Building WebView via Prebuilt Qt

Overview

This method only works on the following devices:

• Raspberry Pi 4 (64-bit)
• Raspberry Pi 5 (64-bit)

Prerequisites

Note

Cross-compilation is not yet supported. You need to have the following installed and set up on your Raspberry Pi 4 or Raspberry Pi 5 device:

• Docker (arm64)
• Code editor of your choice (e.g., Visual Studio Code, Neovim, etc.)

Building the WebView

Clone the repository:

$ git clone https://github.com/Screenly/Anthias.git

Navigate to the webview directory:

$ cd /path/to/Anthias/webview

Initialize environment variables:

$ export GIT_HASH=$(git rev-parse --short HEAD)

$ export COMPOSE_PROFILES=pi5 # For Raspberry Pi 5
$ export COMPOSE_PROFILES=pi4-64 # For Raspberry Pi 4

Start the builder container with the following command:

$ docker compose up -d --build

You should now be able to invoke a run executing either of the following commands:

$ docker compose exec builder-pi5 /webview/build_webview.sh
# or
$ docker compose exec builder-pi4-64 /webview/build_webview.sh

$ docker compose exec builder-pi5 bash
# or
$ docker compose exec builder-pi4-64 bash

# Once you're in the container, run the following command:
$ /scripts/build_webview.sh

The resulting files will be placed in ~/tmp/<platform>/build/release, where <platform> is either pi5 or pi4-64.

When you're done, you can stop and remove the container with the following commands:

$ docker compose down
