"error: unexpected" on Ubuntu 18.04

[CaioLC]

Zig Version

0.14.0

Steps to Reproduce and Observed Behavior

I'm running zig on a relatively old machine with ZorinOS 15 (builds on top of Ubuntu 18.04).

Steps to reproduce:
installed version 0.14 and added to path
mkdir hello
cd hello
zig init
zig build
// outputs "error: unexpected"

The error seems related to the build command. If I run zig run .src/main.zig it compiles and run the default main.zig file.

I switched back to version 0.13.0 and it worked fine.

Expected Behavior

zig build should build the template project.

If possible, it would be helpful if you could try building Zig from source to get a Debug version of the compiler. That would give a stack trace so we'd know what the unexpected errno is and where it's coming from.

If not, any relevant information about your setup might be useful (filesystem, linux kernel version, glibc version, etc). Possibly related: #20423
