Hi I get a strange warning on MacOS when I do ./configure:
checking Xcode version... xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance not found (too old?) I also get a related strange warning when I do a compile: ghc hello.hs [1 of 2] Compiling Main ( hello.hs, hello.o ) [Missing object file] [2 of 2] Linking hello [Objects changed] ld: warning: directory not found for option '-L/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX12.1.sdk/usr/lib' I'm on macOS 13.2.1. I was previously on ghc 9.4.4.
