disabling the error fixed it:

bundle config build.thin --with-cflags="-Wno-error=implicit-function-declaration"

I hit this same error as well and your config line worked, so thanks! However I am wondering if disabling the error is the best solution, as the error could be occurring because of a legitimate issue. Any thoughts? – Fralcon Sep 21 '20 at 23:51

this is a temporary fix. see https://stackoverflow.com/questions/63278694/thin-and-puma-fail-with-similar-issues-error-failed-to-build-gem-native-exten for the explanation. it looks like the issue has been fixed in the master branch of thin, see https://github.com/macournoyer/thin/issues/370 – subelsky Oct 06 '20 at 20:50

The solution that worked for me was slightly different. I had to run the following for my specific gem version, using rbenv on Big Sur 11.3.1. I added a more in depth explanation of my particular error and solution here.

gem install thin -v '1.6.4' -- --with-cflags="-Wno-error=implicit-function-declaration"
