I thought I'd enquire as to whether anyone's thought of migrating the NetBSD
build mechanism to something like Jam or elsewise. What I'm curious about is
not whether it's just too much work, but technical reasons against shifting
focus to another build tool or mechanism.
Perhaps there're a few things that something like Jam doesn't do so well?
The reason I ask is that Jam seems to be orders of magnitude quicker when
building large-ish projects. For example:
Task Sybmake Jam
Full build from scratch 116 min 93 min
Full build with nothing to do 30 min 3 min
Full build after a small change 30 min 9 min
Recompile/relink after small change 10 min 2 min
This was in Sybase and were measurements they took during their conversion to
Jam. Course, the switch itself was extensive, but the gains afterwards made
up for it.
Finally, Jam may be in the process of being tuned to do header file caching as
I write this note, which means that the tool may eventually be much quicker
than it is right now.
Apple appears to like Jam, as they bundle a version of it with Project
Builder--I think mostly because it is under a very BSD-like license which
doesn't preclude making binary-only commercial derivative.
