Does it work if you do the same with XCode 15?
Perhaps I'm missing something but to me it doesn't look like the
right/supported way of compiling PostgreSQL on this platform [1]. I
tried to figure out what version of Xcode I'm using right now, but it
seems to be none:
$ /usr/bin/xcodebuild -version
xcode-select: error: tool 'xcodebuild' requires Xcode, but active
developer directory '/Library/Developer/CommandLineTools' is a command
line tools instance
Clang I'm using doesn't seem to be part of XCode distribution either:
$ clang --version
Homebrew clang version 18.1.6
Target: x86_64-apple-darwin23.5.0
Thread model: posix
InstalledDir: /usr/local/opt/llvm/bin
It's been a while since I installed all the dependencies on my laptop,
but I'm pretty confident I followed the documentation back then.
IMO the right way to test PostgreSQL against the recent beta version
of MacOS SDK would be replacing (via a symlink perhaps) the SDK
provided by the "Command Line Tools for Xcode" package
(/Library/Developer/CommandLineTools/SDKs/). Or alternatively finding
the official way of installing the beta version of this package.
