I'm pleased to announce that the next milestone release of Boost.Build V2 is available at     http://prdownloads.sourceforge.net/boost/boost-build-2.0-m12.tar.bz2     http://prdownloads.sourceforge.net/boost/boost-build-2.0-m12.zip See also     http://boost.org/boost-build2/ for online docs (a copy is included in distribution). Changes in this release: - The Pathscale, PGI and mipspro compilers are now supported. - Support for autoconfiguration of toolset based on command-line toolset=xxxx request, and for default toolset configuration as a fallback. - Support for precompiled headers for gcc toolset, and improvements for msvc. - Mechanism for removing inherited requirements. - The 'make' rule support specifying usage-requirements. - New 'project.extension' rule for declaring standalone projects. - New 'conditional' convenience rule. - New 'glob-tree' rule. - The 'glob' rule accepts patterns to exclude. - Inline targets are now marked explicit automatically. - Toolsets can now implicitly add requirements to all targets. - New 'generate' rule. - The executables produced by the 'run' rule are automatically removed after run. - The gcc toolset uses the version obtained by running the compiler, if no explicit one is provided. - The sun toolset now supports the 'address-model' feature, and uses -KPIC for shared libraries. - Free features on command line affect all targets, not just 'directly requested' ones. Documentation changes: - Installation instructions for Linux distributors. - Configuration options for all supported C++ compilers are now documented. The following bugs were fixed: - The 'cflags' and 'linkflags' now work on Darwin.o - The intel toolset now works on Windows. - Fix library search options for CodeWarriour toolset. - The <install-source-root> could cause duplicate mkdir commands. - Numerious fixes in Boost autolink support - Numerious fixes in Boost.Python support. - Indirect properties not evaluated in usage requirements. - Generator that returns a property set but not target is considered successful. - On Darwin, when several compiler versions are configured, -fcoalesce-templates is applied only to versions that need it. - Volodya -- Vladimir Prus http://vladimir_prus.blogspot.com Boost.Build V2: http://boost.org/boost-build2
