  Hi AJ 7885. I ran into a similar issue and was able to resolve using:

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

  If you get any permissions issue, then use:

  sudo gem install thin -- --with-cflags="-Wno-error=implicit-function-declaration"

  I'm guessing it may have to do with a newer version of XCode elevating certain compile-time issues to error level.

  Side note: there's a beta version of a newer command line tool (zcli) that removes Ruby and Ruby Gems from the picture (zat) as it's written in Node.js. It will be more cross-platform friendly (especially for Windows users). It's still in beta, for a release sometime next year. If you want to check it out, see: https://developer.zendesk.com/apps/docs/developer-guide/zcli

  PS — I got the compile-time workaround above on StackOverflow.

  Hello Bryan, 

  Thank you for your help, unfortunately it still not working. 

  Do you think i need a downgrade for Xcode  from Version 12.0 (12A7209) ? 

  Im using gem 3.1.4

  Thank you for your help

  Are you getting the exact same errors when running this?

  sudo gem install thin -- --with-cflags="-Wno-error=implicit-function-declaration"

  I'm on 12.0.1 of Xcode and 10.15.6 of macOS. I wouldn't recommend downgrading.

  3.8.1 is the latest version of zendesk_apps_tools, so if you're on 3.1.4, getting the newer one installed is definitely recommended.

  Modifying my previous post: try including the version number of the "thin" gem if running into build issues around it:

  gem install thin -v 1.7.2 -- --with-cflags="-Wno-error=implicit-function-declaration"

  The "zendesk_apps_tools" gem has a dependency on thin version 1.7.2. Without specifying a version, the later version of thin (v1.8.0) will get compiled instead by default.

  I'm having the same issue as above. Doing 

  gem install thin -v 1.7.2 -- --with-cflags="-Wno-error=implicit-function-declaration"

  Works without error but I'm not able to do gem install zendesk_apps_tools and zat doesn't work

  Same problem on Mac OS Big Sur, installing the new version of zat called zcli worked for me.

  Bryan,

  I suggest you all add this information:

  gem install thin -v 1.7.2 -- --with-cflags="-Wno-error=implicit-function-declaration"

  The "zendesk_apps_tools" gem has a dependency on thin version 1.7.2. Without specifying a version, the later version of thin (v1.8.0) will get compiled instead by default.

  to this post: https://develop.zendesk.com/hc/en-us/articles/360001075068

  I imagine that's impacting many users with Mac OS Big Sur like myself.

  Agreed Autumn Grassel. I put in a request to get that KB article updated with this point.
