I've generated a list of missing files by comparing the image built from the above config to the official onion omega image.

List of missing files (there may be other modified files too):

Here is the config differences I used as generated by ./scripts/diffconfig.sh

This guide covers a lot of general OpenWRT build process not covered by the onion wiki and I've found it helpful. In particular, setting the target and then running make defconfig was helpful to me.

For a list of installed packages, I extracted the list from the official build from /usr/lib/opkg/status on the Omega (It can also be extracted by using binwalk -e with unsquashfs on a local machine)

Then finding the appropriate packages in make menuconfig by searching for PACKAGE_packagename eg: PACKAGE_oupgrade.

I could not build the arduino-dock (the repository isnt public yet?) or the onion-repo-keys (I need to generate my own keys). I required additional [host] packages to build some of the other packages (including something perl xml)

With make meunconfig, using <*> installs the package into the image. Using <M> builds the package but does not install it into the image.

I still seem to be missing some files. A lot of them are generated from /rom/etc/uci-defaults (just /etc/uci-defaults in the image before first run if inspecting using binwalk), but some such as /etc/uci-defaults/14_banner are not (this file may not be provided by a package yet)

Thank you for your response.

I understand what the toolchain is and what it is for.

I'm saying that the versions of feeds.conf supplied in different downloads of the toolchains are different. The wiki suggests to use the latest git version. The toolchain on the main page uses Barrier Breaker. The version posted in the post mentioned above uses Chaos Calmer. I want to know which git branches are used for the official stable builds, as this appears not to be documented anywhere, and I would like to build my own image.

When following the latest git version documented in the wiki, it builds a different toolchain environment than is used in the stable releases, so the binaries link against the wrong library type and version which means the packages will not run on the stable onion omega builds. This is why I would like to see the exact .config generated with make menuconfig that is used with the stable builds.

@Boken-Lin
I would really like a toolchain supplied for each released version (or at least, instructions for generating one myself that matches the released version), so I can build a version from source using the instructions in the wiki. Is this available somewhere?

I think this requires a feeds.conf.default and the .config generated with make menuconfig. I'm not sure if these are the only things required, as the wiki instructions does not put the https://github.com/OnionIoT/OpenWRT-Packages into the factory image. How are these packages included for the versions supplied at http://repo.onion.io/omega/images/ ? Is there anything else required to build an image the same from source?

For the stable version omega-v0.0.5-b251.bin from http://repo.onion.io/omega/images/ :

I couldn't use the wiki instructions as it built an incompatible toolchain and the binaries wouldn't run.

I had to use the toolchain quoted here: https://community.onion.io/topic/9/how-to-install-gcc/51

It has a newer version of feeds.conf.default than the one linked from https://onion.io/downloads
