7 years ago So, for anyone running into this issue by googling it, the easy solution is to use xvfb, if you run the command as:
xvfb-run raco video <blah>Then you can run video in headless mode. This is indicative of a much larger problem, namely, that video should only try to spin up a GUI when you are trying to preview a video, as it doesn't need one for just rendering.
When connecting via SSH to a computer with no attached monitor (running Debian Stretch), the following error occurred when trying
raco video:Unable to init server: Could not connect: Connection refused Gtk initialization failed for display ":0" context...: /usr/racket/share/pkgs/gui-lib/mred/private/wx/gtk/queue.rkt: [running body] /usr/racket/share/pkgs/gui-lib/mred/private/wx/gtk/init.rkt: [traversing imports] /usr/racket/share/pkgs/gui-lib/mred/private/wx/gtk/platform.rkt: [traversing imports] /usr/racket/share/pkgs/gui-lib/mred/private/wx/platform.rkt: [running body] /usr/racket/share/pkgs/gui-lib/mred/private/kernel.rkt: [traversing imports] /usr/racket/share/pkgs/gui-lib/mred/private/mred.rkt: [traversing imports] /usr/racket/share/pkgs/gui-lib/mred/mred.rkt: [traversing imports] /usr/racket/share/pkgs/gui-lib/mred/main.rkt: [traversing imports] /usr/racket/share/pkgs/gui-lib/racket/gui/base.rkt: [traversing imports] /home/benchung/.racket/6.9/pkgs/video/video/player.rkt: [traversing imports] /home/benchung/.racket/6.9/pkgs/video/video/raco.rkt: [traversing imports] (submod /home/benchung/.racket/6.9/pkgs/video/video/raco.rkt main): [traversing imports] /usr/racket/collects/raco/raco.rkt: [running body] /usr/racket/collects/raco/main.rkt: [running body]
