boost::regex (implementation question)
Yesterday I downloaded boost v1.71.0 The file 'regex/v4/cregex.hpp' contains declarations for functions like 'regexecA' and 'regexecW'. There are similar declarations for regfree, regcomp & regerror. But where are the implementations for those functions? Or is my own app expected to provide them? Many thanks, John Emmas

You would find them under libs/regex/src, but those old POSIX API's while technically still supported have been deprecated for a long time. John.

Many thanks John, I do remember building boost::regex from source (maybe back around the time of boost v1.54) but the source files from back then won't compile against the latest regex headers. Also... I'm not seeing a 'src' subfolder here in v1.71 (for that matter, I don't even see a 'boost/libs/' subfolder). These are the subfolders I currently see under 'boost/regex':- config pending v4 Have I maybe downloaded the wrong version? (or am I looking in the wrong place??) John

I would think not!

Not under boost-root/boost, but under boost-root/libs/regex.

Thanks again John... it's all building fine now (it turned out I WAS looking in the wrong place !! ) John
