Overall I had to do this with these packages and patches:

• libselinux: https://www.spinics.net/lists/selinux/msg26619.html
• libgpg-error: https://dev.gnupg.org/rE7865041c77f4f7005282f10f9b6666b19072fbdf
• gnupg: https://bugzilla.suse.com/show_bug.cgi?id=1121223

I’ll provide all these patches and recipes from my own git server on my website, link at the end, this articles purely educational. What you can do is actually just download this, run the first bits with hopefully no debugging. Whoops… maybe I should’ve mentioned that at the start? But then we never learn :). So he’s our resultant success message:

Keep in mind we haven’t built an image, we’ve built a recipe which includes DEPENDS and RDEPENDS for a large number of recipes which we may or may not eventually need in our build. Basically, we’ve built a package feed for our build or deployed systems. Let’s index that feed as it’s required for later:

bitbake package-index

Now, you can actually point a NI Linux RT (x64) system to that directory (network shared in some fashion permitting) from opkg.conf and after running opkg update, actually install new packages you just built!
