- <h1>Boost.Compatibilty library</h1>
- <p>This library provides workarounds which allow the other Boost
- libraries to be used on otherwise non-conforming platforms. We hope that
- it will be possible to remove this library at some time in the future as
- standard library suppliers become more conforming.</p>
- <h2>Missing C++ standard library CXX headers (e.g <cstdio>)
- workaround</h2>
- <p>The Python script: <tt><a href=
- "generate_cpp_c_headers.py">generate_cpp_c_headers.py</a></tt> creates a
- full set of C++ C header files (e.g. <cstdio>) that are missing on
- some platforms. The header files created by this script reside in the
- directory <tt><a href=
- "../../boost/compatibility/cpp_c_headers/">boost/compatibility/cpp_c_headers</a></tt>.
- To use the header files, add this directory to the include file search
- path. For example:</p>
- <pre>
- cxx -I/usr/local/boost/boost/compatibility/cpp_c_headers ...
- </pre>
- <p>Supported platforms are:</p>
- <ul>
- <li>Compaq Alpha, RedHat 6.2 Linux, Compaq C++ V6.3 (cxx)</li>
- <li>Compaq Alpha, Tru64 Unix V5.0, Compaq C++ V6.2 (cxx)</li>
- <li>Silicon Graphics, IRIX 6.5, MIPSpro Compilers: Version 7.3.1.1m
- (CC)</li>
- </ul>
- <p>There are more powerful alternatives to using the Boost.Compatibility
- library CXX headers, e.g. <a href="http://stlport.sourceforge.net">STLport</a>
- or <a href=
- "http://www.fnal.gov/docs/working-groups/fpcltf/Pkg/ISOcxx/doc/0ISOcxx.html">
- ISOCXX</a>. However, in contrast to these alternatives, the
- <tt>generate_cpp_c_headers.py</tt> script is very light-weight (less than
- 100 non-comment lines of Python code), much less ambitious, significantly
- easier to maintain and therefore more suitable as an interim
- workaround.</p>

- <h2>Missing C++ standard library <limits> header workaround
- <a href="../../boost/limits.hpp">boost/limits.hpp</a></h2>
- <p>Several Boost libraries require the standard library's <limits>
- header, yet this header is not always supplied by non-conforming
- compilers and libraries. Header <a href=
- "../../boost/limits.hpp">boost/limits.hpp</a> simply includes the
- standard library <limits> header if available, otherwise includes
- <a href=
- "../../boost/detail/limits.hpp">boost/detail/limits.hpp</a>.
- BOOST_NO_LIMITS from <a href="../config/config.htm">boost/config.hpp</a>
- is used to determine <limits> availability.</p>
- <p>Note also the test program <a href=
- "../config/test/limits_test.cpp">limits_test.cpp</a></p>
