Failed to install on Fedora 38(aarch64)

[Qinka]

I use fedora 38 (aarch64). Get error output:

error: failed to run custom build command for `loopdev v0.4.0`

Caused by:

@Qinka This is a known problem (see #63 ) and will be resolved in the next loopdev release. If you are building a project that depends on loopdev via cargo you can do a temporary fix like the one here: stratis-storage/libcryptsetup-rs#283 .

[mulkieran]

For completeness sake, the rust-loopdev package in Fedora installs because it's been patched to update its bindgen dependency, see koschei log[1] for the record of builds of the package.

So, that your build is failing indicates to me that you're probably using the "cargo-install" command or something to build something which relies on the loopdev crate from source.

There is more information on the cause of the bug here: rust-lang/rust-bindgen#2488 .

[mulkieran]

@Qinka We decided to fork the project here: https://github.com/stratis-storage/loopdev-3/releases/tag/loopdev-3-v0.5.0 . It will resolve the problem you experienced.

Could you please mention this at & crate's main page ?

Can't do that, because I have no control over that page. There is an advisory that the crate is unmaintained, though. https://rustsec.org/advisories/RUSTSEC-2023-0088.html .
