With bcc tools' profile, I am getting mostly "[unknown]" in the profile output on my C program. This is, of course, expected because the program symbol are not loaded. However, I am not sure how to properly load the symbols so that "profile" program can pick it up. I have built my program with debug enabled "-g", but how do I load the debug symbols to "profile"?

Please see the DEBUGGING section in bcc profile's manpage:
In your case, since it's a C program, I would recommend compiling with
-fno-omit-frame-pointer.
