Homebrew package missing MDBX slasher

[bFanek]

Description

I have slasher and slasher-dir arguments configured. After I updated lighthouse to 4.0.1 it now always crashes on startup with this slasher error below. I tried to point slasher-dir to a new empty folder to re-build database from scratch but same error.

Mar 28 16:33:10.298 INFO Opening slasher database                backend: disabled, service: slasher
Mar 28 16:33:10.304 CRIT Failed to start beacon node             reason: Slasher open error: SlasherDatabaseBackendDisabled

Mar 28 16:33:10.304 INFO Shutting down..                         reason: Failure("Failed to start beacon node")

Version

Lighthouse v4.0.1
BLS library: blst
SHA256 hardware acceleration: false
Allocator: system
Specs: mainnet (true), minimal (false), gnosis (false)

Present Behaviour

Beacon node crashes on startup.

Expected Behaviour

Beacon node should run with slasher enabled.

Steps to resolve

It works if I remove --slasher argument but I'd like to keep the slasher running.

Are you running the homebrew package by any chance? We had to disable the slasher on homebrew due to a build error. If you run the binary from our release page or compile yourself you will get a binary with the MDBX slasher backend enabled

Thank you @michaelsproul yes I installed the new version via homebrew on M1 Mac.
I'll compile source code myself and try again today, cheers!

I can confirm the slasher works again when I compile it myself. Thank you!
This issue can be closed.

PS: Isn't there an option for homebrew to compile instead of just install the binaries? would that solve the problem? I know for geth there are 2 repositories: one installs binary (fast) and the other compiles then installs (slower).

cheers
