如何在Windows上使用clang和mingw-w64头文件

23

我从http://llvm.org/releases/3.9.0/LLVM-3.9.0-win32.exe安装了clang 3.9。

clang version 3.9.0 (branches/release_39)
Target: i686-pc-windows-msvc
Thread model: posix
InstalledDir: C:\Program Files\LLVM\bin

使用gcc 6.2.0 (Mingw-w64)

gcc (i686-posix-dwarf-rev1, Built by MinGW-W64 project) 6.2.0

我电脑上没有安装MSVC和Windows SDK，我需要clang的某些特定功能，并希望将其替换为g++，因为我使用C++。当我尝试编译简单文件时，出现以下错误：

fatal error: 'string' file not found

这是否意味着我的当前clang安装不支持在Windows上使用mingw？基本上，我想做的就是使用来自我的mingw-w64安装的头文件和库。我正在寻找解决方案，但并没有找到任何有用的信息。我不知道该怎么办。

这是否也意味着我的clang安装依赖于我没有的MSVC？

这不再适用于最新的二进制文件（3.7.1、3.8、3.9）了，因为这些文件是使用Visual Studio和为Visual Studio编译的。

您可以安装完整的Visual Studio 2015（大约需要8GB），或者安装“Microsoft Visual C++ Build Tools 2015 Update 3”，其中包含VS的命令行工具和Clang需要的标准C++头文件。

我觉得这解释了一切。这是否意味着我需要使用mingw构建才能使其与mingw配合使用？

安装旧版本的MinGW，即3.7.0 RC3，它能够工作。

你可以注意到版本差异在于i686-pc-windows-gnu vs i686-pc-windows-msvc。

我认为如果他们没有在源代码中弄坏什么东西并且您自己构建了它，那么clang 3.9也可以工作。但是最好能够让最新的3.9与MinGW一起工作。我懒得尝试自己构建它。

编辑: 也有一些适用于MinGW的软件包https://github.com/Alexpux/MINGW-packages，您可以使用MSYS2进行安装，这些软件包似乎提供了对clang的支持。有一些与3.8和3.9相关的提交。

希望这将有助于遇到类似问题的人。

正确的做法是这样的...

clang -target i686-pc-windows-gnu test.c -otest.exe

或者，如果您想要64位输出...

clang -target x86_64-pc-windows-gnu test.c -otest.exe

Clang会根据您的路径确定头文件和库的位置。确保您的路径中只有您正在定位的Mingw版本。

默认情况下，当前版本的Clang（目前为5.0.0）将针对x86_64-pc-windows-msvc进行目标设置。

例如...

Microsoft Windows [Version 10.0.16299.19]

C:\Users\burito>copy con hello.c
#include <stdio.h>

int main(int argc, char *argv[])
{
    printf("Hello World!\n");
    return 0;
}
^Z
