I am not sure this is the right forum for this question, but if not free free to bump me to the right one.

I am running Ubuntu 12.04. I have been trying to learn how to use graphics in C. I have the Gnome 3 development files installed on my machine, which include all the GKT3 files. However, when I try to complile the following code I get a 'no such file or directory' error message referring to the gtk header files. I am sure I am missing some simple thing but I am not experienced enough to know what it is. Can someone point me in the right direction?


#include <gtk/gtk.h>
int main (int argc, char *argv[])
    GtkWidget *window;
    GtkWidget *label;
    gtk_init(&argc, &argv);
    /* Create the main, top level window */
    window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    /* Give it the title */
    gtk_window_set_title(GTK_WINDOW(window), "Hello, world!");
    ** Map the destroy signal of the window to gtk_main_quit;
    ** When the window is about to be destroyed, we get a notification and
    ** stop the main GTK+ loop by returning 0
    g_signal_connect(window, "destroy", G_CALLBACK(gtk_main_quit), NULL);
    ** Assign the variable "label" to a new GTK label,
    ** with the text "Hello, world!"
    label = gtk_label_new("Hello, world!");
    /* Plot the label onto the main window */
    gtk_container_add(GTK_CONTAINER(window), label);
    /* Make sure that everything, window and label, are visible */
    ** Start the main loop, and do nothing (block) until
    ** the application is closed
    return 0;
