Windows 8.1上的clang cl编译错误
clang-cl on Windows 8.1 compiling error
我刚开始在Windows上使用clang cl 3.7。我试图通过Visual studio 2015和命令行在我的WIN8.1机器上编译我的代码。不用说，在此之前，在同一个cmd中，我使用amd64选项运行了vsvarsall。
这是我的代码：
#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;
}
以下是我在命令行中输入的内容：
C:Program FilesLLVMbin>"C:Program FilesLLVMbinclang-cl.exe" "C:UsersDav
idSourceReposDY Obfuscator 2015-20162DY ObfuscatorSource.cpp"
在VS2015中编译工作正常，但我无法在命令行上编译，因为我收到了以下错误：
C:Program FilesLLVMbin>"C:Program FilesLLVMbinclang-cl.exe" C:testSourc
e.cpp

我终于发现我需要在命令行中添加以下内容：
-fms-compatibility-version=19.00
Reid Klecker在回复Clang错误报告#24231时解释了为什么这是必要的：
"在〔Visual Studio〕2015中，
char16_t成为内置类型。以前，它不能内置，因为2013在它们的标头中定义了它。默认情况下，Clang尝试与2013兼容。要实现2015年目标，请将[-fms-compatibility-version=19]传递给clang-cl。参数可以是cl /?吐出的整个版本号。"
所以我的最后命令是（包括一般的libs）：
clang-cl.exe "C:testSource.cpp" -fms-compatibility-version=19.00 ^
-Fe"C:testSource.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"
