How to build on steamdeck:

Step 0 - Get to development

Disable read-only mode on steamdeck with: sudo steamos-readonly disable

Step 2 - Setup development environment

• Update System

sudo pacman -Syu

• Install VS code

pacman -S code

• Install base-development tools (gcc, g++, make, pkgconf, binutils, patch, fakeroot)

sudo pacman -S base-devel cmake git

• Install Ninja

pacman -S ninja

• Install QML through the online installer

Step 3 - Install all dependencies (updated on: 27/09/2025)

Go through the submodule installations guides to install all dependecies (see the following READMEs). For Windows I used VCPKG for as package manager, for Linux I just the platforms packagemanager. QML was installed through the online installer.

• ExpressUSB-Controller - Establishes communication with a ExpressLRS transmitter

  • BOOST ASIO sudo pacman -S boost

• OpenIPC-QML-Element - Establishes a video stream with a RTL8812AU wifi Receiver

  • FFMPEG sudo pacman -S ffmpeg ffmpeg-libs
  • LibSodium sudo pacman -S libsodium
  • LibUSB sudo pacman -S libusb

• SDL-RC-Controller - Maps keyboard & controller inputs to channels for use with ExpressUSB

  • SDL2 sudo pacman -S sdl2 sdl2_image sdl2_mixer sdl2_ttf sdl2_net

step 4 - Build and pray for no error

• if you get any, I suggest asking GPT
• if that does not work out, Ask a friend or make a issue!
