Boost release 1.56.0 beta 1 is now available from SourceForge

I'm experiencing problems cross-compiling Boost 1.56.0b1 (host Linux Mint 17 x86_64, target x86_64-w64-mingw32), and I think this is due to the build system not picking up my user-config.jam. In Boost 1.55.0, I placed my user-config.jam in /tools/build/v2, and it worked. In Boost 1.56.0b1 this directory no longer exists, so I tried placing my user-config.jam in /tools/build and in /tools/build/example where the example user-config.jam is located. Neither of these seem to work, i.e. the invoked compiler is the native compiler g++ and not the cross-compiler specified in user-config.jam.

Try putting user-config.jam into tools/build/src and see if it finds it there. If not, you can run b2 —debug-configuration and it will output where it searches for user-config.jam (and other components). — Noel
