Be certain that the PTP/CDT/FDT plugin is installed and running properly in your eclipse installation. Use Tau's perfdmf_configure utility to set up a performance database for Eclipse to store profile output.

Run the install_plugins.sh script located in [tau installation]/tools/src/eclipse with the location of your eclipse installation. e.g: ~/tau2/tools/src/eclipse/install_plugins.sh /opt/eclipse

Restart eclipse with the -clean flag after installing the plugins.

In eclipse go to the Window menu, select Preferences and go to the Tau preferences section. If the PTP is available the TAU section will be under the PTP menu. Enter the location of the desired architecture directory in your Tau installation in the Tau Arch Directory field.
