Thanks very much.
How about generating
const int elts[] = { other_array[0], .... other_array[N-1] };

Basically I wished to initialize at compile time 1 const array based on
another,
I don't see any metaprogramming that allows this.

#include <iostream>

#include <iterator>

#include <boost/preprocessor.hpp>

#define N 10

int main() {

const int other_array[N] = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 };

const int elts[] = {

#define BOOST_PP_LOCAL_MACRO(I) BOOST_PP_COMMA_IF(I) other_array[I]

#define BOOST_PP_LOCAL_LIMITS (0, N)

#include BOOST_PP_LOCAL_ITERATE()

};

std::copy(elts, elts + N, std::ostream_iterator<int>(std::cout, "\n"));

}
