Re: swarm-2002-05-14 compilation error

[Paul E Johnson]

Comedy: to uninstall swarm, remove the directory into which you 
installed it!  If you are building and installing for a single system, 
make configure line have --prefix=/home/blah/blah/swarm

so you can tell where all the swarm stuff is and eliminate it.

If you don't do that, then you are on your own when uninstall time comes.

That's why I use rpms, because they are easy to uninstall.  If you build 
2.1.1 and installed into /usr or something, then you have a mess because 
your files are scattered all around, especially if your configure line 
did not have "enable-subdirs" or such.


Now, I see you are using gcc-3.2 and I don't have a Marcus-style patch 
for that to make Swarm compile. As far as I know, no Swarmer has 
announced any workability with 3.2.  I still use the patched version of 
3.0.4.

You could do a useful service for me and the Hive in general if you 
would hack one part of the swarm source and then compile/install swarm, 
and then let me know if it works.

It could be gcc-3.2 introduces new problems we have not heard of. But I 
know of at least one thing that will for-sure not work if you have gcc 
"off the shelf."

The part you need to hack is this one line in Swarm's file interface.el. 
You need to insert the semicolon before the line 
(load-dispatch-hash-table protocol phase ht).

That line is in there now because it takes advantage of some special 
optimization that Marcus Daniels did for gcc-objc, but if you are using 
the garden variety gcc, it can't handle that optimization in Swarm, and 
so it could cause an error.

This change is equivalient to reversing this patch:


*** interface.el-original       Sun Jul  8 19:22:33 2001
--- interface.el        Sun Jul  8 19:22:56 2001

      ht))
