declaration does not declare anything - exception - Boost-users

3 Feb 2010

      Hi,

When I compile with Xcode I get a 'declaration does not declare 
anything' error on boost/exception/diagnostic_information.hpp.

However, the exception test run fine when I compile with bjam 
--toolset=darwin ...

I am quite sure both use the same compiler (g++-4.0.1) and have the same 
options (I copied from the bjam set to Xcode).

I now outcommented it (see below), but this is not a permanent solution. 
It should be valid, so what am I doing wrong regarding Xcode?

Any help would be very much appreciated!

Best, Dirk

template <class T>
        struct
        enable_boost_exception_overload
            {
            struct yes { char q[100]; };
            typedef char no;
            //static yes check(exception const *);
            //static no check(...);
            enum e { value=sizeof(/*check*/((T*)0))==sizeof(yes) };
            };

        template <class T>
        struct
        enable_std_exception_overload
            {
            struct yes { char q[100]; };
            typedef char no;
            //static yes check(std::exception const *);
            //static no check(...);
            enum e { value = !enable_boost_exception_overload<T>::value 
&& sizeof(/*check*/((T*)0))==sizeof(yes) };
            };

declaration does not declare anything - exception
