ALT_OUTPUTDIR=$(OUTPUTDIR)
doesn't make sense to me.
The makefiles will define OUTPUTDIR to be equal to $(ALT_OUTPUTDIR) if
ALT_OUTPUTDIR is set.
The _OUTPUTDIR is the default build location, when ALT_OUTPUTDIR is not set.
The original idea here in setting ALT_OUTPUTDIR=$(_OUTPUTDIR)-$(DEBUG_NAME)
was to put all the results of a debug build in a completely different
directory, which I still think is right.
I suspect this needs to be:
ALT_OUTPUTDIR=$(OUTPUTDIR)-$(DEBUG_NAME)
A long time ago, the debug files were built along side the normal files, and
all debug files had that "_g" suffix (e.g. jvm_g.dll, etc.) but we completely
got rid of that because it was a nightmare.
The debug builds then just became a second pass over the source with the same
makefiles but just a different output directory so they didn't mix.
I'm afraid using ALT_OUTPUTDIR=$(OUTPUTDIR) will mix up the optimized files
with the debug files, which won't be good.

I would suggest to fix the top-level Makefile such that
COMMON_DEBUG_FLAGS uses $(OUTPUTDIR) instead of $(_OUTPUTDIR)
and doesn't append "-$(DEBUG_NAME)" to ALT_OUTPUTDIR like so:
COMMON_DEBUG_FLAGS= \
DEBUG_NAME=$(DEBUG_NAME) \
ALT_OUTPUTDIR=$(OUTPUTDIR) \
NO_DOCS=true
We will than always end up with two directories like so:
xxx
xxx-fastdebug
if we used "ALT_OUTPUTDIR=xxx".
"xxx-fastdebug" will always be empty (but needed if I follow your
previous post) so we can remove it after the build. But the user will
get the output in the directory he specified with ALT_OUTPUTDIR and
that seems crucial to me.
What do you think?

Your final paragraph I think is the answer:
"In my eyes, the cleanest solution would be if ALT_OUTPUTDIR would be
honoured
"as is", as the output directory for everything we built, without anything
appended to it. So the developer should be free to choose whatever he wants
as
the output directory. And there should be no additional directories
created."
The ongoing problem has been how to make this work in all cases.
But I'm all for it.
The generally accepted default for an output directory has been a ./build or
./dist directory at the top of the source tree you are building.
With corba, jaxp, jaxws, langtools, hotspot all being independently buildable,
what exactly are you recommending to fix this?

Any comments if this is the right way to do a debug build?
If it works it's fine. I usually just run 'make debug_build', does that not
work?
It works, but it has the problems that I detailed in my first mail.
Did you also read that one?
I may seem that my second mail contained the solution for the first
one, but that's not true, its justa partial workaround for the problem
described in the first one:
