Need Clang version at least 16

Question

I am tried to compile the Apache Doris on macOS 13.3.1 follow by this document: https://doris.apache.org/docs/install/source-install/compilation-mac/. When I run the bash build.sh command, shows error like this:

I have tried to upgrade the clang version to 16 and this is the current clang version with my macOS system:

> clang --version
clang version 16.0.6
Target: arm64-apple-darwin22.4.0
Thread model: posix
InstalledDir: /opt/local/libexec/llvm-16/bin

Am I misssing something? what should I do to fixed this issue? I also tried to use the brew version:

> clang --version
Homebrew clang version 18.1.7
Target: arm64-apple-darwin22.4.0
Thread model: posix
InstalledDir: /opt/homebrew/opt/llvm/bin

maybe the app still using the old version /usr/bin/clang.
