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?
