When I make the code on the terminal, it gives me this error:
fatal error: GL3/gl3.h: No such file or directory
So I changed on the cube2equirect.h the #include <GL3/gl3.h> to #include <GL/gl.h>
It solved the error but when I make it again this appened

I don't know how to solve this, I am using Ubuntu and I need much a code like this for my projects.
