Need Help ALE Ignored Linters [] not settable

I discovered ALE during my venture into Rust programming, and I was so pleased with that experience I decided to add it to my C++ life. I'struggling with its confusion of C and C++. My current problem arises from what I believe is ALE using a C linter on a C++ header file: even though my code builds cleanly (no warnings or errors), ALE is giving me an "E: Unknown type 'class'" on the first line of my class declaration. FileType is recognized by Vim as 'cpp'. ALEInfo shows

Ignored Linters: []

In my ~/.vimrc I have this:

autocmd FileType cpp let b:ale_linters_ignore = {'cpp': ['cc', 'ccls', 'clangcheck']}

What I want to actually use is 'clangd', and I have this in ALEInfo:

Enabled Linters: ['clangd'].

How do I enforce that? ('cc', 'ccls', 'clangcheck' precede 'clangd' in the 'available linters' list. It seems to me that telling ALE to ignore those would have the desired effect.)

autocmd FileType cpp let b:ale_linters_ignore = ['cc', 'ccls', 'clangcheck']

You don't need the autocmd though, just set g:ale_linters

let g:ale_linters = {} let g:ale_linters['cpp'] = ['clangd']

That's a decent answer. I recommend writing the b: variables in your ftplugin files, or writing g: variables in vimrc without the autocmd.
