compile_commands.json generation?

[GoldsteinE]

Hi! I was wondering if there any way to use cxx with clangd?

This would be a question for the cc crate. Cxx-build is ordinary and simple as far as use of the cc crate.

For other people who come here by search, bear -- cargo build will generate the compile_commands.json, but you need something to trigger the build script of cxx (e.g. changing some cpp file, or using cargo clean) before it.

But it is still very manual. The cc related issue is rust-lang/cc-rs#497
