This section describes how to install Boost.Build from a released Boost source distribution or CVS image.  All paths are given relative to the Boost.Build v2 root directory, which is located in the tools/build/v2 subdirectory of a full Boost distribution. 
To install Boost.Jam, copy the executable, called bjam or bjam.exe to a location accessible in your PATH. Go to the Boost.Build root directory and run bjam --version. You should see:
Boost.Build V2 (Milestone N) Boost.Jam xx.xx.xx
where N is the version of Boost.Build you're using.
If you are using Boost's CVS state, be sure to rebuild bjam even if you have a previous version. The CVS version of Boost.Build requires the CVS version of Boost.Jam.
When bjam is invoked, it always needs to be able to find the Boost.Build root directory, where the interpreted source code of Boost.Build is located. There are two ways to tell bjam about the root directory:
At the root directory of your project or in any of its parent directories, create a file called boost-build.jam, with a single line:
boost-build /path/to/boost.build ;
N.B. When bjam is invoked from anywhere in the Boost directory tree other than the Boost.Build root and its subdirectories, Boost.Build v1 is used by default. To override the default and use Boost.Build v2, you have to add the --v2 command line option to all bjam invocations.
If you're planning to package Boost.Build for a Linux distribution, please follow these guidelines:
Create a separate package for Boost.Jam.
Create another package for Boost.Build, and make this package install all Boost.Build files to /usr/share/boost-build directory. After install, that directory should contain everything you see in Boost.Build release package, except for jam_src directory. If you're using Boost CVS to obtain Boost.Build, as opposed to release package, take everything from the tools/build/v2 directory. For a check, make sure that /usr/share/boost-build/boost-build.jam is installed.
Placing Boost.Build into /usr/share/boost-build will make sure that bjam will find Boost.Build without any additional setup.
Provide a /etc/site-config.jam configuration file that will contain:
using gcc ;
You might want to add dependency from Boost.Build package to gcc, to make sure that users can always build Boost.Build examples.
If those guidelines are met, users will be able to invoke bjam without any explicit configuration.
 Note that packages prepared for Unix/Linux systems usually make their own choices about where to put things and even which parts of Boost to include. When we say “released source distribution” we mean a distribution of Boost as released on its SourceForge project page.
 The Boost.Build subset of boost is also distributed separately, for those who are only interested in getting a build tool. The top-level directory of a Boost.Build distribution contains all the subdirectories of the tools/build/v2 subdirectory from a full Boost distribution, so it is itself a valid Boost.Build root directory. It also contains the tools/jam/src subdirectory of a full Boost distribution, so you can rebuild Boost.Jam from source.
