<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>
