mix compile fails under macOS

[NickNeck]

Hello, I try to make a customized nerves system with the kiosk_system_rpi3 as a starting point, under macOS. For now, I have copied the repo and removed the artifact_sites entry in mix.exs. After that, I have tried mix deps.get && mix compile. After nearly three hours of happy compiling, I get an error.

build.log:

This looks like its related to the version of erlang that is being compiled, but, I have seen this system fail to build for strange reasons when docker does not have enough resources allocated to it. On linux, this requires more than 8gb of ram for compiling. For example, to build this on circle ci, we had to choose the largest resource class which has 16 gb of ram because the resource class with only 8gb would also fail.

Thank you for your response. I have now a successful build. I gave all my resources to Docker (8 CPUs and 16 GB Memory).

There is another little bug when I run mix nerves.artifact.

The bug described above was fixed in nerves >= v0.10.0. If you run mix deps.update nerves you should be able to get past that part 👍 Please open a new issue if you are still having issues. Thanks!
