hardware: samsung s3c6410 after updated to latest poky, the boost compile fail!
error info: libs/atomic/src/lockpool.cpp:127:5: error: 'thread_fence' is not a member of 'boost::atomics::detail' libs/atomic/src/lockpool.cpp:138:5: error: 'signal_fence' is not a member of 'boost::atomics::detail' after dig into it, I found that: the marco 'BOOST_ATOMIC_FLAG_LOCK_FREE' is 0, so it don't include 'operations_lockfree.hpp' which has 'thread_fence' and 'signal_fence', but pthread.h at line 21. in file 'caps_gcc_atomic.hpp', 'BOOST_ATOMIC_FLAG_LOCK_FREE' is set to '0', the author think if '__GCC_ATOMIC_BOOL_LOCK_FREE' is 1, the atomic serial function gcc provided is not lock free. at the end of 'caps_gcc_atomic.hpp', it defined 'BOOST_ATOMIC_THREAD_FENCE' as 2. so the conflict is: *BOOST_ATOMIC_THREAD_FENCE* and *BOOST_ATOMIC_FLAG_LOCK_FREE* I don't know it is the new poky problem, or the boost problem, any idea?
