It seems wrong to me that the configure file references Xcode.app and MacOSX12.1:

bash-3.2$ fgrep Xcode.app configure

FFIIncludeDir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX12.1.sdk/usr/include/ffi

FFILibDir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX12.1.sdk/usr/lib

Hi Ben

Thanks for replying.

As I mentioned in my original email I'm on Ventura,13.2.1, I just upgraded to that before installing alpha3.

I have command line tools. I did the following to reinstall them and got the same results stated in my email:

 sudo rm -rf /Library/Developer/CommandLineTools

Password:

bash-3.2$ xcode-select --install

xcode-select: note: install requested for command line developer tools

Looking more carefully at the error message:

checking Xcode version... xcode-select: error: tool 'xcodebuild' requires

It seems to be saying that I need Xcode not command line tools. That's also consistent with the linker warning message:

ld: warning: directory not found for option '-L/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX12.1.sdk/usr/lib'

There is no urgency on my part to get this resolved. We may want to just wait to see if anybody else on 13.2.1 got this also.

Thanks

George

Hmm, that is indeed odd. It sounds like you Xcode installation may be
broken. Did you upgrade your operating system recently? Do you have
Xcode, the CLT package, or both installed?
