Since we just had a release, should be re-visit moving all the mandatory source code into a separate directory together? For the newbies, this means changing the BOOST_ROOT . libs .. date_time ... src .. graph ... src into something like BOOST_ROOT . src .. date_time .. graph Right now, using mandatory source files means scrambling into a lot of directories figuring out what to add. There is stuff like Boost-Build, but it doesn't work for everyone, and I feel that it's a "cute" overkill solution. No matter the plan there are some caveats: 1. Some platforms require some libraries to be put in separate DLLs. 2. You have to exclude the driver files from Boost-Test, since each includes a "main" function. (And if you actually are doing testing, then you know that you can include at most one driver file.) Besides the caveats, you can just dump all the mandatory source code into your IDE's project file (or make file) and don't worry Boost-Build. If some source needs to be in a DLL, then start a sub-project. (If you don't need a library at all, then exclude it from the project to save compile time. The linker will tell you, by choking, if you went too far.) -- Daryle Walker Mac, Internet, and Video Game Junkie darylew AT hotmail DOT com
