Hi Team,

Greetings for the day.

I am currently facing the problem with process extension as documented here http://www.boost.org/doc/libs/1_64_0/doc/html/boost_process/design.html#boos... . I am testing the boost 1.64 version macOS, and unable to use the below functionality.

void test() {

cout << "On Setup" << endl;

std::function on_st = test;

bp::child c2("ls", boost::process::extend::on_setup(on_st));

}

*Error: *

/usr/local/include/boost/process/detail/handler.hpp:33:9: No matching function for call to object of type 'std::__1::function'
