Makefile profiling

Question

So I have this Makefile based build system that my users feel is working too slowly. For the sake of this question lets define performance as the time it takes make to figur

Answer 1

There have been a couple efforts to add profiling to GNU make. See for example https://github.com/eddyp/make-profiler

My recent entry foray into this has been to extend remake to output information using the valgrind callgrind format; then either kcachegrind or gprof2dot can be used for visualization. Right now, check out the profiling branch in github. Or see this kcachegrind screenshot.

It is all still a work in progress, any help would be appreciated. Help can be things like how to capture things better — there is a lot of information — or how to notate it better in the callgrind format, as well improving what gets the C code doing the profiling. So you don't necessarily have to be a C programmer to help out.
