Building with a skia renderer fails with a git error on Intel Mac about slint

[tronical]

Could you describe your build environment a little? It looks like there's an issue with the Xcode installation. Note the following two error messages from your log:

xcrun: error: unable to lookup item 'PlatformVersion' from command line tools installation
xcrun: error: unable to lookup item 'PlatformVersion' in SDK '/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk'

What does xcrun --show-sdk-path --sdk macosx show for you? Does the directory it prints exist and have an SDK installed?

Perhaps you may want to switch to the default SDK using sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer ?

@tronical Running xcrun --show-sdk-path --sdk macosx outputs /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk. It does have an sdk installed.
As for ninja, I installed it from homebrew

Thanks for the quick response. Could you also try running xcrun --show-sdk-platform-version?

[mitioshi]

@tronical Sure. Here's what it prints

▶ xcrun --show-sdk-platform-version
xcrun: error: unable to lookup item 'PlatformVersion' from command line tools installation
xcrun: error: unable to lookup item 'PlatformVersion' in SDK '/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk'

Ok, and that's the source of the build issue you're seeing. This command should not produce the error but print a version. It looks like the macOS SDK installed in /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk on your machine is incomplete somehow (or corrupted).

[tronical]

Could you run ls -ld /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk? I wonder what your MacOSX.sdk symlink points to. It looks like 10.7 maybe? Do you have an explicit macOS deployment target configured?

[mitioshi]

Do you have an explicit macOS deployment target configured?

I don't. Here's where the symlink points:

▶ ls -ld /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk
lrwxr-xr-x  1 root  wheel  14 Feb  7 12:46 /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk -> MacOSX14.2.sdk
▶ realpath /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk
/Library/Developer/CommandLineTools/SDKs/MacOSX14.2.sdk

[tronical]

Thanks. I can reproduce this. It seems that xcrun --show-sdk-path --sdk macosx is not supported with the command line tools alone (see also rust-lang/cc-rs#1001). If you run sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer the issue should be resolved and the build should work.

I'll add this to the known issues docs for the Skia renderer build.
