Can't build because "generator/vulkan/build_integration.zig" tries to call b.graph.cache.obtain() which doesn't exist

I'm trying to set up a little game, but my build.zig fails:

$ zig build

My build.zig:

const std = @import("std");

pub const Frontend = enum {
    client,
    server,
};

pub const LibType = enum {
    static,
    shared,
};

pub fn build(b: *std.Build) void {
    // Options
    const opt_target = b.standardTargetOptions(.{});
    const opt_optimize = b.standardOptimizeOption(.{});
    const opt_frontend = b.option(Frontend, "frontend", "Whether to produce a client or server executbale") orelse Frontend.client;
    const opt_serverLibType = b.option(LibType, "server_lib_type", "Whether to build the server as a static or a shared library") orelse LibType.static;
    
    // Server library
    const thServer_args = .{
        .name = "thorium_server",
        .root_source_file = .{ .path = "src/server/root.zig" },
        .target = opt_target,
        .optimize = opt_optimize,
    };
    const thServer = switch (opt_serverLibType) {
        .static => b.addStaticLibrary(thServer_args),
        .shared => b.addSharedLibrary(thServer_args),
    };

    // Client/server executable
    const thClient = switch (opt_frontend) {
        .client => b.addExecutable(.{
            .name = "thorium_client",
            .root_source_file = .{ .path = "src/client/main.zig" },
            .target = opt_target,
            .optimize = opt_optimize,
        }),
        .server => b.addExecutable(.{
            .name = "thorium_server_cli",
            .root_source_file = .{ .path = "src/server/main.zig" },
            .target = opt_target,
            .optimize = opt_optimize,
        }),
    };
    b.installArtifact(thClient);

    // Dependencies for server (todo)
    // Dependencies for client
    thClient.linkLibrary(thServer);
    if (opt_frontend == Frontend.client) {
        // GLFW dependency
        const glfw_dep = b.dependency("mach_glfw", .{
            .target = opt_target,
            .optimize = opt_optimize,
        });
        thClient.root_module.addImport("mach-glfw", glfw_dep.module("mach-glfw"));
        // Vulkan dependency
        const vulkan_dep = b.dependency("vulkan_zig", .{
            .registry = @as([] const u8, "deps/Vulkan-Headers/registry/vk.xml"),
        });
        thClient.root_module.addImport("vulkan", vulkan_dep.module("vulkan-zig"));
    }
}

Maybe it's because I'm using zig version 0.12.0-dev.2063+804cee3b9 (2024.1.0-mach to be exact) and the API doesn't exist there yet, but I can't upgrade to master because I'm using mach-glfw.

Yes, this was changed here: #118. I suggest to just use vulkan-zig from a commit before here, for now. Alternatively, we can check the compiler version and pick the new or the old code.

This should be fixed with https://machengine.org/about/nominated-zig/#202430-mach

Alright, it works with 2024.3.0-mach. Thanks for the help :)
