Hello, I tied to compile a simple hello.c program using clang on the DTK. It complains:

/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/sys/cdefs.h:807:2: error: Unsupported architecture

Wondering how to fix this.

This is working for me:

Code Block  % sw_vers 
ProductName:	macOS
ProductVersion:	11.0
BuildVersion:	20A5374i
% cc hello.c 
… some meaningless warnings …
% ./a.out
Hello Cruel World!

One thing to check is that you have the latest Xcode installed (12.2b1) and that it’s currently selected:

Code Block  % xcode-select -p
/Applications/Xcode-beta.app/Contents/Developer
% plutil -p /Applications/Xcode-beta.app/Contents/Info.plist | grep 'CFBundle.*Version'
  …
  "CFBundleShortVersionString" => "12.2"
  "CFBundleVersion" => "17512.1"

Thank you Quinn. After doing the Beta 9 update (no easy feat) and downloading Xcode 12, it worked.
