Building B2

Installing B2 after building it is simply a matter of copying the generated executables someplace in your PATH. For building the executables there are a set of build bootstrap scripts to accomodate particular environments. The scripts take one optional argument, the name of the toolset to build with. When the toolset is not given an attempt is made to detect an available toolset and use that. The build scripts accept these arguments:

build [toolset]

Running the scripts without arguments will give you the best chance of success. On Windows platforms from a command console do:

cd jam source location
.\build.bat

On Unix type platforms do:

cd jam source location
sh ./build.sh

For the Boost.Jam source included with the Boost distribution the jam source location is BOOST_ROOT/tools/build/src/engine.

If the scripts fail to detect an appropriate toolset to build with your particular toolset may not be auto-detectable. In that case, you can specify the toolset as the first argument, this assumes that the toolset is readily available in the PATH.

	Note
	The toolset used to build Boost.Jam is independent of the toolsets used for Boost.Build. Only one version of Boost.Jam is needed to use Boost.Build.

The supported toolsets, and whether they are auto-detected, are:

Notes:

If VCVARSALL.BAT is called to set up the toolset, it is passed all the extra arguments, see below for what those arguments are. This can be used to build, for example, a Win64 specific version of b2. Consult the VisualStudio documentation for what the possible argument values to the VCVARSALL.BAT are.

The built executables are placed in a subdirectory specific to your platform. For example, in Linux running on an Intel x86 compatible chip, the executables are placed in: "bin.linuxx86". The =b2[.exe]= executable can be used to invoke Boost.Build.

The build scripts support additional invocation arguments for use by developers of Boost.Jam and for additional setup of the toolset. The extra arguments come after the toolset:

Arguments not in the form of an option, before option arguments, are used for extra setup to toolset configuration scripts.
Arguments of the form "--option", which are passed to the build.jam build script.
Arguments not in the form of an option, after the options, which are targets for the build.jam script.

build [toolset] [setup*] [--option+ target*]

The arguments immediately after the toolset are passed directly to the setup script of the toolset, if available and if it needs to be invoked. This allows one to configure the toolset ass needed to do non-default builds of b2. For example to build a Win64 version with vc8. See the toolset descriptiona above for when particular toolsets support this.

The arguments starting with the "--option" forms are passed to the build.jam script and are used to further customize what gets built. Options and targets supported by the build.jam script:

---: Empty option when one wants to only specify a target.
--release: The default, builds the optimized executable.
--debug: Builds debugging versions of the executable. When built they are placed in their own directory "bin./platform/.debug".
--grammar: Normally the Jam language grammar parsing files are not regenerated. This forces building of the grammar, although it may not force the regeneration of the grammar parser. If the parser is out of date it will be regenerated and subsequently built.
--with-python=path: Enables Python integration, given a path to the Python libraries.
--gc: Enables use of the Boehm Garbage Collector. The build will look for the Boehm-GC source in a "boehm_gc" subdirectory from the b2 sources.
--duma: Enables use of the DUMA (Detect Unintended Memory Access) debugging memory allocator. The build expects to find the DUMA source files in a "duma" subdirectory from the b2 sources.
--toolset-root=path: Indicates where the toolset used to build is located. This option is passed in by the bootstrap (build.bat or build.sh) script.
--show-locate-target: For information, prints out where it will put the built executable.
--noassert: Disable debug assertions, even if building the debug version of the executable.
dist: Generate packages (compressed archives) as appropriate for distribution in the platform, if possible.
clean: Remove all the built executables and objects.
