Build on Windows #7

Open ysbaddaden opened 1 year ago

ysbaddaden commented 1 year ago

Gtk3 is available for Windows.

The problem is figuring out how to install Gtk3 dev and gintrospection, then get to a point where the gobject shard is running (you can compile and run samples).

Once Crystal and Gtk3 are setup, you should be able to build an executable for Windows?

I have zero knowledge of Windows. Help is welcomed!

Probably blocked by https://github.com/crystal-lang/crystal/pull/13419 since the app relies on MT, or we shall use another hack (call Fiber.yield in GLib.timeout_milliseconds callback) on Windows.

Alternatively we could try to integrate the Gtk event loop with Crystal event loop (see g_main_context_set_poll_func). The difficulty being that we can't block forever waiting for an event (the GPollFunc callback receives a timeout parameter), otherwise we'd block the UI.

Last alternative, start a thread to run Gtk and add a mechanism to exit the main thread when the Gtk thread has terminated (not before). I implemented that (to avoid some hacks) but we still need preview_mt to turn on thread safety guards.
