What compiler are you using?

I use VC7.1 and VC8.0 among others. Looks like you are experiencing a preprocessor problem, but I'm not sure. Try Boost static assert instead. Regards, -- Joel de Guzman http://www.boost-consulting.com http://spirit.sf.net

The error are now:

Oh. Definitely looks like a PP problem. Unfortunately I can't help you. I can't recreate the problem here. Regards, -- Joel de Guzman http://www.boost-consulting.com http://spirit.sf.net

When adding ::value to is_same<...> it works. Thanks Shunsuke for the tip. #include using namespace std; using namespace boost; int _tmain(int argc, _TCHAR* argv[]) { typedef fusion::map< fusion::pair, fusion::pair, fusion::pair > mymap; BOOST_STATIC_ASSERT((boost::is_same< fusion::result_of::at_key::type, char&>::value)); return 0; } I have downloaded the CVS Head but here I'm getting an Internal Compiler Error. Is that a known issue? Christian On 3/20/07, shunsuke wrote:

'::value' seems missing. Well, IIRC, Boost1.34 MPL_ASSERT has a problem around __LINE__ under IDE. That was fixed with CVS Head. But I'm not sure.
