Linux Tools Project/OProfile/User Guide

Getting Started

The OProfile plug-in requires a little extra set up compared to other Eclipse plug-ins. However, it only takes a few simple steps. After the plug-in is first installed, running most profile-related commands will bring up a dialog similar to the following:

As the dialog suggests, you must run the supplied install script to allow the plug-in to perform OProfile tasks as root (since OProfile can not be run as an unprivileged user). The steps below are the same as the dialog but described in more detail.

Step 1 - Locate Plug-in Installation Directory

Open up a terminal and locate the scripts directory. The install script is located in the org.eclipse.linuxtools.oprofile.core plug-in directory, but this directory can be in a few places:

• If you are using a distro-supplied version of Eclipse and installed the plug-in via the update site, it will most likely be under the ~/.eclipse directory, hence try the command

find ~/.eclipse -name 'org.eclipse.linuxtools.oprofile.core_*'

• Alternatively, if you are using an extracted tarball of Eclipse (ie: you downloaded a .tar.gz from here) then the plug-in will most likely be in the plugins sub-directory of where you extracted it. Let's say you extracted the tarball to /home/ksebasti, so your Eclipse installation would be in /home/ksebasti/eclipse, then try the command

find /home/ksebasti/eclipse -name 'org.eclipse.linuxtools.oprofile.core_*'

Note that the quotes (') and asterisk (*) are necessary. Example output is something like this:

$ find /home/ksebasti/eclipse -name 'org.eclipse.linuxtools.oprofile.core_*'

/home/ksebasti/eclipse/plugins/org.eclipse.linuxtools.oprofile.core_0.2.0.200904131051

Then, change the sub-directory natives/linux/scripts of this plug-in directory:

cd /home/ksebasti/eclipse/plugins/org.eclipse.linuxtools.oprofile.core_0.2.0.200904131051/natives/linux/scripts

Step 2 - Choose Which Installation Script To Run
