Arm64 official builds broken #9923

Closed mmitche closed 4 years ago

mmitche commented 6 years ago

@janvorli @sdmaclea The arm64 builds appear to still be broken, though the errors is different than before. Can you take a look?

The failing command is something like this /usr/bin/clang-3.9 -Wall -std=c11 -target aarch64-linux-gnu -B /crossrootfs/arm64/usr/lib/gcc/aarch64-linux-gnu -L/crossrootfs/arm64/lib/aarch64-linux-gnu --sysroot=/crossrootfs/arm64 hw.c -o hw.arm64 -rdynamic

I get similar errors when the rootfs is not present at /crossrootfs/arm64

I'll try to figure out how to load the docker tag and see if I can see what is going on

The rootfs build failed.

Looks like "arm" and "arm64" rootfs images are failed to build in every log.

I can see many failures to mount binfmt_misc filesystem in the log. I wonder if that's related to the issue.

18:03:27 mount: permission denied

@sdmaclea Do you know what dotnet-buildtools-prereqs-docker sha generated a correct image? We may be able to rerun and diff the logs.

sdmaclea commented 6 years ago

The current arm pipeline build is using ubuntu-14.04-cross-0cd4667-20170319080304. That should correspond to a sha of 0cd4667. Unfortunately it is 10 months before the initial commit in the public repository.

The earliest logs are from build 5 which failed on both "arm" and "arm64" on Unbuntu 16.04. I'll take a look at the 14.04 builds.

The earliest 14.04 log has the same issue. https://ci.dot.net/job/dotnet_dotnet-buildtools-prereqs-docker/view/Official%20Builds/job/master/job/ubuntu_14_prtest/5/console

Looks like @janvorli is right those binfmt errors are problematic.

There was also hint elsewhere that configuring the host to mount binfmt may also fix the issue

@RussKeldorph changing the milestone to release/2.1 because this will affect arm build as well.
