The get-invocation-command rule executes a shell command then return the output, or the user provided value if the execution did not output anything. However, it means that the user cannot overwrite the tools paths and has to manually patch the toolset file to hardcode the tool path, which is an issue. The easy fix would be to check for an option before calling get-invocation-command (at least in gcc.jam, but it is possible that other toolsets are also affected). A maybe-not-so-easy-fix would be to change get-invocation-command behavior to return the user provided value if there is one, and to call the specified command if there is none (so the opposite of what is currently done). tl;dr : '''tools/build/v2/user-config.jam''' {{{ using clang : 3.3 : /home/arcanis/emscripten/emcc : ""/home/arcanis/emscripten/archiver"" ""/home/arcanis/emscripten/emranlib"" ; }}} Doesn't (cannot) work " Bugs new To Be Determined Building Boost Boost 1.55.0 Problem
