7.20. boost

Updated boost packages that fix several bugs are now available for Red Hat Enterprise Linux 6.
The boost packages contain a large number of free peer-reviewed portable C++ source libraries. These libraries are suitable for tasks such as portable file-systems and time/date abstraction, serialization, unit testing, thread creation and multi-process synchronization, parsing, graphing, regular expression manipulation, and many others.

Bug Fixes

When compiling a C++ program using the Boost.MPI library, the compiling process previously failed to find the "boost::mpi::environment::environment(bool)" symbol and terminated with an "undefined reference" error. This update adds the missing symbol, and the described compiling process now successfully creates an executable.
Previously, the boost packages could use packages for different architectures as their dependencies, which in some cases led to a variety of problems with the functionality of the Boost clients. With this update, dependency declarations specify the architecture of the package where relevant, and all packages necessary for correct operation of the Boost clients are downloaded properly.
BZ#1167383, BZ#1170010
Prior to this update, a number of Boost libraries were not compatible with the GNU Compiler Collection (GCC) provided with Red Hat Developer Toolset. A fix has been implemented to address this problem, and the affected libraries now properly work with Red Hat Developer Toolset GCC.
Users of Boost are advised to upgrade to these updated packages, which fix these bugs.
