I'm primarily a Windows developer, but like to be able to test locally on both Windows and Linux so I don't have to wait for Boost's regression tests to cycle. For several years I've done that on a Linux virtual machine. I just rebuilt my virtual machine and kept a log so I could share how it is done. Such a virtual machine is free and is easy enough that most Boost library maintainers who use Windows could do the setup in an afternoon, most of which is just downloading files, and can be overlapped with other work. See https://svn.boost.org/trac/boost/wiki/StartTestingLinuxOnWindows Corrections or other comments appreciated. Enjoy! --Beman PS: The process would work in the other direction too, but it would require a Windows license (I.E. not free) and I don't have experience going in that direction so can't write about it.
