I'm sorry for forgetting describe the building in detail. The building
succeed except checking tcmalloc failed.

You can get a 12% performance improvement by installing tcmalloc
(libgoogle-perftools-dev package on Ubuntu or RedHat).

Hi,
My os is Ubuntu 10.04 x86_64. And libgoogle-perftools-dev can't be
installed from official repository because of depend problems on
ubuntu 10.04, so I have to compile it myself.
I think I install libgoogle-perftools successfully because ldconfig
can locate those libs and 'gcc -ltcmalloc' also succeed.

What's more, I write a simple scons script to check tcmalloc_minimal
and this script succeed too.
env = Environment()
conf = env.Configure()
if conf.CheckLib('tcmalloc_minimal'):
print "true"
However, when I try "scons build/ALPHA_MOESI_CMP_directory/gem5.opt",
tcmallc checking still failed.
