  18     <h1>Boost.Compatibilty library</h1>
  19
  20     <p>This library provides workarounds which allow the other Boost
  21     libraries to be used on otherwise non-conforming platforms. We hope that
  22     it will be possible to remove this library at some time in the future as
  23     standard library suppliers become more conforming.</p>

  25     <h2>Missing C++ standard library CXX headers (e.g &lt;cstdio&gt;)
  26     workaround</h2>
  27
  28     <p>The Python script: <tt><a href=
  29     "generate_cpp_c_headers.py">generate_cpp_c_headers.py</a></tt> creates a
  30     full set of C++ C header files (e.g. &lt;cstdio&gt;) that are missing on
  31     some platforms. The header files created by this script reside in the
  32     directory <tt><a href=
  33     "../../boost/compatibility/cpp_c_headers/">boost/compatibility/cpp_c_headers</a></tt>.
  34     To use the header files, add this directory to the include file search
  35     path. For example:</p>
  36     <pre>
  37 cxx -I/usr/local/boost/boost/compatibility/cpp_c_headers ...
  38 </pre>
  39
  40     <p>Supported platforms are:</p>
  41
  42     <ul>
  43       <li>Compaq Alpha, RedHat 6.2 Linux, Compaq C++ V6.3 (cxx)</li>
  44
  45       <li>Compaq Alpha, Tru64 Unix V5.0, Compaq C++ V6.2 (cxx)</li>
  46
  47       <li>Silicon Graphics, IRIX 6.5, MIPSpro Compilers: Version 7.3.1.1m
  48       (CC)</li>
  49     </ul>
  50
  51     <p>There are more powerful alternatives to using the Boost.Compatibility
  52     library CXX headers, e.g. <a href="http://stlport.sourceforge.net">STLport</a>
  53     or <a href=
  54     "http://www.fnal.gov/docs/working-groups/fpcltf/Pkg/ISOcxx/doc/0ISOcxx.html">
  55     ISOCXX</a>. However, in contrast to these alternatives, the
  56     <tt>generate_cpp_c_headers.py</tt> script is very light-weight (less than
  57     100 non-comment lines of Python code), much less ambitious, significantly
  58     easier to maintain and therefore more suitable as an interim
  59     workaround.</p>

  64     <a href="../../boost/limits.hpp">boost/limits.hpp</a></h2>
  65
  66     <p>Several Boost libraries require the standard library's &lt;limits&gt;
  67     header, yet this header is not always supplied by non-conforming
  68     compilers and libraries.&nbsp; Header <a href=
  69     "../../boost/limits.hpp">boost/limits.hpp</a> simply includes the
  70     standard library &lt;limits&gt; header if available, otherwise includes
  71     <a href=
  72     "../../boost/detail/limits.hpp">boost/detail/limits.hpp</a>.&nbsp;
  73     BOOST_NO_LIMITS from <a href="../config/config.htm">boost/config.hpp</a>
  74     is used to determine &lt;limits&gt; availability.</p>
  75
  76     <p>Note also the test program <a href=
  77     "../config/test/limits_test.cpp">limits_test.cpp</a></p>
