Unable to build on arm64 mac

[nevinpuri]

I've been trying to build chdb on my mac to use as a python library (as your version 1.0.2 doesn't have an arm64b build), but I've been having trouble building it. I've installed clang via homebrew, but I'm getting an error Could not find compiler set in environment variable CC. I'm not sure why it's looking for clang in /usr/local/opt/llvm/bin/clang, as I explicitly set CC=/opt/homebrew/opt/llvm/bin/clang and CXX=/opt/homebrew/opt/llvm/bin/clang.

If anyone has any ideas, any help is appreciated.

Make sure that git diff result is empty and you've just pulled fresh master. Try cleaning up cmake cache. Just in case, official build instructions are published here: https://clickhouse.com/docs/en/development/build/

Operating system

MacOS Sonoma 14.0

OS kind or distribution, specific version/release, non-standard kernel if any. If you are trying to build inside virtual machine, please mention it too.

If there is no /usr/local/opt/llvm/bin/clang Try make symbol link /usr/local/opt/llvm to /opt/homebrew/opt/llvm

version 1.0.2 doesn't have an arm64 build

We have an aarch64 build and you can use our docker builde to generate custom builds locally.

I managed to get the build to work by modifying the build.sh file. However, it wouldn't install. I'll just use v1.0.0 and patch the python file.
