[apparmor] [PATCH] towards a common build infrastructure

[Seth Arnold]

Use $MAKE instead, that way the jobserver can keep informed about how many jobs sub-makes are using.

I do like that ./configure --prefix makes selecting between /usr and /usr/local easy but I have trouble seeing what else it gives us.

I'd guess even more people understand plain Makefiles ;-) and I can
guarantee you that nearly nobody understands the automake-generated
Makefiles (reading them might be needed to track down build issues)

Re-reading your patch a second time, I noticed that you are right.
I expected some + lines in the README patch, but you found a clever way 
to recycle the existing lines ;-)

Well, I remember (from another project) that plain Makefiles can work 
with subdirs without problems. Something like this will work as Makefile
in the top-level directory (untested braindump)


subdirs=changehat/mod_apparmor changehat/pam_apparmor libraries/libapparmor parser profiles utils

all:
	for dir in $(subdirs) ; do make -C $$dir || exit 1 ; done
clean:
	for dir in $(subdirs) ; do make -C $$dir clean || exit 1 ; done
install:
	for dir in $(subdirs) ; do make -C $$dir install || exit 1 ; done


And now tell me how automake can make things simpler than this ;-)

Hmm, I should have sent this as patch earlier - it would have been easier
than updating the spec with tons of "make -C" calls...

Christian Boltz
