Source Code

Download the latest source code from DefiCh/app and extract them to your /home/user/ directory (eg. /home/pi/):

Build app-3.x.x

Install dependencies for sandbox

AppImages based on Electron require the kernel to be configured in a certain way to allow for its sandboxing to work as intended. Many distributions come with this configured out of the box, but not Raspberry OS. Specially the new Raspberry OS Bullseye does not allow to run appimages. This issue is fixed by installing:

sudo apt-get install flatpak

Install dependencies for node

Once installed, the node and npm commands are available for use and will remain updated for the channel you selected:

curl -fsSL https://deb.nodesource.com/setup_19.x | sudo -E bash -
sudo apt-get update
sudo apt-get install -y nodejs

Check if dependencies are installed as requested by nodejs installation:

sudo apt-get install gcc g++ make

You need node v19, and npm v8 for this project, it's required to set up the npm workspaces. So you have to upgrade npm:

sudo npm install -g npm@latest

Setup the required binary

Copy respective replace the files into home/pi/app-3.x.x (replace "x" by actual version):

pre-build-armv7l.sh
pre-build-arm64.sh
package.json

NOTE: The files pre-build-armv7l.sh and pre-build-arm64.sh will download my Defi Node from my repositories and copy it into your app directory. If you use your own build Defi Node you have to replace the download link in the files with your directory.

To build the app using arm platform

Change to your app directory cd /home/pi/app-3.x.x and initiate the sricpt to perform by:

npm run init --legacy-peer-deps

NOTE: Warnings occures! The Raspberry OS 32-Bit works, the 64-Bit version too - when they run through... To be honest, the longer the more problems I have to compile the Defi-Wallet. Outdated node modules make me despair in the 64-bit version. If npm run init doesn't work you can use npm run init --legacy-peer-deps or npm run init --force. Anyway I recommend npm cache clean --force for every new run...

Build app

And finally:

• for 32-Bit OS run npm run build:armv7l
• for 64-Bit OS run npm run build:arm64
