Re: [Boost-users] Fwd: bind, template member function and thread

I used this piece of code :

#include <boost/shared_ptr.hpp>
#include <boost/bind.hpp>

namespace
{
    template< typename T > class A {};

    class B {};

    enum E
    {
        eVal
    };

    class C
    {
    public:
        template< typename T > void F( boost::shared_ptr< T >,
boost::shared_ptr< A< unsigned char > >, E = eVal ) {}
    };
}

int main()
{
    boost::shared_ptr< A< unsigned char > > a( new A< unsigned char > );
    boost::shared_ptr< B > b( new B );
    boost::shared_ptr< C > c( new C );
    boost::bind( &C::F< B >, c, b, a, eVal );
    return 0;
}

Does not compile under VC2003, but compiles fine under VC2005. So, id
someone already used boost.bind under VC2003 ? I really would appreciate
help ...

Le temps des cerises reviendra. Dans l'immédiat, c'est le temps des noyaux.
Courage.
