I've followed the instructions at https://github.com/OnionIoT/source more times than I can count, I've tried Ubuntu 16.04 and 18.04, setting a clean VM up to build the OS natively, and it fails. Updating loads of things will get the build to continue further, but it never finishes.

I then tried doing the same on Fedora 29, also a clean VM, compilation fails here too (no surprises there).

Lastly I tried compiling using the docker image, on both versions of Ubuntu and on Fedora, and the builds fail.

I'm at my wits end, the docker image should be set up to just build whatever I want, as that is the whole point of using docker. So my question, has anyone had success using the latest docker image on either Ubuntu or Fedora as a fresh VM?

Its getting really demotivating having to start a build an then leave it for 4 or 5 hours only to come back to a failure.

In terms of the VM setup, it is set up with 2 CPU's (I've built using -j1 and -j2), 8GB of RAM and 100GB of storage.

Any pointers are welcome, or if someone has a dockerfile that I can use, even better, as I cant seem to find the Onion dockerfile online.

I've created a fresh container from it and am currently running a make.
Have you tried that?

i.e. Don't update feeds, don't git pull etc.
Just:

1. Install docker
2. docker pull onion/omega2-source
3. docker run -it onion/omega2-source /bin/bash
4. make

I realise that this isn't where you want to be, I just want to confirm that a make can be completed successfully. Here's the result of mine after doing the 4 steps listed above.

I had a similar issue building on Ubuntu 18, my research found there are some issues reported to the maintainers relating to this error, as I recall there is a beta patch circulating.

I just installed Ubuntu 17.10 instead and this resolved the issue.

Thanks for the help ladies and gents

• Ubuntu 18.10
• Ubuntu 18.04
• Kubuntu 18.10
• Kubuntu 18.04

with docker and native compile.
I tried using both clean Desktop installations (with SSD 120GB) and virtual machines using VirtualBox with no success.

Finally I managed to build the toolchain successfully on Windows 10 x64 using the "Docker for Windows"

As @cas mentioned above:
There's only 4 steps:

1. Install docker
2. docker pull onion/omega2-source
3. docker run -it onion/omega2-source /bin/bash
4. make

It took about 5 hours.

I was able to build the image, I think with the docker container on OS X after disabling mosquitto or something like that. At least I’m almost certain I could build a full image...
