VSCode SonarLint detecting errors

Postby zazas321 » Tue Dec 19, 2023 12:29 pm

I an running a simple sample project on VSCode (esp-idf v5.0.3)

We are using SonarLint extension for VSCode to give us some guidelines for writing a decent code. I have noticed that even with the
most basic sample, I am getting 10 Problems:

I have ensured that the SonarLint is pointing to the right compile_commands json:

Does anyone else use SonarLint and know what could be the problems? Can you recommend a way to solve them or recommend another linter?

You can check this for the #include error : https://stackabuse.com/bytes/troublesho ... n-vs-code/

I have tried to restart vscode as shown in the link that you have provided.

Additionally, I have tried the following:

But clicking on the lightbulb does not do anything except open the IntelliSense Configuration window:

Perhaps I should add a Compiler path in .vscode/c_cpp_properties.json as shown below:

What would be the compiler path for esp-idf projects?

Not sure. I just hope somebody from the esp authority will look into this thread.
