Wrong type argument: listp, "-Wall -Werror"
Did you specify -Wall -Werror in compile_commands.json or .ccls?
This choice, in order to avoid providing any
compile_commands.jsonand/or.cclsfiles to facilitate debugging.
Neither compile_commands.json nor .ccls is mandatory. See https://github.com/MaskRay/ccls/wiki/Project-Setup But ensure (lsp--suggest-project-root) return the correct project root.
A minimal example is: mkdir /tmp/c; cd /tmp/c; git init; echo 'int a;' > a.cc
Open a.cc, and execute M-x lsp
from emacs-ccls.

Thank you for your quick answer.
I have created the ccls file at /tmp/c that contains the following content:
clang
%c -std=c11
-Wall
-Werror
NOTE: I started from your example and I did not generate the recommanded compile_commands.json file with CMake since this folder does not have a CMakeLists.txt file.
However, after restarting GNU Emacs, opening the /tmp/c/a.cc file and execute M-x lsp, but the error is still the same.
As requested, I have checked that the (lsp--suggest-project-root) function returns the right path. To do this, I changed the mode of the file for lisp-mode and executed this function that sends me back: "/tmp/c/"
If it can help:
M-x emacs-version

-Werror
Unrelated to this issue report, but just wanted to mention that -Werror is probably not the flag you want to add to .ccls. If for some reason clang cannot parse your source file (sometimes due to gcc compatibility, sometimes due to clang's own bugs when some clang features like preamble being used), By default, clang stops parsing the file when it encounters 19 errors (cc1 flag: -ferror-limit 19).
M-x toggle-debug-on-error and try again.

This is what M-x toggle-debug-on-error provides me after opened back the /tmp/c/a.cc file:

NOTE: I generally use gccto compile my .c and .cpp files, so I changed clang for gcc in the .ccls file. However, clang a.cc works fine in a terminal.
This is the .ccls file with these modifications:
gcc
%c -std=c11
-Wall
One thing I don't understand is how and why I have to provide the -Wall and -Werror flags if I haven't specified to use them everywhere.
In fact, these flags are only defined as compilation options in a CMakeLists.txt file that I specified in another C++ project (sfml-game) where I also tried to use lsp-mode and ccls. That's why, I tried with a minimal project, in vain.

ccls-args is a list of strings. Don't use (setq ccls-args "-Wall -Werror")

A huge thank you for your patience and help. Indeed, the arguments of ccls-args was the error. I wonder how it could have been redefined because I don't use it anywhere in my GNU Emacs configuration.
