Unexpected Language Server Errors

Hi,
I am now getting drv_unknown_argument errors for my recent project builds -

Unexpected Problems:

What is this, can it be removed? Here is the example project which displays this (see test\ in this proj for detail) -

• esp32_proj #forum_debug(HEAD:F3BC)

Here is the config for that demo

Hello,

Looks like .clangd configuration file is missing in your project with the below settings. Could you please check?

Code: Select all

CompileFlags:
  CompilationDatabase: build
  Remove: [-m*, -f*]

Ok, imported your project and recompiled and I could reproduce the problem!

> set(EXTRA_COMPONENT_DIRS ${CMAKE_CURRENT_LIST_DIR}/../core)

Since you’ve configured core as an external component, clangd expects every external component to have its own .clangd file to avoid these errors. This is a limitation of clangd, and we hope it will eventually handle this recursively for all components added to the project.

For now, you can resolve the issue by adding a .clangd file inside your core component. For example, here’s the .clangd configuration I used in the core component, which resolved the errors:

Code: Select all

CompileFlags:
  Remove: [-m*, -f*]

I hope that helps!
