While installing RNPermissions and its dependencies I run into an error. Seems to be a problem with my compiler or the package that is being installed.

The error: 

checking whether the C compiler works... no

For me running sudo xcode-select --reset fixed it.

Prior I also installed/updated gcc with brew upgrade gcc, not sure if this a prerequisite.

Set your XCODE CLI via XCode preferences and then run pod install again.

Xcode -> Preferences -> Locations -> Command Line Tools

Had the same issue, slightly different output. Resolved by accepting Xcode license sudo xcodebuild -license accept

Ensure Xcode is in your Applications folder.

I had to install an old version of Xcode and was just running it out of ~/Downloads. Once I moved (cut/paste) the Xcode.app file to Applications, this error went away.

  • I had a similar situation going on. Instead of the executable being named "Xcode.app" is was named "Xcode 13.app", which meant the compilation process was not able to find it. Renaming from "Xcode 13" to "Xcode" solved my problem. – Antonio Jaime Oct 06 '22 at 16:42

Updated GCC and the problem went away.

brew update
brew upgrade
brew info gcc
brew install gcc
brew cleanup

I tried the laundry list of suggestions, and found a non-ideal workaround from here: https://github.com/facebook/react-native/issues/32291#issuecomment-929965479

I executed which gcc and used that path on the export CC line in the script referenced above.

Of course, editing directly in node_modules isn't the best way to do it, as it'll be blown away with any updates, but it at least allowed the pod install to complete.
