X11/Xlib.h not found in Ubuntu

Question

I\'m trying to write a rather trivial program using open gl on linux, but at a compile time it says:

Compile thumb : egl <= cuberenderer.c In file i

Answer 1

A quick search using...

apt search Xlib.h

Turns up the package libx11-dev but you shouldn't need this for pure OpenGL programming. What tutorial are you using?

You can add Xlib.h to your system by running the following...

sudo apt install libx11-dev
