Difficulty building on M1 mac #81

Open rob-p opened 2 months ago

Hi @jguhlin,

I encounter the following error when attempting to include the minimap2-rs crate when building on OSX on an M1 Mac (MacOS 13.4):

  = note: ld: warning: directory not found for option '-L/Users/rob/software_src/oarfish/target/release/build/libz-sys-388cc2f2b07c10b2/out/lib64'
          Undefined symbols for architecture arm64:

          ld: symbol(s) not found for architecture arm64
          clang: error: linker command failed with exit code 1 (use -v to see invocation)

Have you seen anything like this before? Any idea why the relevant libz functions might not be found?

Thanks!

I was able to get this to compile by manually overriding the rust flags (as below), but that shouldn’t be necessary. Any ideas why?

RUSTFLAGS=‘-C link-args=-lz’ cargo build —-release

Hmm that should be a change we can make in build.rs script for it.

I don't have a Mac to test on, but will take a stab at it soon
