribDivisorARB'?
I went and used the ARB function but don't know what's the difference between the function with the suffix and the one without it. Can anyone explain me?
Also, is there a way or something I am missing in order to be able to use the correct function (meaning the one without the ARB suffix)?
