Can't compile zlib-ng feature on M1 Mac

[stjepangolemac]

I've opened a similar issue here rust-lang/flate2-rs#318

I'll close one of them as soon as I figure out the right place for it.

flate2 = { version = "=1.0.24", default-features = false, features = ["zlib-ng"] }

Compiling with that feature returns this:

error: failed to add native library <redacted>/target/debug/build/libz-ng-sys-9e9c491639259674/out/lib/libz-ng.a: file too small to be an archive

Compiling with zlib-ng-compat fails too but returns a lot more output:

Error output

I've tried installing zlib-ng through homebrew but it didn't help.

It looks like the C compiler your system is using defaults to x86-64 targets, rather than aarch64 targets? What C compiler is it trying to use?

[joshtriplett]

Is it possible you're hitting rust-lang/rustup#3068 ?

[stjepangolemac]

I have no idea as I've wiped my machine months ago and haven't seen this since 🤷

@stjepangolemac Alright. I'm going to close this, but if you run into something again, please do raise an issue or ask for this one to be reopened.
