Hi All, Recently we upgraded to Boost 1.82.0. We compiled the boost as : ./bootstrap.sh --with-libraries=filesystem,system,program_options,iostreams,log,regex,stacktrace,thread --without-icu When we tried to use the regex library and build Avro product we are getting following error: Boost/boost_1_82_0/include/boost/regex/v4/cpp_regex_traits.hpp:1117: undefined reference to `boost::scoped_static_mutex_lock::scoped_static_mutex_lock(boost::static_mutex&, bool)' Please can you help us in addressing the issue. Thanks and Regards, Prabhakar
