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.
However I get the following error messages when trying To call one of the
routines in
https://www.boost.org/doc/libs/1_67_0/libs/sort/doc/html/sort/parallel.html
Here is the cygwin message
$ g++ ch3604.cxx
ch3604.cxx: In function 'int main()':
ch3604.cxx:155:3: error: 'parallel_stable_sort' was not declared in this
scope
parallel_stable_sort( x.begin() , x.end() );
Here is the Microsoft message

ch3604.cxx
I get a similar message on openSuSe linux.
Here is the top part of the source file
#####
#include <iostream>
#include <algorithm>
#include <array>
#include <chrono>
#include <random>
#include <string>
#include
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
#include
To make things available.
Any thoughts?

Thanks for the reply. I now get

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

I presume that if I replace the or with something belonging to an earlier standard that this may get me a bit further.
`or` was a keyword in C++98 (See [lex.digraph]). Try compiling with /permissive- In Christ, Steven Watanabe
Thanks to Steven Watanabe /permissive- Fixed the Microsoft problem. Now compiles and runs.
