[oxigraph_server] Add rocks db?

I've tried a few different env vars to try and point it to clang, but cannot resolve the error:

[03:27:54]   thread 'main' panicked at 'Unable to find libclang: "the `libclang` shared library at /opt/x86_64-linux-musl/lib/libclang.so.12 could not be opened: Dynamic loading not supported"', /opt/x86_64-linux-musl/registry/src/github.aaakk.us.kg-1ecc6299db9ec823/bindgen-0.57.0/src/lib.rs:1975:31

@giordano Hope it is ok to ping you, I've tried every incantation I can come up with, but it doesn't want to use the libclang Yggdrasil provides and would be grateful for your feedback / a nudge in the right direction. :)

Do you really want to depend on Clang_jll? It's a massive complication, you'd need to do different builds for each Julia version.

[jeremiahpslewis]

If I can find a way to not need Clang_jll, then I'm all for it. It seems like the root cause of the issue is rust-lang/rust-bindgen requiring clang at compile time. It seems like BinaryBuilder should support this, but maybe I'm missing something.

• libclang not found when building using github actions for windows target rust-lang/rust-bindgen#1797
• Error related to bindgen when building on alpine tikv/grpc-rs#477

@giordano Do you have a guess as to whether this is fundamentally hopeless (because clang-sys is incompatible with BinaryBuilder / other rust idiosyncrasies or whether there's a route that I'm failing to see and could explore?

It seems weird that rocksdb wouldn't be buildable by BinaryBuilder, but perhaps I should go a step back and try and build rocksdb separately?

[giordano]

Yeah, the error

[15:38:58]   thread 'main' panicked at 'Unable to find libclang: "the `libclang` shared library at /workspace/destdir/lib/libclang.so.13.0.0jl could not be opened: Dynamic loading not supported"', /opt/x86_64-linux-musl/registry/src/github.aaakk.us.kg-1ecc6299db9ec823/bindgen-0.57.0/src/lib.rs:1975:31
[15:38:58]   note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

doesn't look like this is going to work. Not this way at least, I don't think we build static libraries for Clang

Thanks
