For supported x86_64 GCC versions (at present 12 and trunk) on macOS12. It is usually easiest to install the Xcode Command Line Tools - the SDK path is then /Library/Developer/CommandLineTools/SDKs/MacOSX12.sdk then add the following to your configure line: —with-sysroot=/Library/Developer/CommandLineTools/SDKs/MacOSX12.sdk If you want to use the set in Xcode then add the following to your configure line: —with-sysroot=`xcrun --show-sdk-path` I prefer/recommend the first option.
