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.
I do not see that anywhere in the project in question and checking to see if that is defined it does not appear to be the case.
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.
No. I can give you access to my system if you want to take a look around.
