C compiler cannot create executables (installing Cocoapods)

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

Try `/Users/si/Library/Caches/CocoaPods/Pods/Release/glog/0.3.4-1de0b/missing --help' for more information

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

Additionally you may need to run first brew install gcc or brew upgrade gcc.

An edge case that caused this error for me is where the Xcode application path has a blank space in it.

In my case I had to rename /Applications/Xcode\ 14.2.app to /Applications/Xcode14.2.app, and of course update Xcode's location with sudo xcode-select -s /Applications/Xcode14.2.app.

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.

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.

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
