Re: [Gems-users] Simics 4.0 for GEMS?

[Greg Byrd <gbyrd@xxxxxxxx>]

For the record, I have not been able to get GEMS to work 
"just fine" with Simics 3.x.  The main issue is the versions 
of compilers used to compile and link GEMS vs. what's used 
for Simics.
I know others have had success, but my experience has not 
been good.  I was hoping to make the move to 3.0 for my 
class this semester, but I ended up sticking with 2.x.
So I'm unhappy to see 2.x go away, but I understand why and 
hopefully will figure out a way to work around it.

PS.  I found the right mix of compilers to get everything to 
link, but then ruby0.init crashes immediately with a bad 
address passed to free().  If anyone has seen similar 
behavior and figured out a fix, let me know.  I'm somewhat 
constrained by a university computing environment that's 
largely out of my control, so please don't send me fixes 
like "reinstall Linux with this patch."
