these foreach look like an overly complicated form of $(patsubst):
$(patsubst %,moo_%,$(DIRS))

It may look like it, but they aren't. What you've written is a simple
addprefix, while the foreach does some for of cartesian product
($(TARGETS)x$(DIRS)).

1. I checked in the fixes for the autotools targets after verifying
them (thank you btw!).
2. Inline mkdirs are bad, because mkdir's can fail or cause failures
over NFS due to excessive I/O, which is why I quickly removed the test
-d || mkdir -p logic in the 2nd major draft of the makefile
infrastructure.
3. Although your idea for fixing the lack of recursive make'ing is
good, what about this instead?
#
# A canned set of operations for leaf makes. This creates a series of
targets, like:
#
# $(subdir)-all $(subdir)-clean $(subdir)-install:
#
# 1 - Recursive targets to act upon.
# 2 - the subdirectory to do the leaf_make on.
#
define generate_dir_dep
ifndef __$(1)_dir_dep__
__$(1)_dir_dep__ = 1
$(1):
mkdir -p "$$@"
endif
endif
define leaf_make
$$(foreach recursive_target,$(1),$$(addprefix
$(2)-$$(recursive_target))): $(1)-%: $(2)
$(MAKE) -C $* -f ""$(abs_srcdir)/$$*/Makefile" $$(patsubst $(1)-%,%,$$@)
endef
$(foreach subdir $(SUBDIRS),$(eval $(call generate_dir_dep,$(subdir))))
$(foreach subdir,$(SUBDIRS),$(eval $(call leaf_make
$(RECURSIVE_TARGETS),$(subdir))
Ultimately I suppose, it's another means to a similar end. It's just a
bit more discrete as to what's going on in the operation... if this is
a good idea, I'll modify functions.mk to match this. $(abspath) //
$(realpath) junk is already a PITA, so it might be a good idea just to
remove it in favor of keeping things as-is.
Thanks,
-Garrett

Well, I can't say I got used to your generated rules and double dollars
(you've got $* instead of $$* in the above IMHO). But if you deem it
better, fine by me.

Yes, you're right on the s/\Q$*\E/\Q$$*\E/. The $$ is required, as
per http://www.gnu.org/software/make/manual/make.html#Eval-Function,
unless I use $(value) (I just tested out this function and it
functions as expected on 3.80).
My primary concern when we're doing these changes is that the
changes need to be as straightforward as possible. If you disagree,
please let me know. My offer was as much of a proposal as your's was.
I see a great deal of value in what you're proposing, so please feel
free to let me know what you feel :).
Thanks!

Hello,
I tried to make ltp with the -j switch and found the following problems:
- the autotools target fail because of missing dependency on aclocal.m4 (almost all autotools targets depend on it)
- the shell loop in generic_trunk_target makes the "all" rules of the subdirectories run strictly sequentially
This patch fixes these issues by adding dependencies to the autotools targets (it also deletes some of the duplicated targets from the realtime Makefile), and by making one target for each subdirectory in generic_trunk_target.
Note that I really don't know if this works on an arbitrary make version.
Regards
Jiri Palcek
