Thanks for all of your help. solved problem. the run-dialog is part of gnome-panel and the text input box in this dialog is of type GnomeEntry, which is defined by libgnomeui, and libgnomeui depend on libglade, when I was compiling, libglade was installed at another prefix because I want to share the same base library among multi gnome version, but then libgnomeui cannot install libgnome.so into the right place, thus libglade dont know how to deal with GnomeEntry. _______________________________________________ gnome-list mailing list gnome-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gnome-list
