буст матрица с реликвией

Я пытаюсь использовать буст матрицу fb_t, которая является реликвия объект, представляющий элемент конечного поля. Вот как fb_t определяется из документа:

typedef uint64_t dig_t
typedef align dig_t fb_t[FB_DIGS+PADDING(FB_BYTES)/(FB_DIGIT/8)]

и вот мой код:

#include <iostream>
#include <boost/numeric/ublas/matrix.hpp>

extern "C" {
#include <relic.h>
}
#include "relic_test.h"
using namespace std;
typedef boost::numeric::ublas::matrix<fb_t> matrix;

int main(void) {
core_init();
fb_param_set_any();
fb_param_print();

matrix mat(2,2);

core_clean();
return 0;
}

Я получил следующую ошибку:

Я не совсем уверен, о чем сообщение об ошибке. Любая идея?
