Hello,
I just started using M5. I am trying to compile the beta3. It gives
the following output:

scons: Building targets ...
It does run thru and build finally, but hy does it not find the options
file? Is that required?
It's just a standard notification the first time you build in a new
directory... it didn't find any saved build options from the last time
you built (since there was no last time), so it's initializing the saved
options with the default values. If this was actually an error it would
say "error" or something like that.

Also, I cannot build anything other than the debug. If I try opt on
either FS or SE it gives:
scons build/ALPHA_SE/m5.opt

Using saved options file

scons: *** Error converting option: CPU_MODELS
Invalid value(s) for option: <built-in function all>
File "SConstruct", line 611, in <module>
It looks like it's having problems reloading the saved options... I'm
guessing this is just because it's the second time you've tried to build
something, and not anything to do with opt vs debug etc. What version
of scons do you have? ("scons -v") I don't see this problem with v0.96.92.
