Verification

• I ran brew update and am still able to reproduce my issue.
• I have resolved all warnings from brew doctor and that did not fix my problem.

What were you trying to do (and why)?

I am trying to build a Cython module in macOS 13 and gcc-12 (12.2.0). However, the headers are not found since gcc assumes that macOS 13 SDK is available (found through gcc -v, see below). This SDK is still in beta afaik so how can I resolve this?

Also note that 'brew doctor' warns to upgrade Xcode to 14.1 and the CLT however, these are both still in beta. So what should be done when one is not an Apple Developer and hence, how to resolve the brew doctor warning?

The SDK was supposed to be released at the same time but a last minute issue caused RC 2 to be released instead. This surprised us as well, as that has never happened before.

We don't support development tools without a SDK matching the running macOS so you'll need to install Command Line Tools for Xcode RC 2 from developer.apple.com (free - doesn't require to be in the paid program) or wait for it to be released, which is hopefully very soon.

Thanks for the answer. For those running into these issues, instead of using Xcode 14.1 RC 2, you can also just download the SDK here: https://developer.apple.com/download/all/

[Bo98]

14.1 RC 2 should still contain the macOS 12 SDK if you need that. Though earlier versions also work on macOS 12 so 14.1 RC 2 isn't a requirement for that.

[kenju]

For those who encounter the similar issue, let me share few more tips to solve this.

As @paulmadejong suggets, you'll have to download Command Line Tools for XCode 14.1 Release Candidate 2 from https://developer.apple.com/download/all/

Once you download and installed the tools, you'll find that command line tools are installed at /Library/Developer/CommandLineTools/usr/bin directory.

 ls -l /Library/Developer/CommandLineTools/usr/bin/ | wc -l
     114

Especially, you'll find clang there.

$ /Library/Developer/CommandLineTools/usr/bin/clang -v
Apple clang version 14.0.0 (clang-1400.0.29.202)
Target: x86_64-apple-darwin22.1.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

That might be linked to /usr/bin/clang now, if set the path manually.

$ /usr/bin/clang -v
Apple clang version 14.0.0 (clang-1400.0.29.202)
Target: x86_64-apple-darwin22.1.0

You might have Xcode 14.1, but you definitely don't have "Command Line Tools for Xcode 14.1".

[zerobytes]

You're right.
Just downloaded the command line individually and installed. Now it seems to be running.
Thank you @Bo98

[shish]

you'll need to install Command Line Tools for Xcode RC 2 from developer.apple.com (free - doesn't require to be in the paid program) or wait for it to be released, which is hopefully very soon.

Looks like a week later it's still not released, and https://developer.apple.com/download/all/ redirects me to https://developer.apple.com/account/ with a "Join the Apple Developer Program" prompt :(

Has anyone managed to download the command line tools without joining the program, if so is there some other link to it that I'm just not seeing?

[carlocab]

You'll need to register to download it, unfortunately. Registration is free, however.
