| 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"> |
| <em class="replaceable"><code>get gcc sources</code></em> |
| <em class="replaceable"><code>extract into gccsrcdir</code></em> |
| mkdir <em class="replaceable"><code>gccbuilddir</code></em> |
| cd <em class="replaceable"><code>gccbuilddir</code></em> |
| <em class="replaceable"><code>gccsrcdir</code></em>/configure --prefix=<em class="replaceable"><code>destdir</code></em> --other-opts... |
| make |
| make check |
| make install |
| </pre><p> |
| Each step is described in more detail in the following sections. |
| </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> |
| Because libstdc++ is part of GCC, the primary source for |
| installation instructions is |
| <a class="link" 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="link" 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>. |
| 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 class="variablelist"><dt><span class="term">linux</span></dt><dd><p> |
| If GCC 3.1.0 or later on is being used on GNU/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. |
| </p><p> |
| To install support for locales, do only one of the following: |
