When I use glGenVertexArrays() with sfml 1.6, I suffer from segmentation fault. But when I use glGenVertexArrays() with glfw, everything is ok. I don't know how to solve it.

Can you post a small, simple program that reproduces the problem?

This function is defined in GL3 or even 4, so you need:
- a 3.x or 4.x context (which SFML can't create -- but you can get one if you're lucky)
- GLEW or GLEE to handle extensions, as you probably don't have GL3/4 headers and therefore the function is not available directly

It's a pity that SFML can't create GL 3.x/4.x context.

SFML 1.6 can't.
SFML 2 can.

I failed to build SFML 2.0 in FreeBSD.

Yup, CMake files need to be patched.
