Re: Segmentation Fault [Newbie]

[Larry Reaves <larry yrral net>]

Running through gdb, we can see it crashes on this line:

gtk_container_add(GTK_CONTAINER(window),menu_bar);

glancing through the code, this makes perfect sense because window is
never initialized.  The pointer window points to some random address.
Adding:

window = gtk_window_new(GTK_WINDOW_TOPLEVEL);

somewhere before gtk_container_add will fix your segfault.

Good luck,
Larry Reaves
