Hi, I'm looking at a source forge project with the following required libraries: 1) Boost version 1.39 or later 2) TBB (Threading Building Blocks) version 2.1 or later 3) MSM (Meta State Machine) version 1.2 or later 4) Boost Logging Library v2 #3 appears to be in the boost sandbox Does boost sandbox still exists? Boost Sandbox When boost was developed using subversion, the Boost Sandbox contained unreviewed code that is intended to eventually become a part of the Boost libraries. New libraries should be developed separately as https://svn.boost.org/trac/boost/wiki/ModularBoost git modules, and existing projects should be https://svn.boost.org/trac/boost/wiki/ExtractSandbox moved to GitHub. The sandbox remains as a historical record. Accessing the Boost Sandbox The Boost Sandbox lives at https://svn.boost.org/svn/boost/sandbox https://svn.boost.org/svn/boost/sandbox within the old Boost Subversion repository. Regards Oran
