Are you sure that you're not missing a #include?
It works for me.

#include <boost/sort/sort.hpp>
#include <vector>

int main() {
  std::vector<int> x = { 3, 1, 4 };
  boost::sort::parallel_stable_sort( x.begin() , x.end() );
}

`or` was a keyword in C++98 (See [lex.digraph]).  Try
compiling with /permissive-
