...
but it couldn't pass the compile, error was: [C++ Error] trim.hpp(233): E2285 Could not find a match for 'detail::trim_end(undefined,undefined,detail::is_classifiedF)' [C++ Error] trim.hpp(126): E2285 Could not find a match for 'detail::trim_begin(undefined,undefined,detail::is_classifiedF)'
... I'm not sure what the problem could be. But it seems like some bug in a compiler.
So my first question is: What compiler do you use?
BCB. I checked and it fails with 6.4 (the latest).
