I'm upgrading a very large flight simulation project to GTKMM 3 from 2.4. When running the Gtk::Application with a Gtk::ApplicationWindow on a separate thread from the main simulation thread, we receive multiple warnings:

GLib-GIO-CRITICAL **: g_application_run: assertion 'acquired_context' failed

But the GTK window does show and is functional. The code is compiled in debug mode. Thanks

  • There are a number of assertions in the gtkmm (& comp libraries) that warn about non-breaking runtime issues. You definitely need to gdb debug the app and backtrace until you find the error. The [following page](https://developer.gnome.org/glib/stable/glib-running.html) might help you with setting the appropriate flags. All in all, your question is too broad for any good answer. You might want to edit it with some code after some debugging (if you don't already fix it). – vanntile Jul 24 '20 at 16:53

solved for me:

sudo pacman --overwrite="*" -S flatpak
flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
flatpak update
