and properly built binaries useful for linking to other software is
a multi-step process. Steps include getting the sources,
configuring and building the sources, testing, and installation.
</p><p>The general outline of commands is something like:
</p><pre class="programlisting">
<span class="emphasis"><em>get gcc sources</em></span>
<span class="emphasis"><em>extract into gccsrcdir</em></span>
mkdir <span class="emphasis"><em>gccbuilddir</em></span>
cd <span class="emphasis"><em>gccbuilddir</em></span>
<span class="emphasis"><em>gccsrcdir</em></span>/configure --prefix=<span class="emphasis"><em>destdir</em></span> --other-opts...
make
make check
make install
</pre><p>
Each step is described in more detail in the following sections.
</p><div class="section" title="Prerequisites"><div class="titlepage"><div><div><h2 class="title"><a id="manual.intro.setup.prereq"/>Prerequisites</h2></div></div></div><p>
Because libstdc++ is part of GCC, the primary source for
installation instructions is
<a class="link" href="http://gcc.gnu.org/install/" target="">the GCC install page</a>.
In particular, list of prerequisite software needed to build the library
<a class="link" href="http://gcc.gnu.org/install/prerequisites.html" target="">
starts with those requirements.</a> The same pages also list
the tools you will need if you wish to modify the source.
</p><p>
Additional data is given here only where it applies to libstdc++.
</p><p>As of GCC 4.0.1 the minimum version of binutils required to build
libstdc++ is <code class="code">2.15.90.0.1.1</code>. You can get snapshots
(as well as releases) of binutils from
<a class="link" href="ftp://sources.redhat.com/pub/binutils/" target="">
ftp://sources.redhat.com/pub/binutils</a>.
Older releases of libstdc++ do not require such a recent version,
but to take full advantage of useful space-saving features and
bug-fixes you should use a recent binutils whenever possible.
The configure process will automatically detect and use these
features if the underlying support is present.
</p><p>
To generate the API documentation from the sources you will need
Doxygen, see <a class="link" href="documentation_hacking.html" title="Writing and Generating Documentation">Documentation
Hacking</a> in the appendix for full details.
</p><p>
Finally, a few system-specific requirements:
</p><div class="variablelist"><dl><dt><span class="term">linux</span></dt><dd><p>
If gcc 3.1.0 or later on is being used on linux, an attempt
will be made to use "C" library functionality necessary for
C++ named locale support. For gcc 4.6.0 and later, this
means that glibc 2.3 or later is required.
</p><p>
If the 'gnu' locale model is being used, the following
locales are used and tested in the libstdc++ testsuites.
The first column is the name of the locale, the second is
the character set it is expected to use.

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