Boost::Xpressive compile puzzle under MinGW

问题 Switching to GCC for the first time, and I'm getting a bit confused by what the compiler is telling me here. Essentially, it's behaving like boost::xpressive::wsregex is not defined (I believe). Here is the relevant code: #include "criterion.h" #include <string> #include <boost/xpressive/xpressive.hpp> //More lines of code omitted here class perlRegex : public regexClass { private: std::wstring regexString; boost::xpressive::wsregex regex; // This is the line complained about public: unsigned

问题 I wanted to do some regular expressions in C++ so I looked on the interwebz (yes, I am an beginner/intermediate with C++) and found this SO answer. I really don't know what to choose between boost::regex and boost::xpressive. What are the pros/cons? I also read that boost::xpressive opposed to boost::regex is a header-only library. Is it hard to statically compile boost::regex on Linux and Windows (I almost always write cross-platform applications)? I'm also interested in comparisons of

Slow performance using boost xpressive

问题 Lately I have being using boost xpressive for parsing files. These files are 10 MB each and there will be several hundred of them to parse. Xpressive is nice to work and clear syntax, but the problems comes with performance. It is incredible how it crawls in debug versions, while in release version it spends more than a whole second per file. I have tested against old plain get_line(), find() and sscanf() code, and it can beat xpressive easily. I understand that type checking, backtracking

How to parse mustache with Boost.Xpressive correctly?

I have tried to write a mustache parser with the excellent Boost.XPressive from the brilliant Eric Niebler . But since this is my first parser I am not familiar with the "normal" approach and lingo of compiler writers and feel a bit lost after a few days of trial&error. So I come here and hope someone can tell me the foolishness of my n00bish ways ;) This is the HTML code with the mustache templates that I want to extract ( http://mustache.github.io/ ): Now <bold>is the {{#time}}gugus {{zeit}} oder nicht{{/time}} <i>for all good men</i> to come to the {007} aid of their</bold> {{country}}.
