I submitted a similar error report for building with go a few days ago. Cannot find my submission. Using same go version, 64 bit Bookworm, same build same go on Pi4 Bullseye is fine.

[glowinthedark]

A possible workaround is to cross-compile it on some other box with a working golang env (e.g. linux x64, mac x64/arm64, etc) with:

git clone https://github.com/dundee/gdu.git
cd gdu/cmd/gdu
GOOS=linux GOARCH=arm64 go build -o gdu main.go

This will produce the gdu executable for aarch64 that will run n a pi5, etc.

Glowinthedark,

The problem I discovered last night is that I installed the arm6l version on both the Pi4 and Pi5. The Pi5 with Bookworm is 64 bit and requires the arm64 go install. Tested this morning and it builds fine now. I replied to my post this morning.

Thanks for taking the time and trouble to help.

Cheers. SK!

@skutoroff: confirming — the root cause is installing an armv6l version of golang on an arm64 OS. Removing the go env and reinstalling the arm64 flavour from https://go.dev/dl/ solves the issue.
