Failure To Build: panic: unable to find artifact 'facil.io'

[tekktonic]

After following the instructions in the readme for the build info, attempting to run a zig build fails. I assume I either did something silly or that the documentation in the readme is missing a step, but I'm not sure which it is. The project is a straight-up zig init-exe with the modifications indicated in README.md.

zig version
0.11.0

build.zig.zon:

.{
    .name = "test",
    .version = "0.0.1",

    .dependencies = .{
        // zap v0.2.0
        .zap = .{
            .url = "https://github.com/zigzap/zap/archive/refs/tags/v0.2.0.tar.gz",
            .hash = "1220614483f9638f29c6c1bf07c03e945ea28a1055b82f500d3628f4134dc582b6ed",
        },
    },
}

build.zig

const std = @import("std");

// Although this function looks imperative, note that its job is to
// declaratively construct a build graph that will be executed by an external
// runner.
pub fn build(b: *std.Build) void {
    // Standard target options allows the person running `zig build` to choose
    // what target to build for. Here we do not override the defaults, which
    // means any target is allowed, and the default is native. Other options
    // for restricting supported target set are available.
    const target = b.standardTargetOptions(.{});

    // Standard optimization options allow the person running `zig build` to select
    // between Debug, ReleaseSafe, ReleaseFast, and ReleaseSmall. Here we do not
    // set a preferred release mode, allowing the user to decide how to optimize.
    const optimize = b.standardOptimizeOption(.{});

    const exe = b.addExecutable(.{
        .name = "test",
        // In this case the main source file is merely a path, however, in more
        // complicated build scripts, this could be a generated file.
        .root_source_file = .{ .path = "src/main.zig" },
        .target = target,
        .optimize = optimize,
    });
    const zap = b.dependency("zap", .{
        .target = target,
        .optimize = optimize,
    });
    exe.addModule("zap", zap.module("zap"));
    exe.linkLibrary(zap.artifact("facil.io"));
    exe.linkLibC();
    // This declares intent for the executable to be installed into the
    // standard location when the user invokes the "install" step (the default
    // step when running `zig build`).
    b.installArtifact(exe);

    // This *creates* a Run step in the build graph, to be executed when another
    // step is evaluated that depends on it. The next line below will establish
    // such a dependency.
    const run_cmd = b.addRunArtifact(exe);

    // By making the run step depend on the install step, it will be run from the
    // installation directory rather than directly from within the cache directory.
    // This is not necessary, however, if the application depends on other installed
    // files, this ensures they will be present and in the expected location.
    run_cmd.step.dependOn(b.getInstallStep());

    // This allows the user to pass arguments to the application in the build
    // command itself, like this: `zig build run -- arg1 arg2 etc`
    if (b.args) |args| {
        run_cmd.addArgs(args);
    }

    // This creates a build step. It will be visible in the `zig build --help` menu,
    // and can be selected like this: `zig build run`
    // This will evaluate the `run` step rather than the default, which is "install".
    const run_step = b.step("run", "Run the app");
    run_step.dependOn(&run_cmd.step);

    // Creates a step for unit testing. This only builds the test executable
    // but does not run it.
    const unit_tests = b.addTest(.{
        .root_source_file = .{ .path = "src/main.zig" },
        .target = target,
        .optimize = optimize,
    });

    const run_unit_tests = b.addRunArtifact(unit_tests);

    // Similar to creating the run step earlier, this exposes a `test` step to
    // the `zig build --help` menu, providing a way for the user to request
    // running the unit tests.
    const test_step = b.step("test", "Run unit tests");
    test_step.dependOn(&run_unit_tests.step);
}

idk if it's related but for some reason my latest push hadn't gone through. zap doesn't depend on an external facil.io anymore. i've pushed and will try a simple example myself now

I could reproduce. Was indeed a problem with the new way we depend on facil.io (vendored-in). It is fixed. Please try with 0.2.1. README has been updated. (Or see the release notes / discord announce channel for new hash.)
