Fltk on BBB

[Destroy]

Hi all, I'm working on a porting from a custom linux distribution to a BBB environment.

If I use the BBB environment with debian user interface I have no problem, otherwise if I use the BBB environment without user interface I recieve the error "Can't open display".

What packages I need to install to use fltk without user interface?

Thank you in advance for all support.

According to Wikipedia, https://en.wikipedia.org/wiki/FLTK
"Fast Light Toolkit (FLTK, pronounced fulltick)[3] is a cross-platform
widget (graphical control element) library for graphical user interfaces
(GUIs)" -- it requires an underlying/compatible graphical system to be
available... So on Linux, that means some form of X-Window (Wikipedia says
Wayland is under development).

At a minimum, that likely means xlib and an environment definition to
an x-server (display).
