Hey guys. I would like to set a Raspberry PI 4 as a Monero offline (cold) wallet. However, the official GUI package for Linux only works on x86. Any ideas how to cross-compile it for raspberry pi 4 architecture (Arm)?

kmaneo[m]: The easiest thing I can point you towards is to avoid using the GUI, and instead use moneroaddress.org

It is a webpage written by moneromooo that you can use a verified copy of to generate a cold wallet. Instructions for use are on the website.

But I don’t want to just generate a cold wallet. I want to be able to sign transactions from a hot wallet with the view keys only. Basically creating a hardware wallet. The transaction would be exported to a text file from the hot wallet, and imported in the cold wallet using a USB key.

For “hot wallet” I mean a “watch-only” wallet connected to the net

The cold wallet would be used to generate the “the key images” to be used by the watch-only wallet to follow transactions (both received and spent)

The process I would like to follow is documented here:

kmaneo[m]: the process you linked uses the cli, not the gui

kmaneo: might be of your interest monero-project/monero-gui #3680

(oh sorry, you were looking for x-compilation, nvm)

Hey, that’s great, thanks!

I will try to build directly on the raspberry pi 4, then. Perhaps there’s no need to cross-compile on my laptop.
