Hi folks, I am trying to confirm that I will be able to use zflecs and possibly other zig-gamedev libs in my project.
It seems I am able to compile it successfully for the native platforms, but getting an error building it for the web.
My steps: Addzflecs to zon file:zig fetch --save=zflecs git+https://github.com/zig-gamedev/zflecs.git Add to build config.
2.1 Native const exe_mod = b.createModule(.{ .root_source_file = b.path("src/main.zig"), .target = target, .optimize = options.optimize, }); const exe = b.addExecutable(.{ .name = "app", .root_module = exe_mod, }); exe.root_module.addImport("sokol", dep_sokol.module("sokol")); const zflecs = b.dependency("zflecs", .{}); exe.root_module.addImport("zflecs", zflecs.module("root")); exe.linkLibrary(zflecs.artifact("flecs"));
2.2 Web const lib = b.addStaticLibrary(.{ .name = "app", .target = target, .optimize = options.optimize, .root_source_file = b.path("src/main.zig"),});lib.root_module.addImport("sokol", dep_sokol.module("sokol"));const zflecs = b.dependency("zflecs", .{});lib.root_module.addImport("zflecs", zflecs.module("root"));lib.linkLibrary(zflecs.artifact("flecs"));// create a build step which invokes the Emscripten linkerconst emsdk = dep_sokol.builder.dependency("emsdk", .{});const link_step = try sokol.emLinkStep(b, .{ .lib_main = lib, .target = target, .optimize = options.optimize, .emsdk = emsdk, .use_webgl2 = options.backend != .wgpu, .use_webgpu = options.backend == .wgpu, .use_emmalloc = true, .use_filesystem = false, .release_use_closure = options.backend != .wgpu, .shell_file_path = dep_sokol.path("src/sokol/web/shell.html"),});// attach Emscripten linker output to default install stepb.getInstallStep().dependOn(&link_step.step);// ...and a special run step to start the web build output via 'emrun'const run = sokol.emRunStep(b, .{ .name = "app", .emsdk = emsdk });run.step.dependOn(&link_step.step);b.step("run", "Run app").dependOn(&run.step);
Add basic initialization to make sure the linking is ok:
const sokol = @import("sokol");const ecs = @import("zflecs");...pub fn main() void { const world = ecs.init(); defer _ = ecs.fini(world); sapp.run(.{ .init_cb = init, .frame_cb = frame, .cleanup_cb = cleanup, .width = 640, .height = 480, .icon = .{ .sokol_default = true }, .window_title = "clear.zig", .logger = .{ .func = slog.func }, .win32_console_attach = true, });}
Native build works just fine, but getting an error when building for the webzig build -Dtarget=wasm32-emscripten /Users/user/Library/Application Support/Code/User/globalStorage/ziglang.vscode-zig/zig/macos-aarch64-0.14.0/lib/std/debug.zig:870:24: error: no field named 'base_address' in struct 'debug.SelfInfo.Module__struct_7161' module.base_address, ^~~~~~~~~~~~/Users/user/Library/Application Support/Code/User/globalStorage/ziglang.vscode-zig/zig/macos-aarch64-0.14.0/lib/std/debug/SelfInfo.zig:798:27: note: struct declared here .wasi, .emscripten => struct { ^~~~~~error: the following command failed with 1 compilation errors:/Users/user/Library/Application Support/Code/User/globalStorage/ziglang.vscode-zig/zig/macos-aarch64-0.14.0/zig build-lib -ODebug -target wasm32-emscripten -mcpu baseline -I /Users/user/dev/test-app/app-client/.zig-cache/o/ee37129807542079360a73b5258f6822 --dep sokol --dep zflecs -Mroot=/Users/user/dev/test-app/app-client/src/main.zig -I /Users/user/dev/test-app/app-client/.zig-cache/o/b29ba9067f6a406b2885eaf016943dfe -Msokol=/Users/user/.cache/zig/p/sokol-0.1.0-pb1HK1CHLACn6xGB1TLwO5bgMQNY735HMVDwXZ-UHj0C/src/sokol/sokol.zig -Mzflecs=/Users/user/.cache/zig/p/zflecs-0.2.0-dev-1PN3yuhMNQDj3J57z74E3AIGM8bmVg3FhAd6XZKb_A9W/src/zflecs.zig -lc --cache-dir /Users/user/dev/test-app/app-client/.zig-cache --global-cache-dir /Users/user/.cache/zig --name app -static --zig-lib-dir /Users/user/Library/Application Support/Code/User/globalStorage/ziglang.vscode-zig/zig/macos-aarch64-0.14.0/lib/ --listen=- Build Summary: 4/8 steps succeeded; 1 failedinstall transitive failure└─ install generated/ transitive failure ├─ emcc transitive failure │ ├─ zig build-lib app Debug wasm32-emscripten 1 errors │ └─ zig build-lib app Debug wasm32-emscripten (+6 more reused dependencies) └─ emcc (+4 more reused dependencies)error: the following build command failed with exit code 1:/Users/user/dev/test-app/app-client/.zig-cache/o/3b467ad4105444738519ed65b7850836/build /Users/user/Library/Application Support/Code/User/globalStorage/ziglang.vscode-zig/zig/macos-aarch64-0.14.0/zig /Users/user/Library/Application Support/Code/User/globalStorage/ziglang.vscode-zig/zig/macos-aarch64-0.14.0/lib /Users/user/dev/test-app/app-client /Users/user/dev/test-app/app-client/.zig-cache /Users/user/.cache/zig --app 0x4bec60fe -Z0cf29144e1057ec0 -Dtarget=wasm32-emscripten
