- Introduced a comprehensive build system that supports multiple platforms (Linux, macOS, Windows, Android) using pure Go builds (`CGO_ENABLED=0`). - Updated all build and test scripts to ensure compatibility with the new purego approach, allowing for dynamic loading of `libsecp256k1` at runtime. - Added detailed documentation on the build process, platform detection, and deployment options. - Enhanced CI/CD workflows to automate builds for all supported platforms and include necessary libraries in releases. - Updated `.gitignore` to exclude build output files. - Created new documentation files for deployment and multi-platform build summaries.

# Multi-Platform Build System - Implementation Summary
|
|
|
|
## Created Scripts
|
|
|
|
### 1. `scripts/build-all-platforms.sh`
|
|
**Purpose:** Master build script for all platforms
|
|
|
|
**Features:**
|
|
- Builds for Linux (AMD64, ARM64)
|
|
- Builds for macOS (AMD64, ARM64) - pure Go
|
|
- Builds for Windows (AMD64)
|
|
- Builds for Android (ARM64, AMD64) - if NDK available
|
|
- Copies platform-specific libsecp256k1 libraries
|
|
- Generates SHA256 checksums
|
|
- Handles cross-compilation with appropriate toolchains
|
|
|
|
**Output Location:** `build/` directory
|
|
|
|
### 2. `scripts/platform-detect.sh`
|
|
**Purpose:** Platform detection and binary/library name resolution
|
|
|
|
**Functions:**
|
|
- `detect` - Returns current platform (e.g., linux-amd64)
|
|
- `binary <version>` - Returns binary name for platform
|
|
- `library` - Returns library name for platform
|
|
|
|
**Usage in other scripts:**
|
|
```bash
|
|
source scripts/platform-detect.sh
|
|
PLATFORM=$(detect_platform)
|
|
BINARY=$(get_binary_name "$VERSION")
|
|
```
|
|
|
|
### 3. `scripts/run-orly.sh`
|
|
**Purpose:** Universal launcher for platform-specific binaries
|
|
|
|
**Features:**
|
|
- Auto-detects platform
|
|
- Selects correct binary from build/
|
|
- Sets appropriate library path (LD_LIBRARY_PATH, DYLD_LIBRARY_PATH, PATH)
|
|
- Passes all arguments to binary
|
|
- Shows helpful error if binary not found
|
|
|
|
**Usage:**
|
|
```bash
|
|
./scripts/run-orly.sh [arguments]
|
|
```
|
|
|
|

## Quick Start Guide
|
|
|
|
### Building
|
|
|
|
```bash
|
|
# Build all platforms
|
|
./scripts/build-all-platforms.sh
|
|
|
|
# Output in build/ directory
|
|
ls -lh build/
|
|
```
|
|
|
|
### Running
|
|
|
|
```bash
|
|
# Auto-detect and run
|
|
./scripts/run-orly.sh
|
|
|
|
# Or run specific binary
|
|
export LD_LIBRARY_PATH=./build:$LD_LIBRARY_PATH
|
|
./build/orly-v0.25.0-linux-amd64
|
|
```
|
|
|
|
### Testing
|
|
|
|
```bash
|
|
# Run tests (auto-configures library path)
|
|
./scripts/test.sh
|
|
|
|
# Run specific test suite
|
|
./scripts/test_policy.sh
|
|
```
|
|
|
|
### Deploying
|
|
|
|
```bash
|
|
# Deploy to production (builds with CGO, copies library)
|
|
./scripts/deploy.sh
|
|
```
|
|
|
|
## CI/CD Integration
|
|
|
|
### GitHub Actions Workflow
|
|
On git tag push (e.g., `v0.25.1`):
|
|
1. Installs libsecp256k1 from source
|
|
2. Installs cross-compilers
|
|
3. Builds for all 5 platforms
|
|
4. Copies platform-specific libraries
|
|
5. Generates SHA256 checksums
|
|
6. Creates GitHub release with all artifacts
|
|
|
|
### Release Artifacts
|
|
Each release includes:
|
|
- 5 binary files (Linux x2, macOS x2, Windows)
|
|
- 3 library files (Linux x2, Windows)
|
|
- 1 checksum file
|
|
- Auto-generated release notes
|
|
|
|
## Distribution
|
|
|
|
### For End Users
|
|
|
|
Provide:
|
|
1. Platform-specific binary
|
|
2. Corresponding library (if CGO build)
|
|
3. Checksum for verification
|
|
|
|
### Example Distribution Package
|
|
|
|
```
|
|
orly-v0.25.0-linux-amd64.tar.gz
|
|
├── orly
|
|
├── libsecp256k1.so
|
|
├── README.txt
|
|
└── SHA256SUMS.txt
|
|
```
|
|
|
|
### Running Distributed Binary
|
|
|
|
Linux:
|
|
```bash
|
|
chmod +x orly
|
|
export LD_LIBRARY_PATH=.:$LD_LIBRARY_PATH
|
|
./orly
|
|
```
|
|
|
|
macOS (pure Go, no library needed):
|
|
```bash
|
|
chmod +x orly
|
|
./orly
|
|
```
|
|
|
|
Windows:
|
|
```powershell
|
|
# Library auto-detected in same directory
|
|
.\orly.exe
|
|
```
|
|
|
|
## Performance Notes
|
|
|
|
### CGO vs Pure Go
|
|
|
|
**CGO (Linux, Windows):**
|
|
- ✓ 2-3x faster crypto operations
|
|
- ✓ Smaller binary size
|
|
- ✗ Requires library at runtime
|
|
- ✓ Recommended for production servers
|
|
|
|
**Pure Go (macOS):**
|
|
- ✗ Slower crypto operations
|
|
- ✗ Larger binary size
|
|
- ✓ Self-contained, no dependencies
|
|
- ✓ Recommended for desktop/development
|
|
|
|
## Maintenance
|
|
|
|
### Adding New Platform
|
|
|
|
1. Add build target to `scripts/build-all-platforms.sh`
|
|
2. Add platform detection to `scripts/platform-detect.sh`
|
|
3. Add library handling for new platform
|
|
4. Update documentation
|
|
5. Test build and execution
|
|
|
|
### Updating libsecp256k1
|
|
|
|
1. Update `pkg/crypto/p8k/libsecp256k1.so` (or build from source)
|
|
2. Run `./scripts/build-all-platforms.sh`
|
|
3. Test binaries on each platform
|
|
4. Commit updated binaries to releases
|
|
|
|
## Testing Checklist

## Known Limitations
|
|
|
|
1. **macOS CGO cross-compilation**: Complex setup required (osxcross), uses pure Go instead
|
|
2. **Android**: Requires Android NDK setup, experimental support
|
|
3. **32-bit platforms**: Not currently supported
|
|
4. **RISC-V/other architectures**: Not included, but can be added
|
|
|
|
## Future Enhancements
|
|
|
|
- [ ] ARM32 support (Raspberry Pi)
|
|
- [ ] RISC-V support
|
|
- [ ] macOS with CGO (using osxcross)
|
|
- [ ] iOS builds
|
|
- [ ] Automated testing on all platforms
|
|
- [ ] Docker images for each platform
|
|
- [ ] Static binary builds (musl libc)
