+ 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="sect1" lang="en" xml:lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="manual.intro.setup.prereq"></a>Prerequisites</h2></div></div></div><p>
+ Because libstdc++ is part of GCC, the primary source for
+ installation instructions is
+ <a class="ulink" href="http://gcc.gnu.org/install/" target="_top">the GCC install page</a>.
+ In particular, list of prerequisite software needed to build the library
+ <a class="ulink" href="http://gcc.gnu.org/install/prerequisites.html" target="_top">
+ 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="ulink" href="ftp://sources.redhat.com/pub/binutils" target="_top">
+ 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>
+ 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 3.2.1 and later, this
+ means that glibc 2.2.5 or later is required and the "C"
+ library de_DE locale information must be installed.
+ </p><p>
+ Note however that the sanity checks involving the de_DE
+ locale are skipped when an explicit --enable-clocale=gnu
+ configure option is used: only the basic checks are carried
+ out, defending against misconfigurations.
+ </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 the underlying "C" library locale
+ information installed will mean that C++ named locales for the
+ above regions will not work: because of this, the libstdc++
+ testsuite will skip the named locale tests. If this isn't an
+ issue, don't worry about it. If named locales are needed, the
+ underlying locale information must be installed. Note that
+ rebuilding libstdc++ after the "C" locales are installed is not
+ necessary.
