This is a very strange error, from far it looks like a botched install of the macOS dev tools. I have the same kind of configuration and dune.3.11.1 installs fine. Could you maybe output the results of opam config report and env to see if there’s maybe something suspicious.

Do you have C_INCLUDE_PATH set to something by any chance ?

EDIT: It seems there have been problems with compiling this file see fix: re-enable dune on older macos sdk's by rgrinberg · Pull Request #6515 · ocaml/dune · GitHub

Maybe try to update xcode ?

I’m dont use xcode
.

You need to have some kind of c compiler installed. Usually that comes with xcode on Mac. And was likely installed when you setup homebrew.
You already have xcode command line tools. (C compiler, headers etc).
Ie. the files located in /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk
Try

ls -l /Library/Developer/CommandLineTools/SDKs

and

 echo "" | gcc -xc - -v -E
ls -l /Library/Developer/CommandLineTools/SDKs

Make sure your sdk is updated too if you upgraded OSX to Catalina. I.e. check software update.

A few things to check as well:

brew doctor

Other than that I don’t have any ideas. Last resort is reinstalling Xcode command line utils client.
