   6    and properly built binaries useful for linking to other software is
   7    a multi-step process. Steps include getting the sources,
   8    configuring and building the sources, testing, and installation.
   9    </p><p>The general outline of commands is something like:
  10    </p><pre class="programlisting">
  11    <span class="emphasis"><em>get gcc sources</em></span>
  12    <span class="emphasis"><em>extract into gccsrcdir</em></span>
  13    mkdir <span class="emphasis"><em>gccbuilddir</em></span>
  14    cd <span class="emphasis"><em>gccbuilddir</em></span>
  15    <span class="emphasis"><em>gccsrcdir</em></span>/configure --prefix=<span class="emphasis"><em>destdir</em></span> --other-opts...
  16    make
  17    make check
  18    make install
  19    </pre><p>
  20      Each step is described in more detail in the following sections.
  21    </p><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="manual.intro.setup.prereq"></a>Prerequisites</h2></div></div></div><p>
  22   Because libstdc++ is part of GCC, the primary source for
  23    installation instructions is
  24    <a class="link" href="http://gcc.gnu.org/install/" target="_top">the GCC install page</a>.
  25    In particular, list of prerequisite software needed to build the library
  26    <a class="link" href="http://gcc.gnu.org/install/prerequisites.html" target="_top">
  27    starts with those requirements.</a> The same pages also list
  28    the tools you will need if you wish to modify the source.
  29 </p><p>
  30    Additional data is given here only where it applies to libstdc++.
  31   </p><p>As of GCC 4.0.1 the minimum version of binutils required to build
  32       libstdc++ is <code class="code">2.15.90.0.1.1</code>.
  33       Older releases of libstdc++ do not require such a recent version,
  34       but to take full advantage of useful space-saving features and
  35       bug-fixes you should use a recent binutils whenever possible.
  36       The configure process will automatically detect and use these
  37       features if the underlying support is present.
  38    </p><p>
  39      To generate the API documentation from the sources you will need
  40      Doxygen, see <a class="link" href="documentation_hacking.html" title="Writing and Generating Documentation">Documentation
  41      Hacking</a> in the appendix for full details.
  42    </p><p>
  43    Finally, a few system-specific requirements:
  44    </p><div class="variablelist"><dl class="variablelist"><dt><span class="term">linux</span></dt><dd><p>
  45           If GCC 3.1.0 or later on is being used on GNU/Linux, an attempt
  46           will be made to use "C" library functionality necessary for
  47           C++ named locale support.  For GCC 4.6.0 and later, this
  48           means that glibc 2.3 or later is required.
  49         </p><p>
  50           If the 'gnu' locale model is being used, the following
  51           locales are used and tested in the libstdc++ testsuites.
  52           The first column is the name of the locale, the second is
  53           the character set it is expected to use.

  76 </pre><p>Failure to have installed the underlying "C" library
  77       locale information for any of the above regions means that
  78       the corresponding C++ named locale will not work:  because of
  79       this, the libstdc++ testsuite will skip named locale tests
  80       which need missing information.  If this isn't an issue, don't
  81       worry about it.  If a named locale is needed, the underlying
  82       locale information must be installed.  Note that rebuilding
  83       libstdc++ after "C" locales are installed is not necessary.
  84       </p><p>
