I am developing C code on Ubuntu 20.04.

By running cppcheck -q --project=build/proj1/compile_commands.json --file-filter='src/base/Myfile.c'

I got the error

cppcheck: error: unrecognized command line option: "--file-filter=src/base/Myfile.c".

It looks like the version of cppcheck included in Ubuntu 20.04 is not the latest:

$ apt show cppcheck | grep Version
Version: 1.90-4build1

cppcheck 1.90 was released in 2019. The --file-filter argument was introduced in commit fcd5cda97 in 2020:

$ git show fcd5cda97f10085c7def7fda6fc6199f624010ce
