The compiler is right. Try something like this:

template <class T>
class AES
{
    private:
static const boost::array<T, 30> Rcon;

};

template <typename T>
const boost::array<T, 30> AES<T>::Rcon =
            {
                 0x01, 0x02, 0x04, 0x08,
     0x10, 0x20, 0x40, 0x80,
     0x1b, 0x36, 0x6c, 0xd8,
     0xab, 0x4d, 0x9a, 0x2f,
     0x5e, 0xbc, 0x63, 0xc6,
     0x97, 0x35, 0x6a, 0xd4,
     0xb3, 0x7d, 0xfa, 0xef,
     0xc5, 0x91
            };
