How should I use shaders in GLFW? I used GLEW with GLUT but this is not working anymore.

GLEW should work just fine in combination with GLFW. I’ve done so for quite a while on three platforms, with no special cases needed. Just remember to include glew.h BEFORE glfw.h and you should be set.

Look at chapter 7 of the GLFW user’s guide. Everything you should need for extension suport is already there. You just need glext.h for the function prototypes.

Now i fixed, I found that GLEW has a small bug [https://sourceforge.net/mailarchive/forum.php?thread\_id=8076290&forum\_id=43720](https://sourceforge.net/mailarchive/forum.php?thread_id=8076290&forum_id=43720) i must initialize GLEW AFTER glcontext has been created, that means i can run glewInit after glfwOpenWindow has been called, not before, that was my mistake. Anyway, thanx for help.

That’s not a bug; it’s by by design. GLEW does not provide a facility for creating a context (that’s the job of GLFW), and the capabilities of a given context cannot be queried before its creation.

Great to hear it’s working!
