Compile error. Unable convert form nullptr to nullptr&&

[kirill-782]

I can not compile json.hpp.

error C2664: "BasicJsonType *nlohmann::detail::json_sax_dom_parser::handle_value(Value &&)": невозможно преобразовать аргумент 1 из "nullptr" в "nullptr &&"

problem code:

    bool null() override
    {
        handle_value(nullptr); 
        return true;
    }

What code do you try to compile? Which compiler are you using? What version of the library are you using?

[kirill-782]

visual studio 2015 (vc140). library downloaded from develop branch (last version)

#include <nlohmann/json.hpp> // single include

using namespace std;

using json = nlohmann::json;

int main( void )
{
	json j = "{ \"happy\": true, \"pi\": 3.141 }"_json;
	return 0;
}

Is that compiler supported? From the README: Microsoft Visual C++ 2015 / Build Tools 14.0.25123.0 (and possibly later)

[kirill-782]

Microsoft Visual Studio Enterprise 2015
Версия 14.0.25431.01 Update 3
Microsoft .NET Framework
Версия 4.7.03056

Could you try to remove using namespace std?

[kirill-782]

Nothing has changed

[nlohmann]

That is strange as we use MSVC 2015 with AppVeyor in your CI suite.

Can any macro be defined? Or any compilation option? Can you sln the file?

[nlohmann]

Maybe related: #987.

What do you mean by that?

@kirill-782 Could you comment on #1135 (comment) ?
