Thanks David.
That was I did at first. You know I compiled perf from git repository
and it is actually not an official version. So I copy all stuffs in
the directory of perf to
/usr/src/linux-header3-3.10.9-031009/tools/perf and make a soft link
to /usr/bin/perf.
I read the perf-script.py, actually, and set the environment variable
PERF_EXEC_PATH in /etc/profile :
export PERF_EXEC_PATH=
/usr/src/linux-header3-3.10.9-031009/tools/perf
But it doesn't work. But after I use the absolute directory, it seems
to work now. But setting absolute directory still doesn't work on
Redhat 6.0, even if I replaced the total directory of perf.
Here it is. I get a Segmentation fault here.
