[erlang-questions] Parallel Make in OTP
Fri Dec 18 15:14:38 CET 2009
I agree that the GoogleCode T-Build stuff is clunky. I'm revising
T-Build at the moment, and I'm dissatisfied with it. I'm confident
that I can scan for dependencies using a single Makefile, and not have
to resort to the weird nested include files. T-Build is too complex.
All a project should need is one Makefile.
At the moment, adding new applications to a build means inserting
symlinks, so it's not entirely hands-free. I want the Makefile to be
immutable, capable of scanning for additions, deletions, and
-include*(). dependencies (although that may still require a bit of
Bash voodoo under the covers). As long as the project directory
structure is similar, it should all Just Work. I'm aiming for zero
Makefile maintenance, which I believe is desirable regardless which
build system is used.
I've heard many suggestions of replacements for Make, but a lot of
them don't have any difference or enhancement that warrants jumping
ship. Most seem to be changes in style more than in substance (but
someone prove me wrong, please).
Apart from Sinan, maybe. But I've not looked at it hard enough.
Considering the "old school" methods and process that we use in
T-Mobile, Sinan's agile style is also a leap in culture which, I found
from experience in the Previous Place, is much harder to push in a
On a tangent: What if a declarative, rules based system was available
in Erlang (someone's going to tell me there is one, for sure!), what
other projects besides a drop-in replacement for a parallel,
distributed Make could be made possible?
