This is exactly the argument that got us into our current build-tools mess. We've always placed so much emphasis on making things easy for Boost *developers* that we've made them extremely tough for Boost *users*. This feature---the ability to run "bjam" once and run everything across multiple compilers---is responsible for the majority of the damage, because we've been architecting bjam for multiple compilers at the expense of the common case of a single system compiler. Have you tried helping a Boost newbie go through the process of building and installing Boost lately? It's extremely painful, but we don't see that pain because we've all gone through the initial hurdles of getting bjam setup just right for our own configurations. That's the wrong thing to optimize: we need to optimize for the case where a new user downloads Boost and wants to build/use it immediately. Those users only care about a single compiler---the one they use for their day-to-day work---and would greatly benefit from being able to use their platform-specific tools (Visual Studio, xCode, whatever). If we're going to go through the effort of introducing a new build system, we need to focus on the user experience first and foremost. - Doug _______________________________________________ Boost-cmake mailing list Boost-cmake@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-cmake
