Re: [Swarm-Support] OSX

[Bill Northcott]

Your compile log has loads of warnings.  These are the result of problems 
with GNU libtool 1.4.x.  Version 1.5 has just been released and should fix 
these once it is incorporated into Swarm.  They are only warnings and are 
not breaking the link.

The link breaks because of the undefined symbol _main which is of course 
the main function in your program, not anything from a Swarm library.

That would normally happen because the order on the link line is wrong. 
This may also be a libtool issue.  It may also be because there was some 
problem building main.o.

If you would like to send the source code to me off the list, I will try 
to compile it.
