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.
Are you defining BOOST_REGEX_RECURSIVE? That would force it into legacy-mode.
The functions below exist in the Boost 1.73 Boost::regex library but not in the 1.76 library.
Hmm, that's strange, do you have a test case? We do test C++03 legacy mode in CI, so this should all still be working, plus nothing should actually have changed in those classes compared to 1.73.
