| <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> |
