Follow the QUICKSTART guide found at ltt.polymtl.ca.
At this point, LTTV is installed in the default directory. You may find the lttv executable in /usr/local/bin and the librairies in /usr/local/lib. You will also notice the presence of the convert executable in /usr/local/bin. This tool will be used later to convert from the Linux Trace Toolkit trace format to the LTTV format.
