query regarding parallel algorithms and error message
I have installed boost to work with Windows Microsoft Visual C++ Cygwin g++ Linux openSuSe I can compile and run test programs On all three versions.

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. ᐧ On Sun, Jun 24, 2018 at 6:58 AM, ian D Chivers via Boost-users < boost-users@lists.boost.org> wrote:

I get similar messages when trying to use any of the serial Or parallel routines.
The documentation says that I only need to include

Any thoughts?

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