Clang在Windows 10

问题描述

我遵循official tutorial使用Microsoft VS 2019社区版本构建clang / LLVM，并且我遵循this post将clang作为C ++编译器嵌入到我的应用程序中。

我将Windows SDK和C ++头文件夹复制到名为 um 和 14.27.29110 的桌面上，我有名为test.cpp的示例C ++代码。当我尝试运行程序来编译test.cpp并生成可执行文件时，clang在不同的头文件中生成错误，如下所示：

clang -cc1 version 12.0.0 based upon LLVM 12.0.0git default target x86_64-pc-windows-msvc
#include "..." search starts here:
#include <...> search starts here:
 C:/Users/Zirian/Desktop/14.27.29110/include
 C:/Users/Zirian/Desktop/um
End of search list.

示例代码：

#include <iostream>

int main()
{
    std::cout << "this is a test" << std::endl;     
    while(1)
    {
        
    }
    return 0;
}

我的程序：

#define _CRT_SECURE_NO_WARNINGS    //disables the "getenv" error

#include "cc1_main.cpp"

int main()
{
    std::vector<const char*> argsX{"-v","-IC:/Users/Zirian/Desktop/14.27.29110/include","-IC:/Users/Zirian/Desktop/um","-std=c++11","-stdlib=libc++","-x","c++","test.cpp" };
        
    if (int res = cc1_main(argsX,"",nullptr))
        exit(-1);

    return 0;
}
