MacOS Big Sur: libcarbon linker error on shadow-cljs server startup

[solussd]

Workaround: add :fs-watch {:hawk false} to shadow-cljs.edn config.

Error upon running npx shadow-cljs server:

Related to:

• File watching fails on MacOS Big Sur beta bhauman/figwheel-main#253
• Update jna dependency to restore native file watching on Macs gjoseph/BarbaryWatchService#14

There doesn't yet appear to be a corresponding PR in hawk itself, although bhauman said they'll get it into hawk when it's ready.

Others have reported that it seems work fine with macOS release? See #767

I'm not sure if this is very related, but I came across a similar issue (does not mention Carbon) running npx shadow-cljs server in this fulcro template.

shadow-cljs - config: /Users/brandon/development/fulcro-template/shadow-cljs.edn

Adding :fs-watch {:hawk false} to the shadow-cljs config fixed it, but is that supposed to be necessary?

Big Sur 11.5.2
shadow-cljs:

=== Version
jar:            2.15.8
cli:            2.15.8
deps:           1.3.2
config-version: 2.15.8

This machine has the M1 chip, though I don't know if that matters in this case.

[thheller]

:fs-watch {:hawk false} is not an option anymore so it will do nothing, unless you are still on an older version? Which thheller/shadow-cljs version do you have in your deps.edn?

[bpringe]

I see. In deps.edn the version is 2.11.8, so maybe that's why that option worked for me.
