[Scons-users] Is their a way to build directly from the .sconsign.dblite file on an incremental build?

Thanks Bill. We’re aware of that option, and we do make use of that. I was just looking for some additional optimizations to skip the actual parsing of the SConstruct files (which, in our builds, takes a significant amount of time).
Matt, thanks for the heads up on the ninja script generation tool. We will definitely look into that further.

No you can't build with only a .sconsign.dblite.
But you can instruct SCons to not scan for implicit dependencies and just use those which are stored in the .sconsign.dblite.
--implicit-deps-unchanged should do it.
Take a look at the manpage.

The goal here is to provide an option for doing very fast incremental builds is the developer knows ahead of time that no dependencies have changed.
