C::B does not find the thread. In the compilation settings (project>>build options and settings>>compiler) prescribed the use of C++14 (thread s are allowed with C++11).
Code that looks like this:
using namespace std;
In what could be the problem? I understand that my question is likely silly, but we always with something to start with...
PS In VS 2017 somehow another problem... "No such constructor, so in the parameters there was only a void-function". (Using C++14 similarly ordered)
