Plrustc will not compile on alpine/postgres. #372
Description
I get this output when running the build script for plrustc:
3.516 + env 'RUSTFLAGS=-Clink-args=-Wl,-rpath,/usr/local/rustup/toolchains/1.70.0-x86_64-unknown-linux-musl/lib/rustlib/x86_64-unknown-linux-musl/lib -Zunstable-options -Zbinary-dep-depinfo' cargo build --release -p plrustc --bin plrustc --target x86_64-unknown-linux-musl

I looked in the library path, and indeed many rlibs are missing.

I don't know if this will help, but for alpine you almost always need:
before you start compiling anything. Give that a shot. Offhand I don't know if
plrustc/build.shmight need to be updated or if you can handle it directly in your Dockerfile.therealjasonkenney commentedon Aug 11, 2023
Thanks, I managed to get it all compiled, mostly by not using
plrustc/build.shand manually adding a json file to postgrestd. However a new problem arrises, how do I get those rust flags to be used when Postgres compiles a rust function?workingjubilee commentedon Aug 21, 2023
Proper support would involve threading full support for a musl libc distro in all locations.
