Hi, I tried to update and recreate links to headers today and stumbled into this: $ b2 headers Unable to load Boost.Build: could not find build system. --------------------------------------------------------- /home/lastique/src/boost/boost-build.jam attempted to load the build system by invoking 'boost-build tools/build/src ;' but we were unable to find "bootstrap.jam" in the specified directory or in BOOST_BUILD_PATH (searching /home/lastique/src/boost/tools/build/src, /usr/share/boost-build). Please consult the documentation at 'http://www.boost.org'. Also, bootstrap.sh also seems to be not working: $ ./bootstrap.sh ./bootstrap.sh: 1: ./bootstrap.sh: ./tools/build/src/engine/build.sh: not found Building Boost.Build engine with toolset ... Failed to build Boost.Build build engine Consult 'bootstrap.log' for more details bootstrap.log contains: ./bootstrap.sh: 218: cd: can't cd to ./tools/build/src/engine I remember there were discussions about moving Boost.Build somewhere, and it appears that some scripts were updated for that but the actual Boost.Build code is still in tools/build/v2. I did 'git pull' in the Boost root, it's up to date.
