      Thanks for the reply. I now get

I presume that if I replace the or with something belonging to an earlier standard that this may get me a bit further.

Any thoughts?

Change parallel_stable_sort to boost::sort::parallel_stable_sort.  The public api is entirely in the boost::sort namespace, the documentation just omits it for brevity.

I get similar messages when trying to use any of the serial

The documentation says that I only need to include

#include 

To make things available.

Any thoughts?
