You can't rebuild Ubuntu (or debian) all at once. You only (re)build packages you care about. I suggest you get on ubuntu arm IRC or mailing lists for more details. cheers nicolas ___ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto

Is there a way to replicate the build infrastructure locally in my environment? I have a quad core i.MX6 platform.

OE/Yocto can help you build a filesystem for your target, that's what it's here for, but it won't generate an Ubuntu image. it is correct that OE can generate .deb (or .rpm or .ipk) packages, but the generated packages won't be compatible on an Ubuntu system (you won't be able to install and satisfy dependencies). Ubuntu is a 'binary' based distribution. All Ubuntu packages are built on a centralized server (Launchpad), natively on 'actual' hardware. Ubuntu packages for ARM are indeed build on ARM build slaves hosted by Canonical. Launchpad offers 'PPA' (personal package archive) where users can upload their 'source package' and expect them to be built on Canonical build infrastructure. This is the mechanism that was by at Linaro to build ARM .deb packages. Note that since this is a binary distribution nobody rebuilds the entire image from scratch, instead packages are built individually whenever there is a change in the package, and the process of making an image (like Ubuntu daily image, or Linaro Ubuntu images) is just to 'assemble' existing binary .deb packages all together. OE/Yocto is a set of 'tools' and recipes to let you create and customize your own distribution. You can create 'rebuild from scratch' distro with OE, or you can even create a 'binary' distribution if you need that. ___ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
