clang/clang++ 在 Windows 中找不到 C/C++ 头文件？

Question

1 小时前我从http://llvm.org/pre-releases/3.6.0/ 下载了 llvm-3.6.0-rc4-win32.exe。

我尝试编译只打印“hello”的简单 C 代码，但没有编译，因为 clang.exe 找不到 stdio.h。 当我使用具有相同代码的 clang-cl.exe 时，它​​起作用了。

即使使用 iostream ，我也对 clang++ 有同样的问题，我将 -I 标志添加到 GCC (4.9.1) C++ headers ，结果：

C:\Users\One\Desktop>clang++ -I c:\MinGW\x86_64-w64-mingw32\include\c++ main.cpp -lib=libstdc++

In file included from main.cpp:1:
c:\MinGW\x86_64-w64-mingw32\include\c++\iostream:38:10: fatal error:'bits/c++config.h' file not found

#include <bits/c++config.h>
1 error generated.

有人知道如何解决这个问题吗？

编辑： 我在 MinGW 文件夹中找到了 bits/c++config.h 我将它添加到 -I 标志和其他 .

我导致链接错误：

为什么会这样？我应该总是做这一切来让 clang 工作吗？

Answer 1

试试这个

Installing Clang 3.5 for Windows.

问候。

Answer 2

目前的做法是……

• 安装mingw-w64-install.exe（当前为7.2.0，请务必在询问时将“i686”设置为“x86_64”）
• 安装Clang for Windows (64-bit)（目前为5.​​0.0）

询问时，默认路径。将它们都放在您的系统路径中（所有用户都可以访问）。如果您要求，Clang 安装程序会将 clang 放入路径中，对于 Mingw，您必须手动执行，我推荐 PathEditor2。对于当前版本的 Mingw，要添加到路径的目录是 C:\Program Files\mingw-w64\x86_64-7.2.0-posix-seh-rt_v5-rev0\mingw64\bin

然后在调用 Clang 时，使用...

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

Clang 将搜索您的路径以查找 Mingw 标头和库，确保您的路径中只有一个版本。

Answer 3

我们尝试按照 llvm.org/docs/GettingStartedVS.html 中的说明运行 Clang 测试。该过程因类似原因而失败，表明未找到 stdio.h。尝试在另一台机器上安装它是成功的。我们运行了一些详细的运行来识别机器之间的差异，使用“-v”标志来详细描述链接过程。

我们发现工作安装在路径变量中具有 Windows System32 目录 (C:\Windows\System32) 的默认映射。故障机器没有映射该路径。我们添加了故障机器的路径，一切正常。

这可能是系统管理员出于安全原因实施的更改。如果不允许添加路径，请将“-isystem C:\file\location\here”添加到您希望包含的每个文件的 clang 命令中。
