Discussion:
Describe the bug upgraded to 2.0.0, but this version is broken on darwin: It appears this is because ' macOS SDK is 10.12, but the symbols that cause problems in 2.0.0 are only available in 10.13+:
Issue regarding newer SDK
I'm also seeing watchdog as a blocker for installing some packages. e.g., installing was-sam-cli is broken: Any work-around or fix?
Still happens with watchdog
Yeah, unfortunately, I think nothing is going to change on this issue until someone has time to upgrade the macOS SDK ()
That's happening at as part of
What if the package uses sdk_11 for now?
It needs , so maybe fine.
Talking to this doesn't seem so simple. The 11 SDK is only available through the Aarch64 stdenv IIUC. So maybe this package doesn't need to be marked broken for Aarch64 Darwin, could someone using native Nix on an M1 mac confirm this? Making it available on x86_64 properly would entail as much work as bumping the SDK to 10.13 does because we have as much as possible depend on the Apple source releases rather than the SDK. So I don't think this'd be an easy workaround. would be better able to judge how practical the idea is though.
<details<summaryHere's what I tried, from a checkout of master: </summary</detailsI suspect the problem is trying to with the 10.12 darwin-stubs, which could explain missing dylibs. The usual 10.12 expression explicitly depends on but does not so I'm not able to override it. I'm not sure why this is,
Maybe it's using impure stubs from the host? Would be cool if someone running Big Sur could confirm or deny whether the above works for them.
I ran into the same issue on Big Sur.
Just coming into this but I see this has been merged? Is there anything to be done here? Thanks A
sorry for causing confusion. That PR became just a bump of LLVM and the bit that was merged is just the small bootstrap-tools bump the work depends on. So this has no impact on this issue. I continue to work on both getting LLVM updated and the Apple SDK. You can keep an eye on or the Discourse thread for updates.

This issue has been mentioned on NixOS Discourse. There might be relevant details there:
I marked this as stale due to inactivity. &rarr;
Package ‘python3.9-watchdog-2.1.6’ in /nix/store/16znkxs25xghynrdrrcf3asczxh3hdm3-nixpkgs-22.05pre346850./nixpkgs/pkgs/development/python- is marked as broken, refusing to evaluate.
Hi all, is there a recommended workaround for this?
I used to create a Python virtualenv with my , then just install directly with inside that virtualenv: I mainly use this for , and it WAS working correctly. I don't have a mac currently, so can't say if it still works, but you can give it a try.
