Clangd does not find standard headers/functions or other includes, even though program builds correctly.

[ymich9963]

Hi! I tried doing what's on the website (i.e. Installing, a Config file , Troubleshooting, ) but it didn't really get me anywhere. Basically clangd isn't recognising any external header files or function definitions. Meaning std libraries or other. My compile_commands.json gets generated by CMake and it only recognises the files in the project directory but the functions defined in them are still not recognised. Furthermore, I'm not sure how to use a .clang file to point to the correct paths.

As detailed below my setup uses MSYS2 and the project compiles just fine. I'm guessing clangd needs some more help (as do I) to parse my code and provide me with hints, autocomplete etc. I am aware that the website tries to provide ways to troubleshoot this, but searching everywhere has provided with no solution and I hope someone can assist because it appears other people have similar problems!

Logs

I can't figure out how to use verbose logging so apologies about that, Maybe someone can help me if it's required later on. Each error message in the log using :LspLog starts with this line, so I'm isolating it to make the logs more readable and concise:

[ERROR][2024-07-08 21:34:50] .../vim/lsp/rpc.lua:734 "rpc" "C:\\Users\\USER\\AppData\\Local\\nvim-data\\mason\\bin\\clangd.CMD" "stderr"

then by appending that line to the start of the log below you get the full log,

Here's some more information on how clangd is used in my configuration. This type of configuration with mason.nvim is very common so I don't think I'm doing anything crazy. Using :LspInfo in the currently open file, I get this output from mason.nvim,

The path points to a .cmd file with the following script which contains the clangd.exe.

@ECHO off
GOTO start
:find_dp0
SET dp0=%~dp0
EXIT /b
:start
SETLOCAL
CALL :find_dp0

endLocal & goto #_undefined_# 2>NUL || title %COMSPEC% & "C:\Users\USER\AppData\Local\nvim-data\mason\packages\clangd\clangd_18.1.3/bin/clangd.exe" %*

System information

Output of clangd --version: Doesn't work on terminal but I'm using the LSP Logs

Editor/LSP plugin: NeoVim and this is my LSP Lua file

Operating system: Windows 11

Please have a look at https://clangd.llvm.org/troubleshooting#cant-find-standard-library-headers-map-stdioh-etc, in particular the second half regarding --query-driver, that tends to be needed on Windows setups using MinGW or MSYS.

[HighCommander4]

Note, --query-driver is added in the same place as --log=verbose, so you'll need to figure out where that is.

I'm not a neovim user, but hopefully the pointers in this issue thread are helpful: https://github.com/llvm/clangd-www/issues/94

Of course! Thank you for your quick reply! Do I pass that in the compile_commands.json? Where do I write that? And by /path/to/mygcc does that mean the path to the standard header files or the C:\msys64\usr\bin path for GCC?

[HighCommander4]

Of course! Thank you for your quick reply! Do I pass that in the compile_commands.json? Where do I write that?

(See previous comment. Clangd arguments go in an editor-specific place, seems to be some kind of .lua file for neovim.)

And by /path/to/mygcc does that mean the path to the standard header files or the C:\msys64\usr\bin path for GCC?

It's the path to whatever compiler you're compiling with. In your case it's actually clang rather than gcc, so it would be something like C:\msys64\usr\bin\clang.

Thanks again for your help. I managed to figure it out thankfully. I'm not very knowledgable in lua!

Here's the log before the --query-driver=C:\msys64\usr\bin\clang.exe path added, with verbose logging. I have again removed the common clutter. I have an arrow to the cc1 command which shows that indeed it doesn't look where it should for the correct headers.

Any other input? Thank you again! I really appreciate it and I hope I can finally start a project using clangd. I've been debugging it on my own for a while.

EDIT: By the way the SNDFILE stuff is an external library, do I have to also add that path somewhere? It doesn't seem to find it but the project does build. Maybe I need to add some PATHs?

[HighCommander4]

Ah, my bad, I think I confused MinGW and MSYS in my mind. --query-driver solves this issue for MinGW users.

MSYS is a bit more special, I think what has worked in that case is to use the clangd from the package prepared by MSYS at https://packages.msys2.org/package/mingw-w64-x86_64-clang-tools-extra.

[HighCommander4]

To expand on that a bit, the relevant line of the log is this:

I[23:49:50.224] System includes extractor: successfully executed C:\\msys64\\usr\\bin\\clang.exe
    got includes: "/usr/local/include, /usr/lib/clang/11.0.0/include, /usr/include/w32api, /usr/include"
    got target: "x86_64-pc-windows-msys"\r\n

You can see that the include paths found by --query-driver have the format /usr/local/include, these are basically paths "inside" the emulation layer of MSYS. A "regular" clangd executable does not know how to locate these paths, only a clangd executable packaged as part of MSYS does.

[ymich9963]

Wow!!!! This is amazing!!! You were right I had to download the MSYS2 clang tools extra package, instead of using the one directly downloaded by mason.nvim!!! The --query-driver isn't needed, I just had to edit the file in C:\Users\USER\AppData\Local\nvim-data\mason\bin\clangd.cmd to point to the MSYS2 package clangd like so,

@ECHO off
GOTO start
:find_dp0
SET dp0=%~dp0
EXIT /b
:start
SETLOCAL
CALL :find_dp0

endLocal & goto #_undefined_# 2>NUL || title %COMSPEC% & "C:/msys64/clang64/bin/clangd.exe" %*

I'm using the /clang64 environment, but it should work under any environment you can get CLang from. Make sure the correct environment is in the PATH as well! (This is to anyone having this problem)

Last thing! Clangd doesn't seem to recognise the header files in the project tree. Right now it looks like this,

C:.
|   CMakeLists.txt
|   main.c
|
+---inc
|       header.h
|
\---src
        CMakeLists.txt
        other1.c

and this is my compile_commands.json,

[
{
  "directory": "/c/Users/USER/proj/sndfile-test/build",
  "command": "/clang64/bin/clang.exe  -I/c/Users/USER/proj/sndfile-test/inc -isystem /clang64/include  -o CMakeFiles/test.dir/main.c.o -c /c/Users/USER/proj/sndfile-test/main.c",
  "file": "/c/Users/USER/proj/sndfile-test/main.c",
  "output": "CMakeFiles/test.dir/main.c.o"
},

  "file": "/c/Users/USER/proj/sndfile-test/src/other1.c",
  "output": "src/CMakeFiles/src.dir/other1.c.o"
}
]

It says "header.h not found". Any ideas as to why clangd can't locate the header file under /inc?

[HighCommander4]

Any ideas as to why clangd can't locate the header file under /inc?

Nothing obvious jumps out, can you post a set of updated logs?

These lines from the log:

I[22:37:07.137] ASTWorker building file C:/Users/USER/proj/sndfile-test/main.c version 0 with command clangd fallback [C:/Users/USER/proj/sndfile-test] C:/msys64/clang64/bin/clang -resource-dir=C:/msys64/clang64/lib/clang/18 -- C:/Users/USER/proj/sndfile-test/main.c\r\n"

suggest that clangd is not using the compile_commands.json file for some reason.

[HighCommander4]

I suspect the reason may be related to the discrepancy between the format of the paths that the editor is sending to clangd (e.g. C:/Users/USER/proj/sndfile-test/main.c), and the format of the paths present in compile_commands.json (e.g. /c/Users/USER/proj/sndfile-test/main.c).

[HighCommander4]

Can you try changing the paths in the "file" and "directory" fields of compile_commands.json to use C:/ instead of /c/, and see if that makes any difference?

[ymich9963]

Doesn't line 12 in the logs signify it's loaded? Here's the new logs and new compile_commands.json file. Something broke...

Even just changing the two fields you mentioned breaks it

[HighCommander4]

Doesn't line 12 in the logs signify it's loaded?

Yeah, it looks like it's loaded, but (before the changes) clangd didn't consider its entries to be a match for the file being edited, due to the paths using different syntax.

Here's the new logs and new compile_commands.json file. Something broke...

Well, the error about header.h is gone :)

But the errors about the standard library includes are back :(

I'm kind of guessing at the cause here, but can you also try replacing /clang64/bin/clang.exe in "command" with C:/msys64/clang64/bin/clang?

[ymich9963]

It seems to be working?!?! Please check the logs and the compile commands below,

If it is working, do you know if there's a way to output the correct paths without manually doing anything? I'm not sure how this makes sense because I'm using the MSYS2 clang and clang tools, so shouldn't it know how to use the paths?

[HighCommander4]

It seems to be working?!?!

Great :)

do you know if there's a way to output the correct paths without manually doing anything? I'm not sure how this makes sense because I'm using the MSYS2 clang and clang tools, so shouldn't it know how to use the paths?

The only idea that comes to mind currently is maybe to use neovim from MSYS as well: https://packages.msys2.org/base/mingw-w64-neovim

[ymich9963]

Damn that's annoying. Any chance I could maybe use the Windows version of CMake to generate the paths? Or maybe that wouldn't work with MSYS2...

[HighCommander4]

I'm afraid I don't have a better answer than "try it and see" :/ I'm not a Windows user myself (nor a CMake user).

[ymich9963]

Alright! You've been more than helpful. I can't thank you enough!! I hope this issue also helps other people in a similar situation. Have a good day!

[ymich9963]

Just to 100% finish this issue. To fix the includes you can put in the full relative path to the file. In my case for example I used #include "inc/header.h" in main.c and the error went away without editing compile_commands.json.

[bon-ami]

I've got a similar failure, not sure whether to continue here or post a new issue. clang --target=x86_64-w64-mingw32 test.c OK using clangd as LSP in neovim (with ale as the plugin) fails. Thanks in advance. #include <stdio.h> generates 'stdio.h' file not found %USER%\AppData\Local\clangd\config.yaml

CompileFlags:
  Add: --target=x86_64-w64-mingw64

complile_flags.txt under same dir as test.c

--target=x86_64-w64-mingw64

[HighCommander4]

@bon-ami Please start by reading https://clangd.llvm.org/troubleshooting.html#cant-find-standard-library-headers-map-stdioh-etc, and using --query-driver in particular (which is mentioned as being necessary for MinGW).

If you can't get it to work, please file a new issue and attach clangd logs.

[bon-ami]

it turns out to be clang-tidy, instead of clangd that reported the failure. the config.yaml works. since it seems clang-tidy does not support windows, I'm using clangd only now. Thanks any way.
