Yocto Beginner - Build Errors When Layers / Recipes Added

[windswept321]

I have been trying to get a build up and running for the past couple of days following the latest official quick-start guide with no success (Debian 8 —> Debian 7 —> Ubuntu LTS…)

I want to have openssh, ntp, iptables, dnsmasq and hostapd added to the build. The meta-amd layer was added in case of there being anything useful for a GX-412TC Crowned Eagle CPU. It doesn’t seem to have any impact at the moment.

My bblayers.conf customisations:

  /home/aaron/poky/meta-amd/common \

  /home/aaron/poky/meta-openembedded/meta-networking \

  /home/aaron/poky/meta-openembedded/meta-python \

  /home/aaron/poky/meta-openembedded/meta-oe \

Each of these was added to the poky directory using git clone “link”. The last two are dependencies for meta-networking.

I have added the following to my local.conf:

CORE_IMAGE_EXTRA_INSTALL += "openssh ntp iptables dnsmasq hostapd”

On running bitbake core-image-minimal I get the below error.

Is there something wrong with how I am doing this?
