unable to compile on aarch64 musl

[ManOrs88]

hello, I'm unable to (cross)compile a musl binary on aarch64 ("cross" as in from ubuntu, still aarch64) [also tried compiling native on alpine aarch64, same result]

$ cargo install --target aarch64-unknown-linux-musl fclones

help: you can convert a `u64` to an `i32` and panic if the converted value doesn't fit

error: could not compile `reflink` due to previous error

compiling with glibc works correctly

(rust 1.57.0)

The reflink master (already 2 years old) has a fix for that, try using that one instead of the one from crates.io by changing the reflink = "0.1.3" line in Cargo.toml to reflink = { git = "https://github.com/nicokoch/reflink.git", rev = "e8d93b465f5d9ad340cd052b64bbc77b8ee107e2" }

Also happens with cargo build in Debian armhf/arm7vl (Raspberry Pi). Dunno if this is relevant but just putting it here for search engines.

Using the reflink (check out the repo, change Cargo.toml as above, do a cargo build --release ) works.

Is there any reason fclones isn't using that version?

[pkolaczk]

It is not possible to publish a crate that relies on an unpublished crate. All dependencies must be in crates.io.

RE: Piotr

Oh I see, that's just perfect 😆

Through the magic of #[cfg(..)] reflink should not bother you any longer!

Unless you want to test fclones... I only left reflink active in the Linux build to test the macOS/Windows code paths, but these need not be build for the fclones binary itself.
