Hi !
I wanted to run the graphical C source code without Desktop Environment !
For example, please look at this code :
#include <gtk/gtk.h>
int main(int argc, char *argv[]) {
GtkWidget *window;
gtk_init(&argc, &argv);
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_widget_show(window);
gtk_main();
return 0;
}
but it has Error !
it cant run in fedora without Desktop Environment !
Error is :
[MARSL@marsl ~]$ ./gtk_example_code
(gtk :6616): Gtk_WARNING **: 10:43:49.667: cannot open display:
but this code can run in Desktop Environment .
So how do desktops like GNOME that are made with GTK work?
