Hi, I am trying to upgrade from Boost 1.73 to Boost 1.76 and down to only one consumer left that will not build. This appears to be an issue with Boost::regex. I noticed this in the Boost 1.76 release notes.. "Regex is now header only except in C++03 mode." Clang defaults to C++14, but I noticed BOOST_REGEX_CXX03 is defined. The project does not specify a particular C++ version so it should be using C++14. The functions below exist in the Boost 1.73 Boost::regex library but not in the 1.76 library. The project in question uses the function regex_match(). Any hints as to how to resolve this? ld: error: undefined symbol: boost::scoped_static_mutex_lock::scoped_static_mutex_lock(boost::static_mutex&, bool)
