2 years ago (taichi-dev) ➜ taichi git:(master) clang --version
Apple clang version 13.0.0 (clang-1300.0.29.3)
Target: x86_64-apple-darwin20.6.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/binI believe it's the builtin clang of macOS if my memory is not wrong.

2 years ago Yeah, this is possibly a compatibility issue between LLVM-10 (kind of old) and clang-13. Will look into it

2 years ago Seems clang-13 with llvm-10 on ubuntu has a different error

2 years ago This is probably because LLVM IR is not guaranteed to be forward compatible. So old llvm-as may not be able to parse the IR generated by new clang. Seems llvm 12 break the compatibility. Since clang on MacOS strongly relies on the system tool-chain, we may not be able to provide a single binary now (the binary from the LLVM official site may not work too). Also found a similar issue here.
The current recommended solution is to downgrade clang to a version no greater than 11 (10 is better) using brew/MacPorts or maintain multiple xcode tool-chain.
Will update doc and add version checks in cmake.

2 years ago have the same problem with clang10 and llvm10
ubuntu@ubuntu:~/taichi$ clang --version
clang version 10.0.0-4ubuntu1
Target: aarch64-unknown-linux-gnu
Thread model: posix
InstalledDir: /usr/binhave the same problem with clang10 and llvm10
ubuntu@ubuntu:~/taichi$ clang --version clang version 10.0.0-4ubuntu1 Target: aarch64-unknown-linux-gnu Thread model: posix InstalledDir: /usr/bin
Could you provide the complete commands and errors in your building?
When I follow this doc to build Taichi https://docs.taichi.graphics/lang/articles/contribution/dev_install#installing-dependencies under macOS 11.6 and pre-prebuilt llvm 10.0.0
