Hi there,

what actually do you do? If you do something like:

cc -c -p anyname.c
cc anyname.o

things go wrong, because ld needs to resolve symbol `mcount' 
but can't find it. You need /usr/lib/mcrt0.o.
Better still, use:

cc -p anyname.o 

it automatically includes this lib. (-p flag)

read cc(1), prof(1), monitor(3).

See ya!
