Re: [Boost-users] Having trouble including my static library(whichuses regex) in my MFC app

Thanks John,

With regards to your comment:
---------------------------------------------------------------
Apologies, but ignore everything in my last message: you can
work around this quite easily by building the regex lib
without /Zc:wchar_t, or by adding the line:

template<> _CRTIMP2 std::size_t __cdecl char_traits<unsigned
short>::length(unsigned short const*);

to the end of the other specializations in usinstances.cpp
(this is the fix that's going into cvs any minute now).
----------------------------------------------------------------

I cannot compile my MFC app in Multibyte, it must be in Unicode, also
when I use wchar_t as built in type I get other link errors. So, I'm
trying to attempt building the regex lib without the /Zc:wchar_t as you
have suggested. But I'm not sure how to do this. Can you please help me?

Thanks,
Martin
