Thread 'wasm' panicked — missing requires CPU features: BMI2 | AVX2 | AVX512DQ | AVX512VL | AVX512F

Zellij fail to start on one of our server. It seems that its processor doesn’t have the required hardware feature. It’s not blocking for me (I have access to another server where zellij does work which is connected to the same environment), so I only send that bug report in case it may interest you.

Basic information

zellij --version: zellij 0.34.4 stty size: 65 291 uname -av: Linux cnode71.silvaco.com 3.10.0-1160.31.1.el7.x86_64 #1 SMP Thu Jun 10 13:32:12 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux (it’s a rhel7 machine)

List of programs you interact with: tcsh 6.18.01 (Astron) 2012-02-14 (x86_64-unknown-linux) options wide,nls,dl,al,kan,sm,rh,color,filec connected from an macOS Catalina (10.15.7), using OpenSSH_8.1p1, LibreSSL 2.7.3

I have the same issue on our server.

[VincentBerthier]

Pretty much the same thing, though in my case zellij launches, but without the plugins (tab-bar and status-bar).

Here's the logs if it can help: zellij.log

[nothingnesses]

In my case, removing ~/.cache fixed the issue, I suspect because I made a change to the VM running zellij which removed those CPU instructions, and removing the cache forced the plugins to be rebuilt without relying on them.
