And there are at least two different ways to use the Boost libraries:

1. Using Boost.Build to build your own projects, link against "un-installed" libraries that are automatically built on demand and updated when the Boost sources and/or libraries change.

2. Using whatever build system you like (including possibly Boost.Build), link against the versions you've installed using bjam --install

Method 2 is mostly for people who don't want to use Boost.Build for their own projects, or who want to share prebuilt Boost library images among several Boost developers.

There's also:

3. Don't use Boost.Build (or bjam) at all! Include the appropriate Boost files in your project and compile them like your custom code.

This would minimize the chances of the Boost code getting compiled with incompatible options from your custom code.

1. also minimizes those chances, and it doesn't have the disadvantage that you might build with options that are incompatible with the Boost library code you're using. -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
