Can't make a row reduction with rationals

[IvanRenison]

Hi, I'm trying to use reducedRowEchelonize with rationals with this code:

#include <bits/stdc++.h>
#include <linbox/matrix/dense-matrix.h>
#include <linbox/solutions/echelon.h>

typedef Givaro::QField<Givaro::Rational> Field;

int main() {
  Field F;

  LinBox::DenseMatrix<Field> A(F);
  A.resize(3, 3);

  A.refEntry(0, 0) = 1;
  A.refEntry(0, 1) = 1;
  A.refEntry(1, 1) = 1;

  reducedRowEchelonize(A);

  for (size_t i = 0; i < 3; i++) {
    for (size_t j = 0; j < 3; j++) {
      std::cout << A.getEntry(i, j) << " ";
    }
    std::cout << std::endl;
  }
}

But when I run it get this error:

 *** ERROR *** : reducedRowEchelonize<RingCategories::RationalTag, Method::Elimination> does not exists.
(at  in )
terminate called after throwing an instance of 'LinBox::LinBoxError'
fish: Job 1, './a.out' terminated by signal SIGABRT (Abort)

I'm also not able to do it with an integer matrix
