I am new to Ubuntu. I follow the instruction from http://sourceware.org/systemtap/wiki/SystemtapOnUbuntu that is necessary to install SystemTap on Ubuntu.
I lost in Step 4.
How can i run step 4: ?
Setp 4: sudo apt-get install elfutils
, for eu-readelf Then run this script as root, whenever you install additional debug symbols
for file in `find /usr/lib/debug -name '*.ko' -print`
do
buildid=`eu-readelf -n $file| grep Build.ID: | awk '{print $3}'`
dir=`echo $buildid | cut -c1-2`
fn=`echo $buildid | cut -c3-`
mkdir -p /usr/lib/debug/.build-id/$dir
ln -s $file /usr/lib/debug/.build-id/$dir/$fn
ln -s $file /usr/lib/debug/.build-id/$dir/${fn}.debug
done
This makes available the module probes available and is friendly to other debug symbol savvy apps like gdb and oprofile. This convention should make it's way into Ubuntu in the near future.
