Could you please file a bug report and CC me? I'll try to submit a patch next week but would appreciate a reminder :) In my projects and toolchain files I always used xcrun to query for the SDK path: $ xcrun --sdk macosx --show-sdk-path /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk The xcrun approach has the advantage that it respects the DEVELOPER_DIR environment variable and thus works with different Xcode installations.
