Trouble setting up ccls

[AbrA-K]

I've been trying to set up ccls for platformio development and I keep having issues with the lsp. If I'm honest, I'm not quite sure if It's the lsp or my helix config that's the problem, but maybe someone has similar issues.

This is in my language.toml:

[[language]]
name = "c"
file-types  = ["c", "h"]
roots = [".ccls"]
language-servers = ["cc-ls"]

[language-server.cc-ls]
command = "ccls"

... which will spit out this error message:

other than Async job failed I really don't know what to look out for and what the issue may be. Some errors from the lsp really don't seem like errors to be honest.. The .ccls is autogenerated and should be fine - that's at least my hope:

[AbrA-K]

The .ccls is probably wrong. I made a minimal test to test out ccls:

# .ccls
gcc

(and a simple main.c)
in my test it works like expected. I'll try to figure out what's wrong with the autogenerated .ccls.

also got my other Project working:

gcc # clang would probably work too

#%c -std=gnu11 -fno-fat-lto-objects -mmcu=atmega644a -Os -Wall -ffunction-sections -fdata-sections
%c -std=gnu11 # the above was the Problem: this flag is the only one that didn't screw up the lsp

#%cpp -Wno-error=narrowing -fno-exceptions -fno-threadsafe-statics -fpermissive -std=gnu++11 -mmcu=atmega644a -Os -Wall -ffunction-sections -fdata-sections -flto
