Clang doesn't format the files and throw errors that it failed to find imports from external libraries (I use cmake)

#include "sherpa-onnx/c-api/c-api.h"
'sherpa-onnx/c-api/c-api.h' file not foundclang(pp_file_not_found)

the headers available in build/_deps/sherpa-src/include.

The project compiles successfuly with cmake. I also tried to produce compile_commands.json and place it in root folder. it didn't helped.

https://github.com/thewh1teagle/loud.cpp

Also clangd says there's too many errors and it doesn't do anything except for showing the error. no formatting etc.

Logs
Please attach the clangd log from the "Output" window if you can.
If possible, run with --log=verbose - note that the logs will include the contents of open files!

This bug actually belongs on clangd/clangd
Regardless, do you have the entry of the compile_commands.json for that file?

Also, could you attach logs taken with --log=verbose please?

With compile_commands.json it works well. but I have another project that I can't produce compile_commands.json. I need to specify the path. can't we specify additional includes path in settings.json?
I tried, but it didn't worked.

Not in settings.json, but clangd has a config file (.clangd in the project directory) where you can specify includes, for example:

CompileFlags:
  Add: [-I/some/include/path, -I/another/include/path]

Does it supports relative path so it will work for others that uses the project in vscode?

Sort of. You can use a relative path, but the path will be interpreted relative to the working directory in which the compile command runs, which is usually the directory containing the source file. So this tends not to be very useful unless the source files are all in one directory. (There is an open issue about this: clangd/clangd#1038.)

So for this kind of use case, a compile_commands.json file generated after the project is checked out (for example by running cmake) tends to work better.

I'll see if there's some way I still can use compile_commands.
So I understand that I need either specify absolute paths in .clangd or produce compile_commands.
It would be useful if we can use relative paths which are relative to project root

JVApen commented Nov 29, 2024

I've encountered a similar problem where I have some dynamic info into the config file. I've added a task that runs on opening the project directory. This takes a template and replaces some placeholders including the current directory.

I know it is not ideal, though it works as workaround.

Add this to your settings.json:

    "clangd.fallbackFlags": [
        "-I includepath"
    ]
