OpenVoiceOS - Mycroft Edition

A minimalistic Linux OS bringing the open source voice assistant Mycroft A.I. to embbeded, low-spec headless and/or small (touch)screen devices.

System.

OpenVoiceOS - Full 64 Bit distribution

• Linux kernel 5.10.x (LTS)
• Buildroot 2021.02.x (LTS)
• Mycroft 20.08.x (mycroft-lib pip installable version)
• Raspberry Pi 3|3b|3b+ (Initial development hardware = 3b)
• Raspberry Pi 4 (Current development hardware)

Getting started.

At this moment development is in very early stages and focussed on the Raspberry Pi 3B & 4. As soon as an initial first workable version is created, other hardware might be added.

Getting the code.

First, get the code on your system! The simplest method is via git.

• cd ~/
• git clone --recurse-submodules https://github.com/OpenVoiceOS/OpenVoiceOS.git
• cd OpenVoiceOS

Patching Buildroot.

(ONLY at the first clean checkout/clone) If this is the very first time you are going to build an image, you need to execute the following command once;

• ./scripts/br-patches.sh
  This will patch the Buildroot packages.

Installing System Build Dependencies

The following system packages are required to build the image:

• gcc
• subversion
• qttools5-dev
• qttools5-dev-tools
• python

Building the image.

Building the image(s) can be done by utilizing a proper Makefile;
To see the available commands, just run: 'make help'
As example to build the rpi4 version;

• make clean
• make rpi4_64-gui-config
• make rpi4_64-gui

Now grab a cup of coffee, go for a walk, sleep and repeat as the build process takes up a long time pulling everything from source and cross compiling everything for the device. Especially the qtwebengine package is taking a LONG time.
(At the moment there is an outstanding issue which prevents the build to run completely to the end. The plasma-workspace package will error out, not finding the libGLESv4 properly linked within QT5GUI. When the build stopped bacause of this error, edit the following file;

buildroot/output/host/aarch64-buildroot-linux-gnu/sysroot/usr/lib/cmake/Qt5Gui/Qt5GuiConfigExtras.cmake

at the bottom of the file replace this line;

_qt5gui_find_extra_libs(OPENGL "GLESv2" "" "")

And replace it bit this line;

_qt5gui_find_extra_libs(OPENGL "${CMAKE_SYSROOT}/usr/lib/libGLESv2.so" "" "${CMAKE_SYSROOT}/usr/include/libdrm")

Then you can continue the build process by re-running the "make rpi4_64-gui" command. (DO NOT, run "make clean" and/or "make rpi4_64-gui-config" again, or you will start from scratch again !!!)

When everything goes fine the xz compressed image will be available within the release directory.
