Boost.Build - msvc-stlport toolset

###  | # Boost.Build ## vc7-stlport toolset

## Introduction

Boost.Build's vc7-stlport toolset supports the Microsoft Visual C++ .NET command-line tools, using the STLport standard library implementation on Microsoft Windows. It is designed to allow you to build and test with multiple installed versions of STLPort, so that objects build in each configuration will be built into separate directories.

## Configuration Variables

The `vc7-stlport` toolset responds to the following variables, which can be set in the environment or configured on the jam command-line using `-sVARIABLE_NAME=`value. It is an extension of the msvc-stlport toolset and therefore responds to all of the MSVC configuration variables in addition to those listed below.

In the table below, version corresponds to an STLPort version number, e.g. "`4.5.3`".

Variable Name | Semantics | Default | Notes
--- | --- | --- | ---
`STLPORT_PATH` | A directory containing at least one subdirectory of the form `/STLPort-`version where an STLPort installation can be found. | empty | Allows easy configuration for an installation where several STLPort versions are installed under a single directory.
`STLPORT_`version`_PATH` | The directory where the specific STLPort version installation can be found, in case there is no central location appropriate for `STLPORT_PATH`, above, or a particular version's installation is not located in the usual place. | empty | Allows configuration of a specific STLPort installation.
`STLPORT_VERSION` | The version of STLPort in use by default. | `4.6` | Other values can be selected in parallel setting the build property <stlport-version> to values from the list of `$(STLPORT_VERSIONS)`
`STLPORT_VERSIONS` | A space-separated list of alternate versions of STLport available on this machine. | `4.6 4.5 4.0`

## Toolset-Specific Features

The following vc7 `-stlport`-specific features can be used in target build requirements or in the `BUILD` variable:

Feature | Values | Default | Semantics
--- | --- | --- | ---
`native-wchar_t` | `off on` | `off` | Controls whether wchar_t is an intrinsic type or not. This is off by default since that's the way STLPort builds itself. Turning this on may result in unresolved externals from STLPort, unless you rebuild STLPort with /Zc:wchar_t.
`stlport-version` | `$(STLPORT_VERSION) $(STLPORT_VERSIONS)` (see above) | `$(STLPORT_VERSION)` | Selects a version of STLPort for each target
`stlport-cstd-namespace` | `std global` | `std` | Controls whether or not names from the "C" library headers such as <cstdlib> are imported into `namespace std`.
