Re: Errors after Swarm install on LinuxPPC

[Darren Schreiber]

Below, I have pasted what I did and what I got.  In the FAQ, I think 
I found an answer to the errors that I was getting:

        2.3 Big Ugly GCC/Egcs warnings when compiling Swarm applications

	ANSWER. These are annoying but harmless errors that are 
caused by a little glitch in the
	objective-c compiler in the gcc project (which some systems 
have installed
	as egcs). On the SFI web site there is a patch for this that 
users can apply to gcc and
        recompile it. Then recompile swarm itself. Look here:
	ftp://ftp.santafe.edu/pub/swarm/required-software/diffs/objc.diff. 
RPMs compiled with this
	patched compiler will not give this error message either. If 
you use such
        an RPM, there is no need to patch your gcc.

But, this answer doesn't seem to match the results below.  I get a 
segmentation fault and the program simply won't run.  This program 
was running consistently on Windows machines with Swarm 2.1.1.  I 
will go back and see if heatbugs and others run.

Now, if I need to patch the compiler, I have no idea how to do that. 
And, my guess is that .diff files are for Window.

Also, how exactly do I find the application directory (or its linux 
equivalent) and what text do I add to the Makefile to set SWARMHOME 
correctly?  I know I have done this before, but it was long ago and 
maybe I never did it in Linux.  The FAQ says:

        2.4

	You can tell Swarm to use that home either by editing the 
Makefile in the application
        directory (that's my personal favorite)
