Issue linking with arm64 and musl (Alpine 3.18) #1003

Closed Fishrock123 closed 7 months ago

Fishrock123 commented 7 months ago

Building git2 causes an issue when build for Alpine linux 3.18 targeting arm64.

See this rustc issue: https://github.com/rust-lang/rustup/issues/3324#issuecomment-1850958704 - I am not sure if this is a rust compiler issue of an issue with e.g. libgit2-sys, but it seems more likely that it is a crate issue.

Here is my linking error:

Thanks for the report! I'm going to close as a duplicate of #706 and https://github.com/rust-lang/rust/issues/89626. Unfortunately I don't think there is anything this library can do to fix the issue. https://github.com/rust-lang/rust/issues/89626 contains some workarounds.
