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:

$ curl -LO https://gist.github.com/hellium6/98f4512a26b4dd0b00c975f44e4dc965/raw/541534efbecf9d29aca458ab5622116655596960/2000apply.diff
$ git apply 2000apply.diff
$ zig build -Doptimize=ReleaseSafe
$ zig-out/bin/zls --version
0.13.0
$ uname -mrs
NetBSD 10.0 amd64

devel/zls: Add patches to make zls unbroken for zig 0.13.0
