Windows上的clang和<iostream>

Question

根据http://clang.llvm.org/get_started.html 我使用Visual Studio 2010在Windows上完成了ALL_BUILD,并使用$ PATH = ... ClangSourcBuildPath ...\build\bin \将构建的内容添加到我的系统路径中发布

我现在可以在控制台上编译以下文件:

$> clang file_c.c

//file_c.c
#include <stdio.h>

int main() 
{
  printf("hello world\n");
  return 0;
}

但如果我对以下文件执行相同的操作($> clang file_cpp.cpp):

//file_cpp.cpp
#include <iostream>

int main()
{
    std::cout << "Hello World!";
    return 0;
}

我收到以下错误:

在file_cpp.cpp中包含的文件中:1:

In file included from C:\Program Files (x86)\Microsoft Visual Studio\VC98\include\iostream:9:

...

我也尝试过:

$> clang ++ file_cpp.cpp
$> clang -x c ++ file_cpp.cpp

但我仍然得到同样的错误.

有人能解释我有什么不对吗？

-fms-extensions让 clang 解析 VC++ 标头需要某些标志（我认为是，不太确定确切的选项）。

您将遇到的下一个问题是无法链接生成的可执行文件。这是因为 clang 使用与 MSVC 不同的名称修饰，并且会导致未定义的引用。

如果你想在 Windows 上使用 Clang（目前可以使用 MinGW-w64），你可以使用我的预构建包，你需要

1. 铿锵3.2

2. 海湾合作委员会4.6

解压到同一目录。在这种情况下，GCC 仅用于调用链接器。Clang 可以用来编译一切。

目前无法将 clang 用于 C++ 和 Visual Studio headers+libs。C 应该可以工作，但我还没有测试过，并且可能存在其他 ABI 问题阻止其工作。
