[Resolved] Omega2+ Cross Compilation on Ubuntu 17.04 LEDE Build failing



  • Hi,
    Im following the Cross Compilation guide for the Omega 2 https://docs.onion.io/omega2-docs/cross-compiling.html and when running the command:

    make 
    

    of the LEDE source, it is failing with the following error on my Ubuntu 17.04 Droplet server.

    Any advise on what the issue could be?



  • In case anyone stumbled upon this issue or something related to this.

    Since I do not have a linux machine, I decided to spin up a cheap 1cpu, 512MB ram, $5 digital ocean droplet to setup my toolchain and compile some code for the onion. The above issue occurred on a fresh ubuntu 16 and ubuntu 17 droplet. A friend did some googling and pointed out that these type of issues could be memory related and he was spot on.

    After setting up 2GB swap space using this guide: Adding Space on Ubuntu the compile has completed successfully on both Ubuntu 16 and 17.

    Hope this helps someone experiencing this frustration.

    Cheers.
