Build failing on NetBSD due to error.NetworkUnreachable

Steps to Reproduce and Observed Behavior

• Run NetBSD 10 and optionally setup pkgin to install from repos
• Install zig (e.g. pkgin in zig. This currently installs 0.13.0)
• Clone 0.13.0 release tag: git clone -b 0.13.0 https://github.com/zigtools/zls && cd zls
• Run the build: zig build -Doptimize=ReleaseSafe

Build is failing on NetBSD for some reason. Tried the build same way on FreeBSD 14.1 amd64 (also on zig 0.13.0, same tag, same internet connection) which completed without errors.

Currently it fails with:

$ zig build -Doptimize=ReleaseSafe

   └─ zig build-exe zls ReleaseSafe native
      └─ run zls_gen (version_data_0.13.0_20100.zig) failure

Expected Behavior

Complete build without errors

The langref.html.in file is no longer downloaded during the build phase since #2000 which resolves this issue.

The http implementation is provided by the Zig standard library which can be tested like this:

const std = @import("std");

pub fn main() !void {
    var general_purpose_allocator: std.heap.GeneralPurposeAllocator(.{}) = .{};
    defer _ = general_purpose_allocator.deinit() == .ok;

    const gpa = general_purpose_allocator.allocator();

    var arena_allocator = std.heap.ArenaAllocator.init(gpa);
    defer arena_allocator.deinit();

    var client: std.http.Client = .{ .allocator = gpa };
    defer client.deinit();
    try client.initDefaultProxies(arena_allocator.allocator());

    var server_header_buffer: [16 * 1024]u8 = undefined;

    var request = try client.open(
        .GET,
        try std.Uri.parse("https://raw.githubusercontent.com/ziglang/zig/0.13.0/doc/langref.html.in"),
        .{ .server_header_buffer = &server_header_buffer },
    );
    defer request.deinit();

    try request.send();
    try request.finish();
    try request.wait();

    std.debug.print("status: {}", .{request.response.status});
}

This should reproduce your issue with Zig 0.13.0. If this still fails with the latest nightly build of Zig, I would suggest to open an issue with Zig.

Thanks. Will have to try that.

In the meanwhile, for 0.13.0 on NetBSD, based on the PR, I prepared a patch that successfully builds:
