I originally asked this internally to my HS colleagues but alas no
solution. Any Make gurus out there? ;-)
A further note: the obvious reason for this to fail would be because
defs.make is not processed before launching the buildtree.make sub-make,
but AFAICS it is processed.
Thanks,

If I set HOTSPOT_EXTRA_SYSDEFS in the environment or pass it as a
variable to the top-level make invocation then it works fine and
buildtree.make will see it and use it in the makefiles that it generates.
However, I want to set it in the top-level defs.make based on some other
values. I do that and export it so that submakes will see it - but they
don't: buildtree.make sees HOTSPOT_EXTRA_SYSDEFS as empty.
I've tried setting it using += and := but they both fail to set it for
the sub-make.
Using "make -d" is no help at all as it doesn't show how it evaluates
things (the way sh -x does). :(
Does anybody know how I can set this?
Thanks,
David
