| 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>. |
| Additional data is given here only where it applies to libstdc++. |
| </p><div class="sect2" lang="en" xml:lang="en"><div class="titlepage"><div><div><h3 class="title"><a id="build.prereq"></a>Prerequisites</h3></div></div></div><p> |
| The list of software needed to build the library is kept with the |
| rest of the compiler, at |
| <a class="ulink" href="http://gcc.gnu.org/install/prerequisites.html" target="_top"> |
| http://gcc.gnu.org/install/prerequisites.html</a>. The same page |
| also lists the tools you will need if you wish to modify the source. |
| </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 if 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. |
