Building on Mac OS

[ocschwar]

"cargo install alert-after" fails as follows right now:

= note: Undefined symbols for architecture x86_64: "_LSCopyApplicationURLsForBundleIdentifier", referenced from: _setApplication in libmac_notification_sys-29e1c5fea20af7d3.rlib(notify.o) ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

What version of macOS are you running?

[ocschwar]

Yosemite 10.10.5. Just ran rustup and tried again. Same error.

This doesn't resolve this issue, but for posterity, here's a similar issue:

bazelbuild/bazel#1875

[zanedev]

failing on macos sierra for me doesnt look like same error, new to rust and cargo here so not sure how to troubleshoot it.

The original issue here by @ocschwar is pretty straightforward to understand: using a version of macOS that doesn't support the APIs we rely on. This could either be addressed by attempting to make the mac-notification-sys crate more backwards compatible, or just indicating in the alert-after documentation that we only support version 10.11 and above.

Regarding @zanedev's issue, I'm not sure at all what's going on there.

cargo:warning=/opt/local/bin/ranlib: object: /var/folders/vt/8fqn0xmn4cjd99v95sgzh98m0000gn/T/cargo-install.3T4mP25j5Sic/release/build/mac-notification-sys-69e567e5a4462529/out/libnotify.a(notify.o) malformed object (unknown load command 4)

This in particular is very weird. No idea :-/
