Inline suppression of unusedFunction errors not working when using compile_commands.json

[Viktor Kajml]

Hello,
I cannot get inline suppression of unusedFunction errors to work when passing compile_commands.json to cppcheck. It works alright when I just pass a list of files, or when using the --suppress-xml or --suppressions-list arguments.

It just doesn't work for:

• unusedFunction errors

• when using compile_commands.json

• when using inline suppression

I'm attaching a minimal example:

If I run (inside the minimal-example folder):

cppcheck --project=compile_commands.json --enable=all --inline-suppr

I get an unusedFunction error.

If I run:

cppcheck --project=compile_commands.json --enable=all --suppress-xml=suppressions.xml --inline-suppr

or

cppcheck --enable=all --inline-suppr example.c

I don't get any errors.

Could this be a bug? Or is there a way to get inline supporession working when using the compile commands file?
