clang“hello，world！”链接错误 [英] clang "hello, world!" link errors in windows

问题描述

我刚刚下载了CLang源代码，使用CMake创建了一个Visual C ++ 10 IDE工作区，并从Visual C ++ 10.0（express）创建了所有的东西。

I just downloaded the CLang sources, made a Visual C++ 10 IDE workspace by using CMake, and built everything from Visual C++ 10.0 (express).

hello world上的一系列链接器错误：

Now I get a bunch of linker errors on hello world:

d:\dev\test> type con >foo.cpp
#include <iostream>
using namespace std;
int main() { cout << "Hello, cling-clong world!" << endl; }
^Z

d:\dev\test> clang++ foo.cpp
foo-839435.o : error LNK2019: unresolved external symbol __ZSt4cout referenced in function _main

foo-839435.o : error LNK2019: unresolved external symbol __ZSt17iostream_categoryv referenced in function __ZSt15make_er

那么我能做些什么呢？

推荐答案

如果你想在Windows上试验Clang，我建议使用MinGW内置版本，像我在这里提供的（或自己使用你喜欢的MinGW工具链构建它）：

If you want to experiment with Clang on Windows, I suggest using a MinGW built version, like the one I provide here (or build it yourself using your favourite MinGW toolchain):

• 32位

64位

您将需要 gcc 和 clang 包（那些没有linux / mac / cygwin后缀），并提取它们到同一目录。 Clang使用gcc链接，并可以链接到GCC的libstdc ++，几乎允许访问C ++标准库。异常适用于32位版本。我没有运气调试信息，虽然。

You will need both the gcc and clang packages (those without linux/mac/cygwin suffixes) and extract them to the same directory. Clang uses gcc to link, and can link to GCC's libstdc++, pretty much giving you access to the C++ standard library. Exceptions work for the 32-bit version. I haven't had any luck with debug info though.

工作正在做出更好的MS支持Clang，但它是一个缓慢进行的任务。

Work is being done to bring better MS support to Clang, but it's a slowly progressing task.
