Build Presets Guide

CMake presets for development workflow and architecture-specific builds.

🍎 macOS ARM64 Presets (Recommended for Apple Silicon)

For Development Work:

# ARM64-only development build with ROM testing
cmake --preset macos-dev
cmake --build --preset macos-dev

# ARM64-only debug build 
cmake --preset macos-debug
cmake --build --preset macos-debug

# ARM64-only release build
cmake --preset macos-release  
cmake --build --preset macos-release

For Distribution:

# Universal binary (ARM64 + x86_64) - use only when needed for distribution
cmake --preset macos-debug-universal
cmake --build --preset macos-debug-universal

cmake --preset macos-release-universal
cmake --build --preset macos-release-universal

🔧 Why This Fixes Architecture Errors

Problem: The original presets used CMAKE_OSX_ARCHITECTURES: "x86_64;arm64" which forced CMake to build universal binaries. This caused issues because:

Dependencies like Abseil tried to use x86 SSE instructions (-msse4.1)
These instructions don't exist on ARM64 processors
Build failed with "unsupported option '-msse4.1' for target 'arm64-apple-darwin'"

Solution: The new ARM64-only presets use CMAKE_OSX_ARCHITECTURES: "arm64" which:

✅ Only targets ARM64 architecture
✅ Prevents x86-specific instruction usage
✅ Uses ARM64 optimizations instead
✅ Builds much faster (no cross-compilation)

📋 Available Presets

Preset Name	Architecture	Purpose	ROM Tests
`macos-dev`	ARM64 only	Development	✅ Enabled
`macos-debug`	ARM64 only	Debug builds	❌ Disabled
`macos-release`	ARM64 only	Release builds	❌ Disabled
`macos-debug-universal`	Universal	Distribution debug	❌ Disabled
`macos-release-universal`	Universal	Distribution release	❌ Disabled

🚀 Quick Start

For most development work on Apple Silicon:

# Clean build
rm -rf build

# Configure for ARM64 development
cmake --preset macos-dev

# Build
cmake --build --preset macos-dev

# Run tests  
cmake --build --preset macos-dev --target test

🛠️ IDE Integration

VS Code with CMake Tools:

Open Command Palette (Cmd+Shift+P)
Run "CMake: Select Configure Preset"
Choose macos-dev or macos-debug

CLion:

Go to Settings → Build, Execution, Deployment → CMake
Add new profile with preset macos-dev

Xcode:

# Generate Xcode project
cmake --preset macos-debug -G Xcode
open build/yaze.xcodeproj

🔍 Troubleshooting

If you still get architecture errors:

Clean completely: rm -rf build
Check preset: Ensure you're using an ARM64 preset (not universal)
Verify configuration: Check that CMAKE_OSX_ARCHITECTURES shows only arm64

# Verify architecture setting
cmake --preset macos-debug
grep -A 5 -B 5 "CMAKE_OSX_ARCHITECTURES" build/CMakeCache.txt

📝 Notes

ARM64 presets: Fast builds, no architecture conflicts
Universal presets: Slower builds, for distribution only
Deployment target: ARM64 presets use macOS 11.0+ (when Apple Silicon was introduced)
Universal presets: Still support macOS 10.15+ for backward compatibility
