Compilation errors with MSVC 2019 with c++17 option enabled #468

Open vtabota opened 4 years ago

vtabota commented 4 years ago

Expected Behavior

Expected to compile with c++17 enabled

Actual Behavior

Requires c++14 set

Steps to Reproduce the Problem

New C++ console project Project properties, C/C++, Language, Advanced, Set ISO C++ 17

Source file

#include <boost/di.hpp>
#include <cassert>
#include <memory>

namespace di = boost::di;
struct interface {
    virtual ~interface() noexcept = default;
    virtual int get() const = 0;
};

class implementation : public interface {
public:
    int get() const override { return 42; }
};

struct example {
    example(std::shared_ptr<interface> i) {
        assert(42 == i->get());
    }
};

int main() {
    const auto injector = di::make_injector(
        di::bind<interface>.to<implementation>()
    );

    injector.create<std::unique_ptr<example>>();
}
