How to use OpenGL3?

[con]

Hello, I am using SFML to do some OpenGL programming.

Currently I want to access OpenGL 3 API and I get this error.
error: 'glGenBuffers' was not declared in this scope

I have downloaded SFML from github and built it myself, GLEW should be included in SFML right?

GLEW is used internally, yes, but you still need to include it if you yourself want to use it too.

Don't forget to read the tutorials carefully!
