This is because the cc-rs crate adds a hash to the generated object file name to avoid collisions if there is another file in a subdirectory with the same name.

Should be fixed by #39

Same error, what's the work around for this?

In my project, which depends on rust-llama.cpp, I fixed this by pinning the upstream cc dependency in my Cargo.toml:

[dependencies]
cc = "=1.0.83"
