Re: [Boost-users] building boost::regex lib with mingw from gnu/linux

I had lots of trouble compiling boost from mingw/linux.  Instead, lower 
yourself to windows for an hour or so and compile with mingw/win32. 
Then use the libraries you have compiled under linux.

Your problem below stems from the fact that mingw does not currently 
support wide characters.  There is probably a #define-guard that isn't 
properly set because you are compiling from linux, and its probably 
picking up the gcc capabilities from native-gcc, not mingw-gcc.
