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> 24 25 <h2>Missing C++ standard library CXX headers (e.g <cstdio>) 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. <cstdio>) 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> 37cxx -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> 60 61 <p>Contributed by Ralf W.
