It seems the gprof option -pg is still there, but it does not work. What are the plans for this feature?
What else can be used as profiler for fpc?

On which OS? It's known not to work on Linux currently (for the same reason that shared library initialization doesn't work).

Callgrind/Cachegrind is probably your best bet (and more detailed than gprof).

Has the '-pg' (gprof) compiler option issues ever been resolved under Linux?
After running my application the gprof.out file is only 186 bytes big with no profiling information.

I' not sure, but I don't think so. Under Linux, you can however also use valgrind with the cachegrind backend for profiling (but in this case ensure that your program and the units you want to profile are compiled with -gv, and that none of the used units is compiled with plain -g/-gl)

Thanks Jonas.... I'm trying 'valgrind' now. Just reading up on what information is stored in the generate text output file I've now go. Only thing I can guess so far is that big numbers are bad. :-)
