This is mostly a bugfix release to account for issues impacting Boost Libraries. There is one "big" change though. It can be rather difficult to find build failures when running larger builds. To facilitate figuring out problems the brief summary output at the end of a build is now less brief. It now includes a sorted list of the targets that got skipped and failed. The output of those lists mirrors the general skipped/failed items. Hence it's possible to search for the same strings in the rest of the output quickly.

  • New: Add listing of failed and skipped targets to end of build summary to make it easier to find what fails.
    -- René Ferdinand Rivera Morell
  • New: Add mpi.run-flags to mpi toolset that allows for arbitrary flags applied to running mpi targets. This allows, for example, adding --oversubscribe flag to make it possible to run tests where the tasks are more than the nodes available.
    -- René Ferdinand Rivera Morell
  • Fix spurious errors when the header scanning tries to scan empty file names.
    -- René Ferdinand Rivera Morell
  • Make C/C++/ObjC include directive scanning pattern more strict to avoid trying to scan for empty file names.
    -- Andrey Semashev
  • Fix mingw linker commands to always replace backslashes with forward slashes.
    -- Christian Seiler
  • Fix QCC debug build flag. The QCC toolset was using an old, no longer supported, debug symbols option.
    -- John McFarlane

This is a new era in B2. The drive of this new major version is to move the core build system from being implemented in Jam to C++. This initial release is only a start in this move by having some minimal aspects implemented in C++ using a new Jam/C++native binding system. Even though this is a major release, the goal is to still have backward compatibility for existing project build files. But that backward compatibility is not guaranteed for other Jam files.

  • New: Support for Jam native variant values of string (original Jam value type), number (floating point numbers), and object (instances of classes).
    -- René Ferdinand Rivera Morell
  • New: Port modules class, errors, modules, regex, set, string, and sysinfo to C++.
    -- René Ferdinand Rivera Morell
  • New: Port bootstrap.jam to C++ and instead use build-system.jam as key file to find build files.
    -- René Ferdinand Rivera Morell
  • New: Add require-b2 builtin rule to verify the B2 version a particular Jam file needs.
    -- René Ferdinand Rivera Morell
  • New: Add regex.grep builtin that does parallel (where available) file content search with regex matching.
    -- René Ferdinand Rivera Morell
  • New: Make parts of internals thread safe to support parallel built-ins. Currently includes Jam values, hash tables, and filesystem.
    -- René Ferdinand Rivera Morell
  • New: Add import-search project rule to declare additional search paths for import that refer to searched project locations, or other directories.
    -- René Ferdinand Rivera Morell
  • Fix consistent use of OPT_SEMAPHORE and documentation of JAM_SEMAPHORE.
    -- Thomas Brown
  • Fix archive actions failing for mingw.
    -- René Ferdinand Rivera Morell

IMPORTANT: Building B2 with VisualStudio 2013, i.e. MSVC 12, is no longer supported or tested. The effort to engineer workarounds for the missing C++11 features became too much. And was taking away from other improvements.

  • Fix crash on some platforms/compilers from invalid garbage reads of varargs
