Well, I’ve taken my first steps towards understanding the gnu ‘make’ utility thanks to Andrew Oram and Steve Talbott. I’ve hacked together Makefiles before (we use quite a lot of them in our code base), but tonight I said ‘No more hackery! Makefiles deserve some attention!’. So I read the first few chapters and successfully fixed my vision debugger’s Makefile to handle profiling with gprof, gnu’s profiling utility. I’ll post our (offline) vision system’s profile results when I get them.
