This is the configuration on Mac actually: Host type: x86_64-apple-darwin15.6.0 Special build flags: build=release std-regex warnings use-aspell use-hunspell Bundled libraries: boost mythes C++ Compiler: c++ -stdlib=libc++ (8.0.0) C++ Compiler flags: -Wall -Wextra -Os -std=c++14 -Wno-deprecated-register C++ Compiler user flags: -I/Users/Shared/LyX/utilities/include -arch x86_64 -mmacosx-version-min=10.7 -std=c++14 -std=c++11 If I’m not mistaken this means LyX on Mac is using std::regex.
