It seems this configuration is sometimes a bit tricky. At home, I wanted to configure a Raspberry Pi with a OpenVPN docker container, a DNS server (unbound) and other services.[...]
This error came up when trying to build Qt 6.3 for the Raspberry Pi: This means that the build must also link to libsystemd, so a quick fix is:[...]
Sometimes I need to have specific versions of Qt to build apps and run CI tasks. In this article I introduced what I used for this purpose: a multi-arch docker[...]
The old days of OpenMAX and omxplayer are now almost gone. Raspberry Pi has long moved to DRM/KMS and V4L2. Using omxplayer from Qt had the great benefit of reducing[...]
Raspberry OS based on Debian bullseye was recently published. The compiler provided with this new version was updated to 10.2.1. As usual, I need to cross build many large projects[...]
Getting hardware acceleration into Qt eglfs is tricky. Doing so on a Raspberry Pi is, unfortunately, still tricky after many years. Qt claimed to have reimplemented the Qt Multimedia module[...]
Polr is a cute self-hosted service that allows you to shorten URLs with a practical web interface. Unfortunately, as usual, I couldn’t find a good docker image for arm devices.[...]
It has been some time since Qt 6 was released. Now that Qt 6.2 is almost out, I guess it is time to have a look at how Qt 6[...]
I recently started to add many useful open source services to my Raspberry Pi, like Jenkins, GitLab etc… I wrote some articles about running some services on a arm64 device[...]
I really like this excellent piece of software. I found some docker images for it for the arm64 architecture, but they seemed not to be very up to date, so[...]
I recently had to rebuild the Ubuntu kernel for the Raspberry Pi pretty often to apply some patches. Building on the Pi is simple, but takes A LOT of hours[...]
NOTE: this project now also includes Android builds of Qt. Refer to updated articles to know more. Intro It happens from time to time that I would benefit from having[...]
I recently started to use MediaWiki as a way to store personal information, notes, links etc… It is comfortable to have all that info with me, properly structured, immediately editable[...]
Blog It’s been many years now since I started to use a Pi as a version control server. I recently even started to use it more heavily for my development,[...]
Raspbian Buster is out. It seems it updated gcc from version 6.3.0 (used for Stretch) to gcc version 8.3.0. This is not always needed, but I had a lot of[...]
Raspberry has a huge community that creates a considerable amount of material in a large number of projects. A relevant support for Yocto cannot therefore be missing for it. Months[...]
This was a good test for my cross toolchain with gcc 6.3.0 I uploaded some days ago: the new Qt 5.10.0 built with -march=armv8-a -mtune=cortex-a53 -mfpu=crypto-neon-fp-armv8 -mfloat-abi=hard, including POT for[...]
Raspbian Stretch is out for Raspberry Pi. I needed a cross toolchain with the same exact version used to build the system so I built my own. As I had[...]
At the moment I still don’t want to test custom firmwares or 64 bit arch builds, but I started to test a couple of new features: a new compiler from[...]
A few months back I decided to try to implement hardware decoding in WebKit. Unfortunately this task is always pretty long and complex for many reasons. I found the time[...]
