We are building boost 1.68 and are experiencing some issues. It seems the 'arm' override is not set and hence the following assignment is not done in boost.inc and making our linking fail: BJAM_OPTS_append_arm = " abi=aapcs architecture=arm" BOOST_LIBS_append_arm = " context coroutine" We are indeed compiling for arm: TUNE_FEATURES = "arm armv7a vfp thumb neon callconvention-hard so either the boost recipe needs to use another override, or the 'arm' override needs to be set. Further, we would need BOOST_LIBS_append to be extended with 'fiber': BOOST_LIBS_append_<?> = " context coroutine fiber"
