Clangd 与 MinGW 的问题

Question

我一直将 Neovim 与 clangd 用于 C，并且在处理包含

windows.h

的 C++ 文件时遇到配置问题。虽然我已经设置了配置文件

config.yaml

以使用 MinGW 编译器，对于 C 文件没有任何问题，但在处理 C++ 文件时，clangd 似乎找不到

windows.h

。

这些是我的旧

config.yaml

（与c配合良好）：

CompileFlags:
  Compiler: x86_64-w64-mingw32-gcc
  Add: ["-I../headers", "-I$INCLUDE_PATH"]

但现在我想使用 c++，所以 这是我的新

config.yaml

：

If:
  PathMatch: .*\.c .*\.h

CompileFlags:
  Compiler: x86_64-w64-mingw32-gcc
  Add: ["-I../headers", "-I$INCLUDE_PATH"]
---

If:
  PathMatch: .*\.cpp .*\.hpp

CompileFlags:
  Compiler: x86_64-w64-mingw32-g++
  Add: ["-I../headers", "-I$INCLUDE_PATH"]
---

这些事情发生了：

即使它编译没有任何问题。

这些是 neovim LSP 日志（如果有帮助的话）。

这个问题与我的新配置有关吗？如果是这样，我如何配置 clangd 以使用 Mingw 编译器来处理 C 和 C++？

谢谢！

我尝试过调整路径和配置，但到目前为止还没有任何运气。任何有关如何解决此问题的建议将不胜感激。

Answer 1

经过几次尝试，我发现问题出在 clangd 没有识别

x86_64-w64-mingw32-g++

的包含目录。

我不太明白为什么它适用于

x86_64-w64-mingw32-gcc

而不是

x86_64-w64-mingw32-g++

。

但是，为了解决这个问题，我使用以下命令找到了 g++ 的所有包含目录：

x86_64-w64-mingw32-g++ -print-search-dirs

这就是输出：

install: /usr/lib/gcc/x86_64-w64-mingw32/12-win32/
programs: =/usr/lib/gcc/x86_64-w64-mingw32/12-win32/:/usr/lib/gcc/x86_64-w64-mingw32/12-win32/:/usr/lib/gcc/x86_64-w64-mingw32/:/usr/lib/gcc/x86_64-w64-mingw32/12
-win32/:/usr/lib/gcc/x86_64-w64-mingw32/:/usr/lib/gcc/x86_64-w64-mingw32/12-win32/../../../../x86_64-w64-mingw32/bin/x86_64-w64-mingw32/12-win32/:/usr/lib/gcc/x86
_64-w64-mingw32/12-win32/../../../../x86_64-w64-mingw32/bin/
libraries: =/usr/lib/gcc/x86_64-w64-mingw32/12-win32/:/usr/lib/gcc/x86_64-w64-mingw32/12-win32/../../../../x86_64-w64-mingw32/lib/x86_64-w64-mingw32/12-win32/:/us
r/lib/gcc/x86_64-w64-mingw32/12-win32/../../../../x86_64-w64-mingw32/lib/

从这些目录中，我选择了这三个：

• /usr/lib/gcc/x86_64-w64-mingw32/12-win32/include/c++

  ：该目录包含 C++ 标准库的主要头文件。它包括容器（如向量、映射等）、算法、迭代器和其他标准 C++ 组件的标头。

• /usr/lib/gcc/x86_64-w64-mingw32/12-win32/include/c++/x86_64-w64-mingw32

  ：该子目录包含 C++ 标准库的特定于体系结构的标头。它可能包括优化或特定于 MinGW-w64 使用的 x86_64 架构的标头。

• /usr/lib/gcc/x86_64-w64-mingw32/12-win32/include/c++/backward

  ：此子目录包含旧版本 C++ 标准库的兼容性标头。它可能包含与旧代码库保持兼容性或提供已弃用功能的标头。

所以我确实将

.config/clangd/config.yaml

更改为：

If:
  PathMatch: .*\.c
CompileFlags:
  Compiler: x86_64-w64-mingw32-gcc
  Add: ["-I../headers", "-I$INCLUDE_PATH"] # These two arguments are not affecting anything; they just match my needs.
---
If:
  PathMatch: .*\.cpp
CompileFlags:
  Compiler: x86_64-w64-mingw32-g++
  Add: ["-I../headers", "-I$INCLUDE_PATH", "-I/usr/lib/gcc/x86_64-w64-mingw32/12-win32/include/c++", "-I/usr/lib/gcc/x86_64-w64-mingw32/12-win32/include/c++/x86_64-w64-mingw32", "-I/usr/lib/gcc/x86_64-w64-mingw32/12-win32/include/c++/backward"]
---

小提示：在问题帖子中，我没有使用命名空间 std。
