Try cabal install gtk -fhave-quartz-gtk. I think this is a duplicate of #112 (where we cannot easily tell if the gtk we are building against is quartz or x11).

Thanks. I've had this problem when installing threadscope and turning have-quartz-gtk on fixed it.

[bsdshell]

can we just add "gtk -fhave-quartz-gtk" as dependency to .yaml or .cabal in Stack instead of
"cabal install gtk -fhave-quartz-gtk" globally?

Yes, you can set cabal flags a number of different ways. If the project uses cabal new-build and a cabal.project file add (you can add it to cabal.project or cabal.project.local):

package gtk
  flags: +have-quartz-gtk

If it uses stack and a stack.yaml file add:

flags:
  gtk:
    have-quartz-gtk: true

Keep in mind though that people with the X11 version of Gtk+ 2 on macOS will not be able to build if this flag is set.
