Re: help getting started

Thanks for your help, Paul... nothing works so far, but you are very
generous to suggest some things.

THanks for the ref.  I *was* trying to make libffi work.

I do have an O2 with IRIX 6.3 like he mentioned...
I might have to try to figure out what code changes he had to make to
get it to compile.  I wonder if Benedikt's distribution could be published
along with the other binary+source?

Believe me, I tried it.
Marcus compiled it for Irix 5.3.  I have 5.3 machines here, but GCC 2.7.2.2
is only available for them with a bunch of provisos and needing a bunch
of patches, so I grabbed the Irix 6.2 version of GCC.  Then I got
Marcus' 5.3 binary version of swarm and tried to compile the tutorial on
my IRIX 6.2 machine using the IRIX 6.2 version of GCC.

That gives me errors that objc_malloc and objc_free are unresolved.
I tried explicitly adding the path for libobjc.a on the compile line,
but it doesn't make any difference.
