Hi Ying,
If you look at your command line for some reason scons is trying to
execute 'o' to build that line. I have no idea how it could get 'o'
as the compiler. You can install multiple versions of gcc on your
machine at once and just pass CC= and CXX= options to scons (e.g.
scons build/ALPHA_FS/m5.debug CC=gcc CXX=g++).

Hello everyone,
Because the compatibility problem between M5 2.0b2 and g++4.1, I
uninstalled gcc4.1 and installed gcc4.0.
After the installation of gcc4.0, scons complains like below:
o build/ALPHA_FS/base/annotate.do -c -pipe -fno-strict-aliasing -
Wall -Wno-sign-compare -Werror -Wundef -ggdb3 -O0 -
DTHE_ISA=ALPHA_ISA -DDEBUG -DTRACING_ON=1 -Iext/dnet -I/usr/include/
python2.4 -Ibuild/libelf/include -Ibuild/ALPHA_FS build/ALPHA_FS/
base/annotate.cc
sh: o: command not found
......
I have added the path variable and I can use scons to complie
helloworld.c. My system is fedora core 5. I thought it may because
fedora core deleted some gcc4.1 depentent files and changed some
system settings that M5's compilation needs. Is that ture?
BTW: If I want to use a different version of gcc, can I just remove
the /usr/bin/gcc and make a symbolic link to use gcc4.0 instead of
uninstalling the whole gcc4.1. Like this:
mv /usr/bin/g++ /usr/bin/g++41
ln -s /home/yx/Program/gcc-4.0.3/bin/g++ /usr/bin/g++
Thanks in advance.
