This section describes how to install Boost.Build from a released source distribution. 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.
