In order to show if gtk is correctly installed show pkg-config list result :

$ pkg-config --list-all | grep gtk

You must obtain a result like this :

gtk+-3.0                       GTK+ - GTK+ Graphical UI Library

gtk+-broadway-3.0              GTK+ - GTK+ Graphical UI Library

gtk+-unix-print-3.0            GTK+ - GTK+ Unix print support

gtk+-wayland-3.0               GTK+ - GTK+ Graphical UI Library

gtk+-x11-3.0                   GTK+ - GTK+ Graphical UI Library

Testing

Create a main.c file with the code below :

#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;
}

Compilation

Compile the code with gcc

$ gcc main.c -o main -Wall `pkg-config --cflags gtk+-3.0` `pkg-config --libs gtk+-3.0`
