Unquoting OVERLAY will make it work: $(Q)$(checkconfig) check -r "$(RULES)" -c "$(KCONFIG_CONFIG)" $(addprefix -o , $(OVERLAY)) But it breaks the consistent pattern of quoting all passed variables. So, can we keep it as it was originally done? Namely: checkconfig_overlay = $(if $(OVERLAY),-o "$(OVERLAY)") ... checkconfig: ... $(Q)$(checkconfig) check -r "$(RULES)" -c "$(KCONFIG_CONFIG)" $(checkconfig_overlay) Thanks! -- Ahmed S.
