Hi.

I'm working on the astlinux project (www.astlinux.org) and had a question about doing a build for only a subset of the $SUBDIRS targets.

I tried doing something like:

make -C $(ALSA-LIB_DIR) \ SUBDIRS='src include modules aserver'

but this fails. The problem is that if we look into the environment in the top-level $(RECURSIVE_TARGETS): we get:

SUBDIRS=include src modules aserver ... MAKEFLAGS=w --jobserver-fds=3,4 -j -- SUBDIRS=include\ src\ modules\ aserver CC=/home/philipp/asterisk/build_i586/staging_dir/bin/i586-linux-uclibc-gcc

so those targets eventually get picked up by the make running in include/, which then overrides his own Makefile value:

SUBDIRS = sound

and tries to build the same top-level targets now in include/. Clearly this is wrong.

Anyone have a work-around to this? We're on an embedded system, and don't want to build (nor install, obviously) "doc", "test", "alsalisp", "utils", etc.

Having something like:

SUBDIRS=$(filter-out $(SUBDIRS_EXCLUDE),$(SUBDIRS))

would be really sweet. Then I could just build as:

make -C $(ALSA-LIB_DIR) \ all SUBDIRS_EXCLUDE='doc test utils'

and only get the targets I want...

Thanks,
