The code compiles fine but gives this error on run: freeglut (filename): failed to open display ''

How do I set the display and get it to run? Also trying to open xterm gives the same error (tried this as advice found said to run in an xterm).

Answer 1

You need a running X server, so that X11 based programs can display output. However if your goal is OpenGL development on Windows then you should not use a X server, because, unfortunately, none of the existing X servers for Windows does support modern OpenGL features in their implementation of GLX client and server components.

I strongly suggest you target native Windows GDI when compiling for windows.
