Hello

I tried upgrading from 1.55 to 1.56 and got a linking error.

I am using mingw32-gcc-4.7.2 on windows 7. I compiled boost with "b2 toolset=gcc stage release -j8 --build-type=complete link=static threading=multi variant=release"

..\..\..\lib/libPrimeGameEngineRelease.a(GameEngine.o):GameEngine.cpp:(.text$_ZN5boost6detail5win3223GetTickCount64emulationEv+0x27): undefined reference to `_InterlockedCompareExchange' ..\..\..\lib/libPrimeGameEngineRelease.a(GameEngine.o):GameEngine.cpp:(.text$_ZN5boost6detail5win3223GetTickCount64emulationEv+0x87): undefined reference to `_InterlockedCompareExchange'

Static libraries cannot link anything. If you use a static library, in the absence of autolink pragmas, the onus is on you to link whatever is needed by the libraries. In this case, you in your project appear to not be linking in the library defining InterlockedCompareExchange, which IIRC is located in Kernel32.lib.

Release 1.56.0 of the Boost C++ Libraries is now available.

These open-source libraries work well with the C++ Standard Library, and are usable across a broad spectrum of applications. The Boost license encourages both commercial and non-commercial use.

This release contains one new library and numerous enhancements and bug fixes for existing libraries.

=== Modularization === Boost version control has migrated to a system using git submodules. This shouldn't make too much of a difference to users, although the directory structure is now a bit different.

Parts of some libraries have been moved into different modules, and several new modules have been extracted from existing code. All header paths should remain the same. The new modules are:

• Assert: Customizable assert macros. Maintained by Peter Dimov. • Core: Core utilities used by other libraries, with minimal dependencies. Maintained by Peter Dimov, Glen Fernandes and Andrey Semashev. • Lexical_Cast: General literal text conversions, such as an int represented a string, or vice-versa, from Kevlin Henney. • Throw_Exception: A common infrastructure for throwing exceptions from Boost libraries, from Emil Dotchevski. • Winapi: Windows API declarations without , for internal Boost use.

=== New Libraries === • Align: Memory alignment functions, allocators, and adaptors, from Glen Fernandes. • Type_Index: Runtime/Compile time copyable type info, from Antony Polukhin.
