Does this library work for the Windows Linux Subsystem? #21

I successfully installed graphics and tried to run open_graph "" and obtained the following error: Graphic_failure "Cannot open display ".

I'm running OCaml and Opam in the windows Linux subsystem.

OCaml (and OPAM) installed in WSL works pretty much as on any other Unix distribution. In particular, you will probably need to install an X server in order to work with GUI programs.

Yep, that did the trick. My default window is now just appearing and instantly disappearing. Any insights on that? Sorry, if this no longer pertains to the issue I initially raised.

Are you doing anything after creating the Graphics window? If not, the program will terminate right away and take down the window with it.

For example, you can call Graphics.read_key to block until a key is pressed.
