I have a simple example:
[cpp]
#include <boost/coroutine2/coroutine.hpp>
using YieldType = boost::coroutines2::coroutine<int>::pull_type;
class Test {
public:
Test()
: m_coro(std::bind(&Test::callMe, this, std::placeholders::_1))
{}
void callMe(YieldType &yield) {}
using Call = boost::coroutines2::coroutine<int>::push_type;
Call m_coro;
};
int main()
{
Test t;
return 0;
}
[/cpp]
$ g++ test.cpp -std=gnu++14 -lboost_coroutine -lboost_context
works just fine
$ g++ test.cpp -std=gnu++17 -lboost_coroutine -lboost_context
gives me following errors:
