Hey thanks, i define th vecotr in the .h:

 //bit vector to store the errror corrected link control word
   bit_vector decoded_lcw_vec;

i fill th vector like this:

bit_vector decoded_lcw_vec(corrected_array, corrected_array + sizeof
corrected_array / sizeof corrected_array[0]) ;

and I can see the right values are there using cout.  i have a function
to return the vector:

const_bit_vector&
ldu1::get_vec() const
{
  return decoded_lcw_vec;
}

and then I use the that funtion as the arguement in extract:

uint16_t
ldu1::lcf() const
{
   const size_t LCF_BITS[] = {
    0, 1, 2, 3, 4, 5, 6 , 7
   };
   const size_t LCF_BITS_SZ = sizeof(LCF_BITS) / sizeof(LCF_BITS[0]);
   const uint16_t lcf = extract(get_vec(), LCF_BITS, LCF_BITS_SZ);
   return lcf;

}

Thanks!
