I am try to compile https://github.com/aptos-labs/aptos-core in x86 64-bit x32 ABI environment, then stuck on librocksdb-sys. Trace to bindgen, then found the problem is on clang-sys.

BTW, you could try to get x32 ABI environment by use docker image xddxdd/debian-x32 easily.

EDIT: oh no, I was using x86_64-unknown-linux-gnu toolchain.

Closing for not sure this issue is valid or not.
