%At university of michigan we did a port of cap to the apollo.  Basically, 
%because the libraries are not "just like real unix" because of the neat 
%file system, nm doesn't work.   What you should do is start with a generic 
%BSD build, then define the NOSENDMSG and NORECVMSG (or something like 
%that) so that the cap library can be built.  (Basically sendmsg() et. al. 
%never made it into apollo's tcp libraries)  Do a build & everything should 
%work-- EXCEPT aufs
%
Hm. Things work much better under Domain/OS 10.1. However, just as a small
note - nm works fine on Domain style libraries, it's ar that you have to
fuss with. For situations where you just need to test for the existence
of a routine, nm works fine. (Like for the Configure script that accompanies
rn, patch, and other self-configuring programs...)

Considering that sendmsg() is used with UDP... }-) Actually, all of that
works in 10.x now too. If you want a CAP 5.0 distribution that runs on
Apollos, you should contact Wes Craig here (er, at the Computing Center,
not the Math department.) wes@terminator.cc.umich.edu.

%Basically because of apollos distrbuted file system's root level called 
%"//" instead of "/", aufs will blow up when it tries to assign unique 
%directory IDs to all the paths below.  If i can recall, a few simple 
%changes to "afpdid.c" did the trick, but i'm not quite sure if that was 
%all (we did this over a year ago & we havent looked at it since-- CAP 
%seems to have memory leaks or other errors which seems to leave nasty, 
%un-killable processes around so we didn't officially support it)

Disclaimer - Wes did the work, not me... By the way, CAP 5.0 seems to work
pretty well with UAB on a Sun 4/110 running SunOS 4.01. (I've just been
using lwsrv and aufs.)
