'linter' package in atom installed with 'linter-gcc' for C linting not responding

I am aware that XCode could be part of the issue from this link. I've tried putting the correct path into the linter-gcc settings in atom, adding /bin/gcc-9 at the end of the path, restarting atom after every attempt. I have deleted XCode before attempting once more. I installed homebrew and manually installed linter-gcc manually as the link implies as well. I'm wondering if there are left over files from XCode that are could be interfering with the linter still.
