fasthash-sys build fail for target x86_64-unknown-linux-musl

[jolisper]

I'm trying to build my crate for a musl based linux (alpine) and when I run:

$ cargo build --target=x86_64-unknown-linux-musl

on master branch, shows the following output:

   Compiling fasthash-sys v0.3.1 (/home/jorge/src/almundo/rust-fasthash/fasthash-sys)

error: build failed

The problem is the same using stable and nightly toolchains.

Any idea how to fix this? Or how to proceed in order to build this crate for musl target?

< utility > is part of C++ stdlib, it seems you missed musl C++ support?
