I am receiving that error in all of my automake builds. The cause is the usual comparing a result to a non integer: if test "$kde_qtver" = "3"; then if test "$kde_qtsubver" -le 1; then trinity2ornewer= fi if test "$kde_qtsubver" -le 2; then trinity3ornewer= fi if test "$KDECONFIG" != "compiled"; then if test `$KDECONFIG --version | grep KDE | sed 's/KDE: \(...\).*/\1/'` = 3.2; then trinity3ornewer= fi fi fi Is this test looking to test against 3 or 2? I think 2 because 3 is already established in the first test of this snippet. Anyway, this needs a fixin'. Up to you Tim!
