That being the case, why doesn't jam "know how to make > libcppunit.so" when it's clearly in the tree? Your impression is unfortunately incorrect. The current Jam system can only build targets in the current directory or subdirectories. I critized this behavior as a side note on this list earlier. It can be fixed, but not without changing Jambase. Anyway, it is not too bad, as you can pass the target you want to build to the jam command invoked in the tree's root directory. CU, Ingo
