Component configuration: - atomic : building - chrono : building - context : not building ... }}} but it still tries to build the context code anyways and fails: {{{ ""x86_64-pc-linux-gnux32-g++"" -x assembler-with-cpp -finline-functions \ -Wno-inline -Wall -fPIC -DBOOST_ALL_NO_LIB=1 -DBOOST_CONTEXT_DYN_LINK=1 \ -DBOOST_CONTEXT_SOURCE -DNDEBUG -I""."" -c -o \ ""bin.v2/libs/context/build/gcc-4.8/gentoorelease/pch-off/threading-multi/asm/jump_i386_sysv_elf_gas.o"" \ ""libs/context/src/asm/jump_i386_sysv_elf_gas.S"" libs/context/src/asm/jump_i386_sysv_elf_gas.S: Assembler messages: libs/context/src/asm/jump_i386_sysv_elf_gas.S:71: Error: operand type mismatch for `jmp' }}} this is because it's trying to build the i386 code instead of the x86_64 code" Bugs closed To Be Determined context Boost 1.55.0 Problem fixed
