Unable to make clangd work

[CarterLi]

I have generated compile_commands.json and placed it at the project root ( see the file explorer )

The same setup works in helix.

Did you start the LSP? (Either via lsp menu, or command palette)

[CarterLi]

Didn't know that it must be started manually. Shouldn't it be started automatically?

[CarterLi]

The completion won't show up automatically when I type -> or .; the keyboard shortcut ctrl+space doesn't work either. If I manually show it, duplicated entries are displayed.

• Created an issue for the duplicate completions: LSP completion includes duplicate entries #1514
• The -> or . completion: disabled by default, you can enable it in the config:

• The ctrl+space should work, could it be you tried before LSP was ready?
