What am I doing wrong? First note that gprof is part of binutils and not part of gcc so it'd probably be better to use the binutils mailing list (binutils at sourceware.org) for this. The problem with terminating the program with kill -15 is that the profiling library registers its mcleanup() routine with atexit(), and this is what writes all the data to the gmon.out file. So the app must either return from main() or call exit() in order to get any profile data, it won't happen for a SIGTERM or any other abnormal termination sequence. You might be able to work around this by e.g. installing a signal handler that explicitly calls exit() or something. Or perhaps you could use a different profiling method like oprofile. Brian
