To compile the FM filemanager I need to have the missing symbol `gtk_object_check_cast'. The author of FM told my it should be in the gtk 1.2 development package. While I think I have installed any gtk 1.2 packages from potato I'm still missing this symbol. Could anybody tell me in exactly which package I need? Is there a possibility to "grep" through a list of debian packages to find any arbitrary string? O. Wyss
