c++ / clangd - are these logs normal?

[sbromberger]

I have clangd 15.0.7 installed and have a very basic hello world program. Are these logs indicative of any sort of problem?

They look normal

[sbromberger]

Thanks! I was concerned because they were tagged as errors. Why is that?

clangd is printing those lines to stderr. We log stderr at the error level since other language servers tend to print error info (stacktraces etc.) on stderr
