我刚开始在Windows上使用clang-cl3.7。我试图通过Visual 2015和低谷命令行在WIN8.1机器上编译我的代码。不用说，在此之前，在相同的cmd中，我使用vsvarsall选项运行amd64。

这是我的代码：

代码语言：javascript
复制
#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;
 }

下面是我在命令行中输入的内容：

代码语言：javascript
复制
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"

在VS2015中编译是正常的，但是我不能在命令行上编译，因为我得到了这个错误：

最后，我发现需要在命令行中添加以下内容：

代码语言：javascript
复制
-fms-compatibility-version=19.00

在对Clang bug报告#24231的答复中，Reid Klecker解释了为什么这是必要的：

“在Visual 2015中，char16_t变成了内置类型。以前，它不能是内置的，因为2013年在标头中定义了它。默认情况下，Clang试图与2013年兼容。要想达到2015年的目标，请将-fms-compatibility-version=19传递给clang-cl。这个参数可以是cl /?输出的全部版本号。”

所以我的最后命令是(包括普通的libs)：

代码语言：javascript
复制
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"
