So the problem is: > /var/tmp/portage/x11-libs/gtk+-2.24.33-r2/work/gtk+-2.24.33/gtk/gtkscale.c:1474:50: error: incompatible function pointer types passing > 'GCompareFunc' (aka 'int (*)(const void *, const void *)') to parameter of type > 'GCompareDataFunc' (aka 'int (*)(const void *, const void *, void *)') > [-Werror,-Wincompatible-function-pointer-types] compare_marks is declared as > static gint > compare_marks (gconstpointer a, gconstpointer b, gpointer data) g_slist_insert_sorted_with_data takes a GCompareDataFunc: > GSList* g_slist_insert_sorted_with_data (GSList *list, > gpointer data, > GCompareDataFunc func, > gpointer user_data) G_GNUC_WARN_UNUSED_RESULT; The problem appears to be a stray (and unnecessary) cast to GCompareFunc: > priv->marks = g_slist_insert_sorted_with_data (priv->marks, mark, > (GCompareFunc) compare_marks, > GINT_TO_POINTER ( > gtk_range_get_inverted (GTK_RANGE (scale)) > )); We can fix that easily enough, but this is not really the only problem, is it?

I suspect we need to disable the compiler error for dead packages like gtk+:2.
