My OS is fedora 23. I have the mesa-libGL-devel and glfw-devel libs both installed.

I compile the program from the bottom of this page [http://www.glfw.org/docs/latest/quick.html](http://www.glfw.org/docs/latest/quick.html) with:  
gcc main.c -lglfw -lGL -o thing  
and it compiles no problem.

but when i ./thing i get:  
Segmentation fault (core dumped)

What gives, do I not have all the needed libs installed?  
!!!1111111!!!  
I SOLVED THE PROBLEM!  
I WAS ON GNOME WAYLAND AND I NEEDED ME TO BE ON GNOME X11!  
SORRY ALL

Excellent, glad you’ve solved it. GLFW now has experimental Wayland support but this needs to be selected via a compile option. See [http://www.glfw.org/docs/latest/news.html](http://www.glfw.org/docs/latest/news.html) for more.
