Other Information

Docker wasn't working and I saw this in the journal:

developer-1688 env[755]: /run/torcx/bin/containerd: /run/torcx/bin/containerd: cannot execute binary file

From the console I found this:

core@developer-1688 ~ $ uname -m
aarch64
core@developer-1688 ~ $ head /run/torcx/bin/containerd | od -S 4
0001250 /lib64/ld-linux-x86-64.so.2
core@developer-1688 ~ $ rm -rf /tmp/t-test; mkdir -p /tmp/t-test && tar -C /tmp/t-test -xf /usr/share/torcx/store/docker\:18.02.torcx.tgz && head /tmp/t-test/bin/containerd | od -S 4
0001250 /lib64/ld-linux-x86-64.so.2

So it seems amd64 torcx packages are getting used somehow. But it does seem the SDK builds arm64 torcx packages. From the SDK:

$ rm -rf /tmp/t1; mkdir -p /tmp/t1 && tar -C /tmp/t1 -xf ~/trunk/src/build/torcx/pkgs/arm64-usr/docker/554b6946fddbe87f7a1620dbcaf4e5c735db0ba37dfc5e4f62f61d06904c4d56156bdf19ec406a365020858e229e5eef0acdd5aac5ae6c9ebafccfad52343822/docker\:1.12.torcx.tgz && head /tmp/t1/bin/containerd | od -S 4 | egrep 'ld-linux'
0001160 /lib/ld-linux-aarch64.so.1

I'll look into how the torcx packages get into the store and why the wrong arch packages are getting used. Any pointers would be appreciated.

The files are copied into the image here.

It looks like a few other bits of code near there use FLAGS_board, not BOARD; want to check if that's the issue?

It looks like containerd cross-compilation broke with 1.0.1 (Docker 18.02). I can look into it tomorrow unless you want to handle it.

@dm0- I want to look into how torcx works, so I'll try to fix it.

Okay, but note that the problem is not related to torcx. It's still broken if you run emerge-arm64-usr containerd.
