Olá,

Posta o código, mas acredito que ele não esteja encontrando, ou você digitou algo errado.

amigo tem uns exemplos no gtk-demo eu tirei dali o codigo fonte, o codigo é assim.

#include <gtk/gtk.h>

static GtkWidget *
create_bbox (gint horizontal,
char *title,
gint spacing,
gint layout)

if (horizontal)
bbox = gtk_hbutton_box_new ();
else

gtk_container_set_border_width (GTK_CONTAINER (bbox), 5);
gtk_container_add (GTK_CONTAINER (frame), bbox);

Olá,

Onde está a função main()?
Todo programa em C e em C++ precisa iniciar por ela, não?
Grato,
