The following command installs the VM tools, needed if you are running in a virtual machine, with VMWare or VirtualBox: Sudo apt install openssh-server net-tools -y You will be prompted for your user password, type it into the terminal and then press enter. Sudo apt update & sudo apt full-upgrade -y Run the following command - note: each line is a separate command: ![]() Once installed, open up a terminal by clicking on the bottom left menu icon > System Tools > LXTerminal. Install LUbuntu using the installation menu. ![]() Make a note of how many vCPU's you allocated, it will be needed later. if you have 8 threads (if you have an i7), 4 vCPU’s is a good choice. As many virtual CPU cores as you can spare, but I would recommend no more than half the number as your PCs threads, i.e.Once you have a virtual host installed, such as VirtualBox or VMWare’s player, and the LUbuntu image downloaded, create a new virtual machine with the following settings: If you do not already have a virtual machine host installed, Oracle’s VirtualBox works well and is free, available here: The “Alternate” download image is best, as it has the least extra software that won’t be needed, and saves some space and download time. I would recommend Ubuntu 18.04, or best LUbuntu 18.04, as it is lightweight and flexible. For these reasons it is best to use a VM. Issues can also crop up due to conflicts with software you already have installed. If anything goes wrong with the installation, you can delete the Linux VM, and start again. If you already use Linux, you can install the tools and Qt on your normal machine, but I would recommend against this unless you are sure. You will need a fresh Linux virtual machine for the development. Once you have the image downloaded, and Etcher installed, open Etcher, and open the Raspberry Pi image, and burn it to the SD card.Ĭlick "Flash from file" and select the Raspberry Pi Image:Ĭlick "Select target" and choose your SD card:Ĭlick "Flash!" and wait for it to burn to the SD card: You will also need to download Balena Etcher to burn the image to the SD card, available here: I recommend the medium sized image: “Raspberry Pi OS (32-bit) with desktop”. You will need to download the latest Raspberry Pi OS image from the Raspberry Pi website, available here: Linux VM to install Qt and the required software in - LUbuntu 18.04 alternate used here and recommended.Ideally Ethernet network between Pi and and PC, WiFi will do but is slower.A computer with an SD card read or USB SD card reader - any OS will do.Raspberry Pi 3 and suitable 2.1A power supply.Build a Qt example, and deploy and run it on the Pi!īefore we start out, there are a few things that you are going to need:.Build Qt from source, and any Qt modules we might need.Create a sysroot folder in the Linux virtual machine, which we will use to synchronize the Qt libraries we will build onto the Pi.Install all software and tools needed in a Linux Virtual Machine (VM).Install Raspberry Pi OS (Buster) onto an SD card for the Raspberry Pi, and get it ready for development.Once we have finished, you will be able to write code with Qt as you normally would, and then when you’re ready to build for the Pi, just select it as a build option and compile for the Pi! ![]() This article will walk you through all the steps needed to cross compile Qt 5 code for the Raspberry Pi 3 using Linux.
