Re: Defining new targets with eval during secondary expansion?

[Brian Vandenberg]

This is a bit nicer but there's still some duplication. What I'd like to do

is replace the argument on the right hand side with $(dir $@). With secondary

expansion enabled I could write something like this:

  mktargetdir = $(eval $(call mkdir_template,$(dir $@))) $(dir $@)

  .SECONDEXPANSION:

  build/foo/bar/baz/mytarget: | $$(mktargetdir)

Then I can just write the path for each target and all the duplication is gone.

But this doesn't work and I get the error above about prerequisites in recipes.

What if you changed the way you specify your targets, eg:

ASDF = $(foreach x, ${1}, $(eval $(call ${0}_, ${1}, $(dirname ${1})))) ${1}

define ASDF_ =

${1} :| ${2}

${2} : ; mkdir -p address@hidden

endef

$(call build/foo/bar/baz/mytarget) : other dependencies for mytarget

...
