Technical stuff has been hard to collect this summer. Having a couple weeks off hadn’t helped. So here are some pictures instead.Continue reading
I don’t understand, yet, why this works, but it does. Thanks to this post
I was able to boot my Raspberry Pi using the Pi Imager and the Fedora AARCH64 Raw Image. While this makes me happy, I don’t really understand what these pieces are. So, I want to take a little more look at them.Continue reading
My Day job has me messing around with QT5. We’rer building various RPMs for different RHEL and CentOS versions, and I wanted to get a little more experience on this. Specifically, I wanted to be able to do trial and error on a package that would not pollute our work stream. I wanted it to be something QT based. And I wanted it to be fun.
So I am working on repackaging QGo for Fedora 34 using QT5. Here’s what I am learning.Continue reading
We do RPM things. Some of those RPM things need the /proc file system. Not forever, but for a short while. So we mount /proc, do something, and unmount. Which works fine.
Until we tried to do it in a container.Continue reading
ALSA. Jack. PulseAudio. MIDI. Musescore. Jamulus.
My musical interactions with Linux are not the most complex in the world, but they ain’t trivial. The complexity of the Linux audio landscape has been a stumbling block so far. Pipewire has just gotten me past that.
The title of this article implies that you need to do something other than install Pipewire. So far, this is not true. On my system, at least, it Just works.Continue reading
We are trying to enable the graphics hardware subsystem on the Raspberry Pi 4. This driver lives in mesa. The current Centos mesa.spec file does not enable the V3D Driver we need. Here are the steps I am going through to build the driver and integrate it into the meta-rpm build.Continue reading
I wanted to see how my work had diverged from the standard Raspberry Pi build. Specifically, the image creation stage is failing in my work. I can run the script in the original (upstream) version by doing thing following.Continue reading
config.sub is used to determine, among other things, the architecture of the machine. This is used in the configure script for an autotools based make file.
Older config.sub files don’t know how to handle aarch64, the generic name used for ARM64 servers in the build process. We have a recipe that pulls in code using an older config.sub file and I need to update.
My first approach was to build a patch. This works fine, and it was my fallback, but it is tedious to do for every recipe that needs this update, every time it needs it. It turns out we have a better approach that follows the guide of “don’t repeat yourself.”Continue reading
