[[bbv2.reference.tools.compiler.cw]]
= Code Warrior

The `cw` module support CodeWarrior compiler, originally produced by
Metrowerks and presently developed by Freescale. B2 supports
only the versions of the compiler that target x86 processors. All such
versions were released by Metrowerks before acquisition and are not sold
any longer. The last version known to work is 9.4.

The module is initialized using the following syntax:

----
using cw : [version] : [c++-compile-command] : [compiler options] ;
----

This statement may be repeated several times, if you want to configure
several versions of the compiler.

If the command is not specified, B2 will search for a binary
named `mwcc` in default installation paths and in PATH.

The following options can be provided, using
_`<option-name>option-value syntax`_:

`cflags`::
Specifies additional compiler flags that will be used when compiling C
sources.

`cxxflags`::
Specifies additional compiler flags that will be used when compiling C++
sources.

`compileflags`::
Specifies additional compiler flags that will be used when compiling both C
and C++ sources.

`linkflags`::
Specifies additional command line options that will be passed to the linker.

`setup`::
  The command that sets up environment variables prior to invoking the
  compiler. If not specified, `cwenv.bat` alongside the compiler binary
  will be used.
`compiler`::
  The command that compiles C and C++ sources. If not specified, `mwcc`
  will be used. The command will be invoked after the setup script was
  executed and adjusted the PATH variable.
`linker`::
  The command that links executables and dynamic libraries. If not
  specified, `mwld` will be used. The command will be invoked after the
  setup script was executed and adjusted the PATH variable.
