Re: how to exit the parent_make immediately when get an error in submake

[Tao T]

unfortunately it dose not work. I change the code as you suggest:BUILDUNITS
:= $(shell $(foreach unit,$(ALL_UNITS),cd
$(REPOSITORY_ROOT)/units/$(unit)/source/sc/beh && $(MAKE) $(MAKECMDGOALS)
BUILD_TYPE=$(BUILD_TYPE) 1>&2 && true)) or BUILDUNITS := $(shell $(foreach
unit,$(ALL_UNITS),cd $(REPOSITORY_ROOT)/units/$(unit)/source/sc/beh &&
$(MAKE) $(MAKECMDGOALS) BUILD_TYPE=$(BUILD_TYPE) 1>&2;) && true)
both doesn't work.
maybe I write in a wrong way. do you have any other suggestion?
Thank in advanced,

 Tao
