You need to link with Boost.System which should have been compiled for arm64 as well. HTH Le 05/07/2021 à 18:18, simsicon via Boost-users a écrit :

Hi,

I was following the tutorial (https://www.boost.org/doc/libs/1_76_0/doc/html/boost_asio/tutorial/tuttimer1... https://www.boost.org/doc/libs/1_76_0/doc/html/boost_asio/tutorial/tuttimer1...) on macbook with m1 chip, and try to run the simple code and I meet the following error:

Undefined symbols for architecture arm64:   "boost::chrono::steady_clock::now()", referenced from: boost::asio::detail::chrono_time_traitsboost::chrono::steady_clock >::now() in mock-93ab24.o ld: symbol(s) not found for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

I am kind of new to C++ and boost, but I think this issue may be related to apple silicon compatibility? --

Thanks&Best Regards

Zhang Zheng
