As a curiosity, I'll note that the project-root.jam created by "bootstrap.bat gcc" contains a "using msvc ;" and not "using gcc ;", which seems wrong to me.
bootstrap.bat sets msvc unconditionally. The language for batch scripts is really horrible, so working this out correctly is likely to be very painful.
It is a horrible language that I know quite well. If you write the pseudo-code, I can translate it into command script for you.
In tools/v2/build/engine/build.bat: if --guess-toolset in $argv call :Guess_Toolset return $BOOST_JAM_TOOLSET Also, make sure that local variables don't escape. I don't know how to pass the return value through setlocal. (I just noticed this in bootstrap.bat: REM Ideally, we should obtain the toolset that build.bat has REM guessed. However, it uses setlocal at the start and does not REM export BOOST_JAM_TOOLSET, and I don't know how to do that REM properly. Default to msvc for now.) in bootstrap.bat: TOOLSET = find argument --with-toolset=xxx if not $TOOLSET set TOOLSET=`tools/build/v2/engine/build.bat --guess-toolset` In Christ, Steven Watanabe
