Hi Ross I must admit, that I've only experimented with this in my own embedded projects, so there's not really much evidence that this "just works". The issue I ran into, which was fixed by this, was that pkg-config just didn't build on modern compilers as I wrote initially. I'm willing to put in some time to making this work though, but I will probably need some guidance in respect to what level of similarity we need and how to verify it properly. Currently I just know that all of the recipes I've built produce a binary, but I haven't given much thought to binary equivalence. I'll start by kicking off a world build, and seeing where that goes. /Frede
