Future ARM64 Build Enhancement Plan

This document outlines the plan for adding comprehensive ARM64 support to the g4f build system.

Current Status

• macOS ARM64: ✅ Supported (native runners)
• Linux ARM64: ⏳ Requires ARM64 runners or cross-compilation
• Windows ARM64: ⏳ Requires ARM64 runners or cross-compilation

Implementation Plan for ARM64 Support

Phase 1: Linux ARM64 (Future Enhancement)

# Add to .github/workflows/build-packages.yml
build-linux-exe:
  strategy:
    matrix:
      include:
        - architecture: x64
          runner: ubuntu-latest
          runner-arch: x86_64
        - architecture: arm64
          runner: buildjet-4vcpu-ubuntu-2204-arm  # ARM64 runners
          runner-arch: aarch64

Phase 2: Windows ARM64 (Future Enhancement)

build-windows-exe:
  strategy:
    matrix:
      include:
        - architecture: x64
          runner: windows-latest
          runner-arch: x86_64
        - architecture: arm64  
          runner: windows-latest-arm64  # When available
          runner-arch: arm64

Phase 3: Cross-compilation Support

For environments without native ARM64 runners:

• Use Docker with QEMU emulation
• Configure Nuitka for cross-compilation
• Test compatibility and performance

Benefits of ARM64 Support

1. Performance: Native ARM64 binaries run faster on ARM64 hardware
2. Compatibility: Better support for Apple Silicon Macs and ARM64 Linux systems
3. Future-proofing: ARM64 adoption is increasing across all platforms

Testing Requirements

• Verify ARM64 binaries work on actual ARM64 hardware
• Test performance compared to x64 binaries on ARM64 systems
• Ensure compatibility with all g4f features

Notes

• This is marked as a future enhancement because it requires ARM64 runners or cross-compilation setup
• Current implementation provides a solid foundation for easy expansion
• The build matrix is designed to accommodate additional architectures
