How to statically compile OpenSSL with crane (static-musl example)?

[hidrol]

Hi everyone,

I'm trying to statically compile my Rust project with OpenSSL using naersk and the static-musl example from the repo.

However, I'm not sure how to add OpenSSL in a way that works with musl and static linking. I tried adding pkgs.openssl but it either fails to link or complains about missing symbols.

Has anyone successfully linked OpenSSL statically in this setup? I'd really appreciate any pointers or a working flake.nix snippet.

Thanks in advance!

Are you linking aginst pkgs.pkgsStatic.openssl? The pkgs.openssl doesn't have a static version, I think.
