ShowEQ and Raspberry Pi

[Shinigami]

As far as I know if you build it with a Pi 3b or 3b+ it should still work. I havent tried it on a 4 yet.

Cheers. Do you know if CentOS 7.x is ok, or will qt be an issue?

Use raspbian for the OS. I dont think CentOS supports ARM cpus. You might have to get an older version of raspbian for it to work.

CentOS 7 is working fine for me on a Pi 4B 4G.

From my notes from about a year ago or so:

yum groupinstall "Development Tools"
yum install qt-devel libpcap-devel xorg-x11-server-Xorg xorg-x11-xauth xorg-x11-apps

I experience frequent 'freezes' with my setup, though, and I'm not sure what causes it. It doesn't freeze to the point that showeq needs to be restarted, it just stops updating until I zone and then it starts working again. I've tried using strace to see if there's anything obvious I can see but other than hundreds of gettimeofday() calls per second, I don't notice anything. I'm no strace expert, though.

I run in a (Debian) Buster based image on Rock64 (ARM64) also 4GB memory and at times I experience frequent freezes. Sometimes it recovers, sometimes it does not. I suspect it's related to the rate of incoming packets which seq has to process. I haven't had time to dig extensively into the C++ to validate. It's possible we're seeing similar behaviour.

Certainly possible. I play on the TLP's and I notice it happening more and more each expansion release. It started getting bad around Planes of Power and just got progressively worse from there.

I wonder if x86 people are having the same issue or if it's just us ARM folk.

Heh I am currently using CentOS 6.10 on a super slow/old laptop, but if Pis are prone to freezing, that doesn't sound like much of an upgrade. Has anyone tried any of the Windows 10 sticks like https://www.amazon.com/Intel-Compute.../dp/B01ASB0DJ8 etc?

I have no problem with my Pi 3b+. It is rock steady. It has been running without reboot since last November when I moved. It is running raspbian.
