The following simple example fails to compile with VC71, (OK with Intel 8.1). Is there a workaround for this? Regards, Richard. ---------------------- #include <boost/lambda/bind.hpp> struct S{ void mfn1(){}; void mfn2() throw() {}; }; int main() { using namespace boost::lambda; S s; bind(&S::mfn1,_1)(s); // OK bind(&S::mfn2,_1)(s); // Error with VC71 } ---------------------- cl /c /Od /Gm /EHsc /RTC1 /MLd /Zc:wchar_t /Zc:forScope /GR /ZI /W3 /D "WIN32" /D "_DEBUG" /D "_CONSOLE" /D "_MBCS" /Fo"Debug/"
