Issues with bitbake for building Angstrom

Question

The issue I'm having is that I'm trying to build an Angstrom image from scratch using bitbake (since Angstrom is now Yocto Compatible) but I've run into an error the moment I run the bitbake systemd-image

Traceback (most recent call last):

I've been at this for a while now, searching on different sites. Originally I tried following the guide at the developer section on the Angstrom site, but once I got some errors (prior to this one I'm putting here), I found Derek Molloy's site http://derekmolloy.ie/building-angstrom-for-beaglebone-from-source/ which solved those errors and gave a little more detail into the process.

Eventually I stumbled onto another forum post which decribed my problem, but unfortunately the answers weren't really clear (for me anyway) http://comments.gmane.org/gmane.linux.distributions.angstrom.devel/7431 . I'm at a loss on what could be wrong, and I'm pretty much new to Yocto project so I'm unsure if there's any steps missing or something that's implicit that I have overlooked, so I would deeply appreciate anyone who could point me on the right direction on this.

As side note, I've been thinking that it could be something having to do with the environment-angstrom-... file that I have, since mine is environment-angstrom-v2013.12 and all the other examples use previous versions, I'm wondering if there's a new step involved when working with this.

Answer 1

为什么要使用系统范围的Bitbake，而不是与Angstrom版本兼容的原因？

Answer 2

Don't use a system-wide bitbake, as the bitbake API can and does change over time. Use the corresponding bitbake for that release of angstrom.

(This is breaking because your bitbake requires getVar to take three arguments but your angstrom layers are only passing two)
