Hello, help-make
I'd like to tell a strange behavior of make.
For GNU make 3.81 & 3.80. Can someone tell me why the running output from 'all'
and 'all2' are different?
ifeq ($(SHOW_CMD),1) Q =else Q = @endif
define _DO_LINK echo "smash it." echo "smash done."endef
all: $(if $(SHOW_CMD),,@)$(_DO_LINK)
all2: @$(_DO_LINK){code}
Output:
$ make -f sn.mksmash it.echo "smash done."smash done.
$ make all2 -f sn.mksmash it.smash done.
For target 'all', the @ suppress only the first command in $(_DO_LINK). Can
this be make's bug?
Best Regards
Chen Jun (陈军)
