   7    and properly built binaries useful for linking to other software is
   8    a multi-step process. Steps include getting the sources,
   9    configuring and building the sources, testing, and installation.
  10    </p><p>The general outline of commands is something like:
  11    </p><pre class="programlisting">
  12    <span class="emphasis"><em>get gcc sources</em></span>
  13    <span class="emphasis"><em>extract into gccsrcdir</em></span>
  14    mkdir <span class="emphasis"><em>gccbuilddir</em></span>
  15    cd <span class="emphasis"><em>gccbuilddir</em></span>
  16    <span class="emphasis"><em>gccsrcdir</em></span>/configure --prefix=<span class="emphasis"><em>destdir</em></span> --other-opts...
  17    make
  18    make check
  19    make install
  20    </pre><p>
  21      Each step is described in more detail in the following sections.
  22    </p><div class="sect1" title="Prerequisites"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="manual.intro.setup.prereq"></a>Prerequisites</h2></div></div></div><p>
  23   Because libstdc++ is part of GCC, the primary source for
  24    installation instructions is
  25    <a class="ulink" href="http://gcc.gnu.org/install/" target="_top">the GCC install page</a>.
  26    In particular, list of prerequisite software needed to build the library
  27    <a class="ulink" href="http://gcc.gnu.org/install/prerequisites.html" target="_top">
  28    starts with those requirements.</a> The same pages also list
  29    the tools you will need if you wish to modify the source.
  30 </p><p>
  31    Additional data is given here only where it applies to libstdc++.
  32   </p><p>As of GCC 4.0.1 the minimum version of binutils required to build
  33       libstdc++ is <code class="code">2.15.90.0.1.1</code>. You can get snapshots
  34       (as well as releases) of binutils from
  35       <a class="ulink" href="ftp://sources.redhat.com/pub/binutils/" target="_top">
  36       ftp://sources.redhat.com/pub/binutils</a>.
  37       Older releases of libstdc++ do not require such a recent version,
  38       but to take full advantage of useful space-saving features and
  39       bug-fixes you should use a recent binutils whenever possible.
  40       The configure process will automatically detect and use these
  41       features if the underlying support is present.
  42    </p><p>
  43    Finally, a few system-specific requirements:
  44    </p><div class="variablelist"><dl><dt><span class="term">linux</span></dt><dd><p>
  45           If gcc 3.1.0 or later on is being used on linux, an attempt
  46           will be made to use "C" library functionality necessary for
  47           C++ named locale support.  For gcc 3.2.1 and later, this
  48           means that glibc 2.2.5 or later is required and the "C"
  49           library de_DE locale information must be installed.
  50         </p><p>
  51           Note however that the sanity checks involving the de_DE
  52           locale are skipped when an explicit --enable-clocale=gnu
  53           configure option is used: only the basic checks are carried
  54           out, defending against misconfigurations.
  55         </p><p>
  56           If the 'gnu' locale model is being used, the following
  57           locales are used and tested in the libstdc++ testsuites.
  58           The first column is the name of the locale, the second is
  59           the character set it is expected to use.

  82 </pre><p>Failure to have the underlying "C" library locale
  83       information installed will mean that C++ named locales for the
  84       above regions will not work: because of this, the libstdc++
  85       testsuite will skip the named locale tests. If this isn't an
  86       issue, don't worry about it. If named locales are needed, the
  87       underlying locale information must be installed. Note that
  88       rebuilding libstdc++ after the "C" locales are installed is not
  89       necessary.
