Re: Errors after Swarm install on LinuxPPC

[Darren Schreiber]

Good News - gdb is running.  This was one of the main problems with 
my Linux install that had led me to try unsuccessfully and update 
swarm.

I think that the problems are still installation related based upon 
my use of gdb.  When I run the Cocktail model, it says it can't find 
SwarmEnvironment.m and I confirmed by hand that the file is not in 
fact in place.  My suppostition is that either these files were not 
correctly installed or that they are no longer required and yet 
something thinks they are.

As far as compiling heatbugs, I am getting this complaint about the 
syntax of the Makefile.  I don't see anything odd about it and it 
looks like the syntax of other Makefiles I have.  I cut out the "ifeq 
... endif" stuff from the Makefile and changed the include to 
/usr/etc... instead of the $(SWARMHOME)/... stuff.  It still didn't 
compile correctly.  The error reported was "no target specified."

Thanks for the continuing help.  I can't wait to simply be writing code again.
