Re: [boost] SUN Compiler option -features=tmplrefstatic

Hi,

Thanks for that answer, but I still don't think I understand. This sample
test code builds with and without the -features=tmplrefstatic argument, so I
guess I need a code example to clarify it, if you don't mind.

Thank you,
-Sid Sacek

template< typename Ty > struct XYZ
{
        static int si;
        static void foo( void );
        XYZ( void ) {  si = 555;  foo();  }
};

int XYZ< int >::si = 333;
template<> void XYZ< int >::foo( void ) {  return;  }

int main( void )
{
        XYZ< int > xyz;
}

The short answer is very simple. By default Sun C++ compiler does not
allow to refer static symbols from templates. -features=tmplrefstatic
turns on this ability.
