Is CLOCK_THREAD_CPUTIME_ID a macro on this platform? I would prefer to check if CLOCK_THREAD_CPUTIME_ID is defined and use it. Would it be the correct behavior?
Yes, is defined like: #define CLOCK_THREAD_CPUTIME_ID 3 in time.h. Vicente Botet wrote:
could you try this patch
// chrono/config.hpp
# if defined(_POSIX_THREAD_CPUTIME) && !defined(BOOST_DISABLE_THREADS) # define BOOST_CHRONO_HAS_THREAD_CLOCK # define BOOST_CHRONO_THREAD_CLOCK_IS_STEADY true # endif # if defined(CLOCK_THREAD_CPUTIME_ID) && !defined(BOOST_DISABLE_THREADS) # define BOOST_CHRONO_HAS_THREAD_CLOCK # define BOOST_CHRONO_THREAD_CLOCK_IS_STEADY true # endif
This causes compilation error because BOOST_CHRONO_THREAD_CLOCK_IS_MONOTONIC is undefined in chrono/thread_clock.hpp: BOOST_CHRONO_STATIC_CONSTEXPR bool is_monotonic = BOOST_CHRONO_THREAD_CLOCK_IS_MONOTONIC; However following patch works for me: # if defined(_POSIX_THREAD_CPUTIME) && !defined(BOOST_DISABLE_THREADS) # define BOOST_CHRONO_HAS_THREAD_CLOCK # define BOOST_CHRONO_THREAD_CLOCK_IS_MONOTONIC true # endif # if defined(CLOCK_THREAD_CPUTIME_ID) && !defined(BOOST_DISABLE_THREADS) # define BOOST_CHRONO_HAS_THREAD_CLOCK # define BOOST_CHRONO_THREAD_CLOCK_IS_MONOTONIC true # endif I'm not sure about BOOST_DISABLE_THREADS.

On Android works fine for me. BR, Libor -- View this message in context: http://boost.2283326.n4.nabble.com/chrono-Thread-clock-compatibility-problem... Sent from the Boost - Dev mailing list archive at Nabble.com.
