Same with boost::xpressive:

const boost::xpressive::sregex re_escape_text = boost::xpressive::sregex::compile("([\\^\\.\\$\\|\\(\\)\\[\\]\\*\\+\\?\\/\\\\])");

std::string regex_escape(std::string text){
    text = boost::xpressive::regex_replace( text, re_escape_text, std::string("\\$1") );
    return text;
}
