Signalbot
This project realizes a signal community bot known from other social plattforms like Twitch, Discord & Mumble. It is based on the simple request to automatically remind a groupchat of upcoming birthdays and events.
Installation
This chapter covers the whole installation of the signalbot while using a Raspberry Pi 4 with RaspberryOS already installed. Additionally you'll need a phonenumber that is not linked to an existing signal account. If you just want to use the bot via Signal scroll down to Features .
Installation preparation
This section describes how to install signal-cli on a Raspberry Pi 4. Note that earlier hardware versions are not supported due to the built-in processor generation.
- Installation JRE:
$ sudo apt-get install default-jre - Installation Gradle:
$ sudo apt-get install gradle - When installing Rust on a Raspberry Pi, it is recommended to install rustup - The Rust Language installer by snapcraft
- Installation of the Snap Store:
$ sudo apt install snapd - Restart the Pi:
$ sudo reboot - Installation of core snap:
$ sudo snap install core - Installation of rustup:
$ sudo snap install rustup --classic
- Installation of the Snap Store:
- Installation of the protocol buffer compiler:
$ sudo apt install protobuf-compiler
Compilation of the signal-cli libraries
The signal-cli equires the libraries Libsignal-client and Libzkgroup. They will be downloaded from GitHub and then compiled.
- Installation of the Libsignal-client library
- Switch to the java directory:
$ cd java - Comment out the compilation of the Android Lib with
# $ sed -i "s/, ':android'//" settings.gradle-
$ ./build_jni.sh desktop
The compiled library is then located in the directory libsignal-client under target/release/libsignal_jni.so.
- Switch to the java directory:
- Installation of the Libzkgroup library
-
$ make libzkgroupYou can optionally compile with four processor cores using the-j4parameter.
