I do quite a few OpenEmbedded project builds during the course of a week. This process usually takes 3-5 minutes. That is just enough time to get distracted doing something else and forget about the build until an hour later when you realize — oops, I was supposed to send out a release email once [...]

I recently wrote an article about best practices building Qt applications with OpenEmbedded, and it occured to me that I should write an equivalent article for Gtk+ applications. The same points apply — put your application source in a SCM system, and put the install logic in the application source (read the above article). The [...]

This article describes how to cross compile a Qt application (named qt_tutorial) with OpenEmbedded, and several best practices you should consider. OpenEmbedded currently includes fairly good support for building Qt — both Qt Embedded and Qt X11. OE also includes a number of qt classes that make building Qt applications easy. One of the main [...]

One task that is a often confusing to new OpenEmbedded users is how to capture changes to the source code for a package/recipe. First, lets review the progression in tools use to capture source code changes.
In days of yore, developers often used gnu diff to capture modifications to a source tree. The typical practice was [...]

This article presents a very nice overview of options to disable ssh host key checking. When working with embedded systems where you are constantly reloading the rootfs, it is really annoying to have to edit your ~/.ssh/known_hosts every time you update the rootfs on the target device. The solution is to simply disable host key [...]

From http://www.embedded.com/design/opensource/204300381 :
Host platform
Although everything I will describe can be also done on a Windows host, I recommend using Linux. It’s more convenient, and more tools and utilities are available. And if you rely on a few Windows applications such as Word and Outlook, you can still run them on Linux in emulation using VirtualBox, [...]

In this day and age, most embedded systems include a way for users to easily update software once the device has been deployed. This article discusses the requirements for a field update mechanism along with pointers for how to implement.
Update Mechanism Requirements
Requirements for a field update mechanism might be:
easy for users to perform updates.
little chance [...]

Recently, I had a customer who needed an embedded Linux distribution running on an Advantech PCM-9371 single board computer (SBC). The PCM-9371 contains a low voltage Celeron or Pentium III processor. This article describes why the Openembedded build system was chosen and a few tips for running Openembedded on a x86 system.
The hard way!
There are [...]

At some point, most Linux developers need to master Autotools. For most of us, this is a fairly painful process, but like any good tool, Autotools is extremely useful and well worth learning. For example, if your program is set up correctly using Autotools, it will cross compile with almost zero effort in OpenEmbedded, or [...]
