Compiling fails on arm(64)

[madnuttah]

Hello and thanks for dnsi.

I am currently facing issues while compiling dnsi for arm(64) in a GitHub workflow.

Workflow run log:

The relevant part of the Dockerfile:

...
RUN set -xe; \
    apk --update --no-cache add \
    ca-certificates \
    tzdata \
    build-base \
    curl \
    binutils \
    cargo && \
    cargo install --locked dnsi
...

I can't tell you if it would fail for armv6/v7 too right now. The i386 and amd64 are compiling without issues.

Thank you.

Apologies for the delay, bit of a hectic week around here.

I’m not sure what’s going wrong. I have updated the dependencies on the main branch which updates syn to a newer version. Can you try building from git and see if that works?

[madnuttah]

Thank you, no apologies please. :) I'll try another build and tell you the outcome.

It seems like everything except arm64 compiles. It took quite long and after searching through the log, I saw this error again and canceled the workflow. I wonder why it hasn't been canceled after the error occured... But, due to the long runtime it seems like the other arm builds were successful.

Thank you.

This looks like a rustc bug, because rustc is exiting with a segfault. So here's some questions that might help diagnose the issue:

• What's your compiler version?
• Is this cross-compiling or compiling on arm64?
• What target triple are you using?
• Does the issue persist when using the nightly compiler?

I tried cross-compiling to aarch64-unknown-linux-gnu but that didn't give any issues on rustc 1.78.

[madnuttah]

Thanks for your questions!

• I'm just installing cargo, the rust version is rust (1.78.0-r0). The installations run without issues
• Compiling fails with the error messages mentioned above on arm64 via GitHub workflow calling cargo install --locked dnsi
• The target platforms: linux/386,linux/arm/v6,linux/arm/v7,linux/arm64,linux/amd64
• Not tried it yet, how would I do that?

As all this rust stuff is new to me, I hope I've answered your questions properly.
