Build
Because libstdc++ is part of GCC, the primary source for
installation instructions is
the GCC install page.
Additional data is given here only where it applies to libstdc++.
Prerequisites
The list of software needed to build the library is kept with the
rest of the compiler, at
http://gcc.gnu.org/install/prerequisites.html. The same page
also lists the tools you will need if you wish to modify the source.
As of GCC 4.0.1 the minimum version of binutils required to build
libstdc++ is 2.15.90.0.1.1
. You can get snapshots
(as well as releases) of binutils from
ftp://sources.redhat.com/pub/binutils.
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.
Finally, a few system-specific requirements:
linux
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.
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.
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.

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.
To install support for locales, do only one of the following:
install all locales
with RedHat Linux:
export LC_ALL=C
rpm -e glibc-common --nodeps
rpm -i --define "_install_langs all"
glibc-common-2.2.5-34.i386.rpm
Instructions for other operating systems solicited.
install just the necessary locales
with Debian Linux:
Add the above list, as shown, to the file
/etc/locale.gen
run /usr/sbin/locale-gen
on most Unix-like operating systems:
localedef -i de_DE -f ISO-8859-1 de_DE
(repeat for each entry in the above list)

Make
If you have never done this before, you should read the basic
GCC Installation
Instructions first. Read all of them.

When building libstdc++ you'll have to configure
the entire gccsrcdir directory. The full list of libstdc++
specific configuration options, not dependent on the specific compiler
release being used, can be found here.
Consider possibly using --enable-languages=c++ to save time by only
building the C++ language parts.
