I just released version 1.3 of RudeBuild, my unity/bulk C++ build tool for Visual Studio 2008-2012. Check out the release notes and download information at http://www.martinecker.com/rudebuild/version-1-3-released/

For those not familiar with the tool, here's a description:

RudeBuild is a non-intrusive bulk/unity C++ build tool that seamlessly integrates into Visual Studio 2008, 2010, and 2012 as an add-in. It can speed up build times of large C++ projects by a factor of 5 or more. RudeBuild also supports the use of IncrediBuild to speed up your build times even more.

RudeBuild comes in two flavors, as a command-line tool that works on Visual Studio solution files and as a Visual Studio add-in complete with toolbar and menus.

When used as an add-in the toolbar acts and looks just like the regular build toolbar but behind the scenes a bulk/unity build of C++ projects is triggered, automatically combining the .cpp files into unity files in a cache location and running devenv to build the modified solution/project. Using RudeBuild in this manner is transparent to the developer and requires no modification to the original source code or project files whatsoever given that the codebase is bulk/unity build-safe. Being bulk/unity-build safe means that there are no symbols with the same name in two different translation units. For example, it is invalid to have a static function called GetFileTime in both File1.cpp and File2.cpp.

The command line version of RudeBuild is useful for automated builds, for example on build servers. A solution file, build configuration and optionally a project name must be specified on the command line.
