Hey, it gets harder when you run FreeBSD 4.X on a FreeBSD amd64 machine and
have mixed i386/amd64 libs :-( I copy over the amd64 versions of ps etc.
and had to copy over some libs that conflict in names. In-order to get
around placement issues I binary edit them on the fly via sed:
sed -e 's/libkvm/libhvm/g' -e 's/libexec/libhxec/g' -e 's/libsbuf/libhbuf/g'
etc. One thing I just found out was:
and hacked libc's getosreldate & uname to use that stuff. I LD_PRELOAD
my lib of these then pkg_add -r, libtool etc. then just work and think
the are really running on FreeBSD 4.X. I wish if LD_PRELOAD lib's
didn't exist then it would just ignore it versus failing to run. I've made
that change locally. That way I can chroot in chroot without needing
the shims when not needed.
It's a mess. Do you think the libc stuff should have the same type
of over-rides as the uname binary. I think so.
