Re: [Boost-users] UPDATE rules

I thought that's how Boost.Build always worked.

That *may* be how Boost.Build works. I don't know. I don't use it. I only use BJAM. Version 3.1.18 added these lines to jam.c: if (!targets_to_update()) mark_target_for_updating("all"); Thus, if no target is defined on the command line, it force it to "all." These lines do not exist in 3.1.17.
