@rocky have you tried this command?
open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg

To fix it in Catalina, set the correct headers path in .bash_profile:
export SDKROOT=“$(xcrun --sdk macosx --show-sdk-path)”
(/Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.15.pkg is not available in Catalina).
… and then recompile the deps.

I got this error on a fresh install, first time in over a year, and your suggestion removed the error. Thanks.

[error] Can't find executable `mac_listener`
[warn] Could not start Phoenix live-reload because we cannot listen to the file system.
You don't need to worry! This is an optional feature used during development to
refresh your browser when you save files and it does not affect production.

Hey friends,
I had the same issues as most folks above (macOS Sonoma 14.3.1) and none of the solutions worked, even reinstalling xcode, command line tools, etc.
What I ended up doing and what worked is the following inside deps/file_system:
xcrun clang -isysroot $(xcrun --show-sdk-path) -I$(xcrun --show-sdk-path)/usr/include -framework CoreFoundation -framework CoreServices -Wno-deprecated-declarations c_src/mac/*.c -o priv/mac_listener
So basically:
$(xcrun --show-sdk-path): Ensures the compiler knows where to find the system SDK.-I$(xcrun --show-sdk-path)/usr/include: Specifies where to find include headers (probably redundant with the SDK setting
).-framework CoreFoundation -framework CoreServices: Links necessary Apple frameworks.c_src/mac/*.c -o priv/mac_listener: Compiles all C files in the specified directory and outputs the executable asmac_listener.
And with the mac_listener in place, it worked fine.
