No need for you to worry about command line parameters. Uncheck -pg, (I
never use that), go to Options/Libraries, check "Link for profiling", go to
the Compile menu, choose Link (to force linking for the first time after
checking this option). Run your program (it's profiling while you run). When
you have finished the profile run, exit your program, exit rhide and type
"gprof myexe.exe > outnam.txt". This will dump the profile data collected in
myexe.exe to the text file outnam.txt. Just open outnam.txt with your
favorite text editor, and there's your profile data.
