It's getting a little more magic every day to generate a.out stuff,
but not all that bad. Basically I built lib/csu/i386, gnu/lib/libgcc,
lib/libc and libexec/rtld-aout, in order, with these settings:
NOMAN=yup DESTDIR="" OBJFORMAT=aout MAKEOBJDIRPREFIX=/usr/obj/aout
In each directory, I used make obj, make, make install. (By the way,
there are a lot of twisty little passages in /usr/share/mk. One of
them required me to add DESTDIR="", which should be a NOP.)
The generated ld.so has bloated a bit :-) but works fine. So we could
in principle build ld.so for every release. It's just a question of
whether we should. I think we should. But it might be just as easy
to copy it off the 3.3 CD every time. It's dead end stuff after all.
Does the release engineer have an opinion?
Stephen.
