Hi all,

I need some C help : I want to create a macro that will expand to char* string or wchar_t* string, depending on the application's *char_type*. This is what I have so far:

// the very short version #define BOOST_LOG_STR(x) ( x, L ## x)

The problem I have is when using it this way:

BOOST_LOG_STR("this " " and that");

It gives me the eror - concatenating wide and narrow strings. How do I get 'round that? Thanks!

Hi John, This doesn't seem like a Boost or even a C++ libraries question... is there a more appropriate place for it? Regards, -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
