Bug 311

perf is included in poky, but there are few things needed to make it work/work better - this bug is meant to track the problems until everything is fixed.

The first problem an unresolved library reference:

perf: error while loading shared libraries: libelf.so.1: cannot open shared object file: No such file or directory

The fix, which I'll check in once I'm set up for it, is:

diff --git a/meta/recipes-kernel/linux/linux-wrs_git.bb b/meta/recipes-kernel/li

Thanks to Bruce Ashfield for point out the fix.

The next problem is that 'perf trace -l' shows no scripts, which should be fixed by including all the files copied by 'perf install' e.g. using prefix=/usr should put them in /usr/libexec (note that there may be a perf/tools patch needed to properly handle the new prefix).  Also probably need to install and compile against libperl-dev and python-dev in order to get support for the embedded interpreters.
