If you require full report forms, the profiled components must be compiled using the performance profiling compiler options (usually, the -p option).
If you are using the imake environment provided with the ChorusOS operating system:
Set the profiling option in the Project.tmpl file to profile the whole project hierarchy
or
Set the profiling option in each Imakefile of the directories to be profiled, to profile only a subset of your project hierarchy.
FPROF=ON
The performance profiling option can be added dynamically by calling make with the compiler profiling option:
% make PROF=-p |
The preceding call must be made in the directory of the program that is to be performance profiled.
