Broken on linux-aarch64 since 0.14.1

[johnstairs]

Solution to issue cannot be found in the documentation.

• I checked the documentation.

Issue

Zig versions 0.14.0, 0.14.1, and 0.15.1 do not run on aarch64 systems. Invoking zig fails immediately with

Illegal instruction

or

Segmentation fault

or

zig: error while loading shared libraries: __kernel_gettimeofday: invalid mode for dlopen(): Invalid argument

The specific error seems to vary depending on the system. I've tried a Raspberry Pi and an ARM64 Ubuntu running in a Docker container on ARM64 macos.

Version 0.13.0 does not have this problem.

Thank you, we rely on zig x86 being able to cross-compile to arm64 for that artifact. It is likely to take a bit of time to debug.

[tdejager]

This seems to work for me? I'm on an M1 (Apple Silicon|) osx mac. On Sequioa though.

pixi init zig-test
✔ Created /private/tmp/zig-test/pixi.toml

pixi add zig
✔ Added zig >=0.15.1,<0.16

pixi r zig init
info: created build.zig
info: created build.zig.zon
info: created src/main.zig
info: created src/root.zig

pixi r zig build run
All your codebase are belong to us.
Run `zig build test` to run the tests.

[tdejager]

Just upgraded to Tahoe OSX and still seems to work :)

@MementoRC, @tdejager , the bug is not about macos, but Linux on ARM64. One of my configurations was a Linux docker container running on a mac. But on the mac directly, it works fine.

Thank you for clarifying (I confused myself). We used cross-compilation and some juggling with sysroot/libc. Could you provide the:

• ldd zig
• install it in a custom environment with sysroot 2.28

We are investigating a native build with: #67
Tat may resolve these issues if successful (ETA: a few days)
