Spider Lily Build System Status#

Last Updated: October 28, 2025 (11:45 PM)
Build Platforms: Windows ✅ | Mac ✅ | iOS ⚠️

📊 Executive Summary#

We now have two fully operational build environments for Spider Lily:

  • Windows builds running on GCP (automated, cloud-based)
  • Mac builds running on local M4 Mac Mini (zero cost, high performance)

Both environments can compile, cook, and package Spider Lily from Perforce. Mac builds produce a working 1GB .app bundle that launches successfully. iOS builds are 95% complete but blocked by Apple's code signing requirements.

🎯 Current Status#

✅ Windows Builder (Production)#

Platform: Local Windows PC (via Docker host)
Location: host.docker.internal (accessible from dev container)
Status: Fully operational

  • ✅ UE5.6 installed with Perforce workspace at C:\Perforce\SpiderLily\SL_main
  • ✅ Connected to Helix Core (ssl:falsework.helixcore.io:1666)
  • ✅ Spider Lily built and deployed for Windows
  • ✅ Fully automated build pipeline (remote-update-and-build.fish)
  • ✅ Builds automatically uploaded to builds.false.work
  • ✅ Zero cloud costs (local machine)

Build Configuration:

  • Start Map: L_VerticalSlice_MainMenu (main menu level)
  • Excluded Assets: /Game/Developers, /Game/LIB/Characters/Player/Animations/OLD
  • Deleted Assets: M_PP_Sky.uasset (shader deadlock prevention)
  • Build Flags: -buildmachine -forcelogflush -MaxParallelShaderCompileJobs=6
  • PowerShell Script: build-false-work.ps1 (automated, no prompts)

SSH Access:

  • From dev container: Use win alias (shortcut for ssh me@host.docker.internal)
  • Example: win "dir C:\Perforce"

✅ Mac Builder (Production)#

Platform: M4 Mac Mini (10 cores, 16GB RAM, 460GB disk)
Location: Local (SSH from dev container)
Status: Fully operational

Build Infrastructure:

  • ✅ SSH access configured (host.docker.internal)
  • ✅ UE5.6 installed at /Users/Shared/Epic Games/UE_5.6
  • ✅ Perforce workspace synced (~/Perforce/spiderlily_build_workspace_macmini/SL_main/)
  • ✅ FMOD Mac binaries installed
  • ✅ .NET 8 SDK installed (required for UnrealBuildTool)
  • ✅ Xcode 26.0.1 with SDK patched for UE5.6 compatibility

Build Scripts Created:

  • package-spiderlily-mac.sh - Full packaging workflow with auto-fix
  • build-spiderlily-editor.sh - Editor-only builds
  • patch-ue5-xcode26.sh - SDK version compatibility fix
  • copy-fmod-mac-files.sh - FMOD binary installation
  • ssh-mac.fish - Quick SSH helper

Recent Achievements:

  • ✅ Successful Mac build! (~1GB .app bundle)
  • ✅ .app launches and runs correctly
  • ✅ Build time: ~30 seconds (after fixes)
  • ✅ Automated FMOD header bug detection & fix
  • ✅ Zero cloud costs (local Mac)

Known Issues Fixed:

  1. Xcode 26 SDK rejection - Patched Apple_SDK.json to accept SDK 26.0.1
  2. FMOD header generation bug - UnrealHeaderTool generates allbackHandler.h instead of FMODCallbackHandler.h
    • Auto-detected and fixed via sed replacement in build scripts
    • Retry logic implemented for clean builds
  3. Missing UE content - Archive step was copying wrong .app bundle
    • Fixed by manually copying from StagedBuilds to Packaged directory

⚠️ iOS Builder (95% Complete)#

Platform: Same M4 Mac Mini
Status: Blocked by code signing

What's Done:

  • ✅ iOS SDK 26.0 available
  • ✅ package-spiderlily-ios.sh script created (supports simulator & device)
  • ✅ FMOD iOS binaries present
  • ✅ Team ID configured (F7G74Z35B8)
  • ✅ Bundle ID set (com.falsework.SpiderLily)
  • ✅ Automatic signing enabled in config

What's Blocking:

  • ⚠️ Xcode requires GUI interaction for initial code signing setup
  • ⚠️ Even simulator builds need development team approval in modern Xcode

To Unblock:

  1. Open Xcode workspace: ~/Perforce/.../Intermediate/ProjectFiles/SpiderLily_IOS_SpiderLily.xcworkspace
  2. Select SpiderLily target → Signing & Capabilities
  3. Check "Automatically manage signing"
  4. Select Personal Team from dropdown
  5. Build once in Xcode (Cmd+B)
  6. Then automated script will work

🚀 Next Steps#

Immediate (This Week)#

  1. ⚠️ Unblock iOS builds - Complete Xcode signing setup (15 min)
  2. 🔄 Automate Mac deployment - Script to upload .app to false.work
  3. 📝 P4 CLI setup - Add Perforce command-line tools to PATH

Short Term (Next Sprint)#

  1. GitHub Actions for Mac - Set up self-hosted runner on Mac Mini
  2. Automated build triggers - P4 commit → auto-build → deploy
  3. Build notifications - Discord/email alerts on success/failure
  4. Version tagging - Integrate P4 changelist numbers into builds

Long Term#

  1. Distribution pipeline - Automatic upload to Steam/Epic/App Store
  2. Crash reporting - Integrate Sentry or similar
  3. A/B testing builds - Deploy multiple versions simultaneously
  4. Build metrics - Track build times, success rates, disk usage

💰 Cost Analysis#

Current Costs#

Platform Setup Cost Per Build Monthly (10 builds) Notes
Windows (Local) $0 $0 $0 Local PC, zero cloud costs
Mac (Local) $0 $0 $0 M4 Mac Mini, zero cloud costs

� Known Issues & Workarounds#

FMOD Header Bug#

Issue: UnrealHeaderTool generates #include "allbackHandler.h" instead of "FMODCallbackHandler.h"
Workaround: Automated sed replacement in build scripts
Impact: Adds ~5 seconds to first build attempt
Status: Permanent workaround in place until Epic fixes UE5.6

Xcode 26 Compatibility#

Issue: UE5.6 rejects macOS SDK 26.0.1 (too new)
Workaround: Patch Apple_SDK.json to accept SDK 26.x
Impact: One-time manual patch
Status: Documented in patch-ue5-xcode26.sh

iOS Code Signing#

Issue: Command-line builds require Xcode GUI setup first
Workaround: Open workspace in Xcode once, then automate
Impact: 15 min one-time setup
Status: Waiting on team action
