#
# This file demonstrates a parsing bug in make(1) from NetBSD-1.6.2 and
# the current pkgsrc bmake. The make from NetBSD-2.99.15 has been fixed.
#
# The bug is that one of the closing braces is parsed twice -- once as
# terminator for a variable and once as literal character, which is
# appended to PKG_OPTIONS.
OPTIONS= a b c d
MYOPTIONS= -b -c
OPTIONS_1:= ${OPTIONS}
.for _o_ in ${MYOPTIONS}
_opt_:= ${_o_}
. if !empty(_opt_:M-*)
OPTIONS_1:= ${OPTIONS_1:N${_opt_:C/-//}} # <-- the bug
. endif
.endfor
# This is a possible workaround for this bug. It defines an intermediate
# variable that reduces the complexity of the modifier expression.
OPTIONS_2:= ${OPTIONS}
.for _o_ in ${MYOPTIONS}
_opt_:= ${_o_}
_popt_:= ${_o_:C/-//} # <-- workaround, part 1
. if !empty(_opt_:M-*)
OPTIONS_2:= ${OPTIONS_2:N${_popt_}} # <-- workaround, part 2
