Hello readers,

We are going to learn how to compile gtk3 for XQuartz on big sur.

To compile use this:

gcc `pkg-config –cflags gtk+-3.0` -o example-0 mainwindow.cc `pkg-config –libs gtk+-3.0`

But first, open my gtk gist:

https://gist.github.com/vic3t3chn0/2e082126a7f89330f04cf2b10ba6e8c2

But you can test it like this:

#include <gtk/gtk.h>

static void
activate (GtkApplication* app,
          gpointer        user_data)
{
  GtkWidget *window;

  window = gtk_application_window_new (app);
  gtk_window_set_title (GTK_WINDOW (window), "Window");
  gtk_window_set_default_size (GTK_WINDOW (window), 200, 200);
  gtk_widget_show_all (window);
}

int
main (int    argc,
      char **argv)
{
  GtkApplication *app;
  int status;

  app = gtk_application_new ("org.gtk.example", G_APPLICATION_FLAGS_NONE);
  g_signal_connect (app, "activate", G_CALLBACK (activate), NULL);
  status = g_application_run (G_APPLICATION (app), argc, argv);
  g_object_unref (app);

  return status;
}

in the end:

 gcc `pkg-config --cflags gtk+-3.0` -o example-0 mainwindow.cc `pkg-config --libs gtk+-3.0`
