Hi ! > I am looking for a profiler to easily profile a C program of mine > on my Etch box (amd64): any suggestions are welcome. I've recently been using the Google Profiler without problem. It is available as a Debian package (libgoogle-perftools-dev and libgoogle-perftools0) and just works by linking your program against "libprofiler". Note that I've not used it extensively so I cannot swear that it covers everything. cheers, Gregor
