Chapter 3. Libraries and Runtime Support

3.3.2. The GNU C++ Standard Library

The libstdc++ package contains the GNU C++ Standard Library, which is an ongoing project to

implement the ISO 14882 Standard C++ library.

Installing the libstdc++ package will provide just enough to satisfy link dependencies (i.e. only

shared library files). To make full use of all available libraries and header files for C++ development,

you must install libstdc++-devel as well. The libstdc++-devel package also contains a GNU-

specific implementation of the Standard Template Library (STL).

As the C++ language and runtime implementation has remained stable throughout Red Hat Enterprise

Linuxes 4, 5, and 6, no compatibility libraries are needed for libstdc++. However, combatability

libraries compat-libstdc++-296 for Red Hat Enterprise Linux 2.1 and compat-libstdc++-33

for Red Hat Enterprise Linux 3 are provided for support.

3.3.2.1. GNU C++ Standard Library Updates

The Red Hat Enterprise Linux 6 version of the GNU C++ Standard Library features the following

improvements over its Red Hat Enterprise Linux 5 version:

• Added support for elements of ISO C++ TR1, namely:

• <tr1/array>

• <tr1/complex>

• <tr1/memory>

• <tr1/functional>

• <tr1/random>

• <tr1/regex>

• <tr1/tuple>

• <tr1/type_traits>

• <tr1/unordered_map>

• <tr1/unordered_set>

• <tr1/utility>

• <tr1/cmath>

• Added support for elements of the upcoming ISO C++ standard, C++0x. These elements include:

• <array>

• <chrono>

• <condition_variable>

• <forward_list>

• <functional>

• <initalizer_list>
