I suppose I need to #define MaxNumber for PP? ---------------------------------------------------------------------------- -- #include <iostream> #include <iterator> #include #define N 16 int main() {   const int elts[] = { BOOST_PP_ENUM_PARAMS(N, BOOST_PP_EMPTY()) };   std::copy(elts, elts + N, std::ostream_iterator<int>(std::cout, "\n")); }  Roman Perepelitsa. ---------------------------------------------------------------------------- -- 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.
