clang-cl on WIndows 8.1 странная ошибка компиляции

Я только начал использовать clang-cl 3.7 на окнах. Я попытался скомпилировать свой код на моей машине WIN8.1 через Visual studio 2015 и через командную строку. Излишне говорить, что до этого, в том же cmd, я побежал vsvarsall с опцией amd64.clang-cl on WIndows 8.1 странная ошибка компиляции

Вот мой код:

#define UNICODE 
#include <Windows.h> 
#include <iostream> 

int main() { 

int a = 0; 
if(0) 
__asm _emit 0xE8 
else 
a=3; 

if (IsDebuggerPresent()) 
MessageBox(
    NULL, 
    (LPCWSTR)L"Debugger detected!!", 
    (LPCWSTR)L"!!!!!", 
    MB_ICONWARNING | MB_CANCELTRYCONTINUE | MB_DEFBUTTON2 
    ); 
return 0; 
}

Вот что я положил в командной строке:

C:\Program Files\LLVM\bin>"C:\Program Files\LLVM\bin\clang-cl.exe"  "C:\Users\Dav 
id\Source\Repos\DY Obfuscator 2015-20162\DY Obfuscator\Source.cpp"

Компиляция в VS2015 работал нормально, но я не могу скомпилировать в командной строке, потому что я получаю эта ошибка:

'char16_t' и' char32_t' является добавлением C++ 11, вы скомпилировали с соответствующими флагами? – YSC

какие флаги? Я так не думаю ... – user2554080

my bad http://stackoverflow.com/questions/25992401/how-to-add-std-c11-flag-to-clang-cl (clang по умолчанию для C++ 11 on Windows). – YSC

Наконец-то я обнаружил, что мне нужно добавить в командную строку следующее:

-fms-compatibility-version=19.00

В ответ на Clang bug report #24231, Рид Klecker объяснил, почему это необходимо:

"In [Visual Studio] 2015, char16_t became a builtin type. Previously, it could not be builtin because 2013 defines it in their headers. By default, Clang tries to be compatible with 2013. To target 2015, pass [ -fms-compatibility-version=19 ] to clang-cl . The argument can be the whole version number that cl /? spits out."

Так моя последняя команда (включая общие LIBS):

clang-cl.exe "C:\test\Source.cpp" -fms-compatibility-version=19.00^
    -Fe"C:\test\Source.exe" "kernel32.lib" "user32.lib" "gdi32.lib" "winspool.lib"^
    "comdlg32.lib" "advapi32.lib" "shell32.lib" "ole32.lib" "oleaut32.lib" "uuid.lib"^
    "odbc32.lib" "odbccp32.lib"

Кажется, что после этого ответа они добавили средства автоматической установки '-fms-compatible-version' на основе ваших переменных среды (на самом деле, проверив номер версии cl.exe). Итак, убедитесь, что у вас есть cl .exe', видимый для clang, и эта опция будет установлена автоматически. – thelink2012

@ thelink2012 Предполагается, что это должно быть в Clang 4.0? Используя предварительно созданные двоичные файлы в Windows 10 с MSVC 2017 (cl.exe 19.10), параметр совместимости по умолчанию по умолчанию 18. –

@DavidBrown Я нашел это поведение на Clang 3.9.1, не уверен, что они изменили его на 4.0. – thelink2012
