build.zig issue - reached unreachable code

[senyai]

First time trying to use zig.

zfltk/build.zig

Line 59 in fa777e7

const prefix = comptime std.fs.path.dirname(@src().file) orelse unreachable;

/home/senyai/.cache/zig/p/1220ed324e831cbcfffdade82d578f2c24eac577facb481951a8f6a8e491eb51d1b8/build.zig:59:69: error: reached unreachable code
    const prefix = comptime std.fs.path.dirname(@src().file) orelse unreachable;
                                                                    ^~~~~~~~~~~

I bet the issue is on my side, but I don't know where to look. I replaced unreachable with
@compileError(@src().file ++ " has no directory"); and got "error: build.zig has no directory". So, why do I need to have a dirname?

Hello
It might be a change in zig. The package management there is still evolving.
What version are you on?

I clicked on the first link on the Zig download page. It's 0.14.0-dev.2051+b1361f237. Downgrading to 0.13.0 solved this issue.
