Thanks, that was indeed the problem. Unfortunately when I add the O3CPU to the scons command, m5 no longer properly compiles. I used the command:
% scons build/ALPHA_FS/m5.fast CPU_MODELS=AtomicSimpleCPU,TimingSimpleCPU,O3CPU
and scons terminates with:
/usr/bin/g++-3.4 -o build/ALPHA_FS/cpu/o3/base_dyn_inst.fo -c -pipe -fno-strict-aliasing -Wall -Wno-sign-compare -Werror -Wundef -O3 -DTHE_IS A=ALPHA_ISA -DNDEBUG -Iext/dnet -I/usr/include/python2.4 -Ibuild/libelf/include -Ibuild/ALPHA_FS build/ALPHA_FS/cpu/o3/base_dyn_inst.cc

scons: building terminated because of errors.
I haven't had any compilation problems with any of the other configurations. This occurs both when trying to compile the full system and syscall emulation modes. Have you experienced this?
Thanks again,
James
Hi James,
The problem is that the detailed model is not included in the models being compiled by default. Normally we only compile the AtomicSimpleCPU and TimingSimpleCPU models. When compiling M5, try adding "CPU_MODELS=AtomicSimpleCPU,TimingSimpleCPU,O3CPU' to the scons command.
For example:
% scons build/ALPHA_SE/m5.debug CPU_MODELS=AtomicSimpleCPU,TimingSimpleCPU,O3CPU
That tells scons which CPU models to compile. Sorry about the confusion, and I'll add this to the FAQ.

Subject: [m5-users] Example detailed mode configuration bug
Hi all,
After downloading, compiling, and setting up m5 to run in the full system mode, I tried to boot the simulator in the detailed mode with:
./m5.fast -d output/ configs/example/fs.py -d
and I get the following error:
M5 compiled Sep 1 2006 17:35:27
M5 started Tue Sep 5 14:08:08 2006
M5 executing on idealjames
command line: ./m5.fast -d output/ configs/example/fs.py -d
panic: Simulator object type 'DerivO3CPU' not found.
@ cycle 0
[createObject:build/ALPHA_FS/sim/builder.cc, line 121]
Program aborted at cycle 0
Aborted
Note that the system boots perfectly with the -t (for timing mode) or with no argument (atomic mode). I found the Deriv03CPU class within the src/python/m5/objects directory and attempted to setup symlinks to see if this was simply a path error of some sort, but I have never used Python before and didn't have much luck. I have also installed the latest patch for m5 beta 2.
I also posted this as a bug in the "Flyspray" bug tracker linked off of the website (I noticed I was the first, is this up and running yet?).
Thanks
