Docs for running 32-bit apps?

All this stuff has been said before on this list, but I'll try to pull
it together here in a coherent summary.
To recap, this is 6.0-RELEASE amd64 running on Intel SBX82 Systems.
Rebuilding/installing world (or build32/install32) is sufficient to
Note KERNCONF=GENERIC includes:
options COMPAT_43 # Needed by COMPAT_LINUX32
options COMPAT_IA32 # Compatible with i386 binaries
options COMPAT_FREEBSD4 # Compatible with FreeBSD4
options COMPAT_FREEBSD5 # Compatible with FreeBSD5
options COMPAT_LINUX32 # Compatible with i386 linux binaries
Note also that "WITH_LIB32=yes" in make.conf is not required (anymore,
see other threads on this list).
After install32, I had to run 'ldconfig -32 /usr/lib32'.
I still have plenty of apps that don't find the versions of libraries
they want. I'm mostly handling this with /etc/libmap32.conf (see
== /etc/libmap32.conf ==
I believe this is roughly equivalent to the method noted (but not
recommended) by Steve of adding symlinks. It worked fine for the test
program I don't have the source for (yeah!).
The c++ test program, which is my own code, did not work with either a
libstdc++.so.3 mapping in /etc/libmap32.conf or by copying the
libstdc++.so.3 from the 4.9-RELEASE machine it was compiled on. But
it compiles fine - so no worries there.
Those are my results, your mileage will vary.
p.s. Steve, thanks for the pointers.
