Again, thanks *so* much for putting this together. I tried to do this once before and didn't have the tenacity to stick with it--it is a surprisingly daunting task. Having a smallest-possible example will, I think, be really helpful to developers who want to learn how to debug bitbake and

I am continuing my work on creating a Hello, World! BitBake project. Because of the excellent help I got before, things have gone reasonably well, but I'm again running into something I don't know how to fix. As before, the entire contents of my very small project appear at the end of this

The T variable points to a directory were Bitbake places temporary files when building a particular package. It is typically set to T = ${WORKDIR}/temp WORKDIR is the directory into which Bitbake unpacks and builds a package. The default bitbake.conf file sets this variable. T is not to be

Tasks must be Python functions. No, they can be shell functions too. Probably worth adding that if you are doing an _append() on a task function, you have to match the original function type. E.g., if you want to append a shell snippet to a python task function, you need to do

[Warning: lengthy post, and probably boring to most.] My Bitbake Hello World is a little more than a basic Hello World. It's idea is to incorporate a layer and use a structure similar to what OE and Yocto are using. You can do it simpler if you want to. I did this a while ago with Bitbake 1.12.0.

*Very* helpful stuff. I have re-created the tree you described, and everything seems to work. In particular, bitbake-layers seems happy. I tried executing it against BitBake 1.12.0 and it succeeded. FYI, it failed against the current BitBake master, which is 1.16.0. I have some additional

Hi Patrick, I think I understand what you are looking for. I created this Bitbake Hello World for a training class. It just uses 'raw' Bitbake and a very basic recipe to build the Nano editor (including download from the project site). You need to have a couple of things in place to make this
