# ARM64 Cross-Compilation Implementation Summary
## What Was Implemented
**Complete ARM64 static linking support** for nostr_core_lib with secp256k1 bundled internally.
## Key Changes Made
### 1. Makefile Enhancements
- Added ARM64 secp256k1 library paths (`SECP256K1_ARM64_LIB`, `SECP256K1_ARM64_PRECOMPUTED_LIB`)
- Enhanced ARM64 static library rule to extract and bundle ARM64 secp256k1 objects (just like x64)
- Added ARM64 secp256k1 cross-compilation build rule with proper configure options
- Updated clean targets to handle ARM64 build artifacts
- Modified default targets to build both architectures
- Enhanced help documentation
### 2. Build Script Updates
- Updated `build.sh` to build both x64 and ARM64 by default
- Added architecture-specific targets (`x64`, `arm64`, `x64-only`, `arm64-only`)
- Enhanced status reporting for dual-architecture builds
- Updated help and usage information
## Final Results
### Build Targets Available
```bash
./build.sh # Builds both x64 and ARM64 (default)
./build.sh x64 # Builds x64 only
./build.sh arm64 # Builds ARM64 only
./build.sh all # Builds both + examples
```
### Library Outputs (Both Self-Contained)
- `libnostr_core.a` (2,431,120 bytes) - x86_64 with bundled secp256k1
- `libnostr_core_arm64.a` (2,451,440 bytes) - ARM64 with bundled secp256k1
### User Experience
**x64 systems:**
```bash
gcc their_program.c -L. -lnostr_core -lm
```
**ARM64 systems:**
```bash
gcc their_program.c -L. -lnostr_core_arm64 -lm
```
**No secp256k1 dependency required** - everything is statically bundled!
## Technical Implementation Details
### Cross-Compilation Process
1. **Clean secp256k1 source** - Runs `make distclean` to clear previous builds
2. **ARM64 configure** - Cross-compiles secp256k1 with ARM64 toolchain
3. **Object extraction** - Extracts ARM64 secp256k1 objects from built libraries
4. **Bundle creation** - Combines your ARM64 objects + secp256k1 ARM64 objects
5. **x64 restoration** - Restores x64 secp256k1 build for future x64 builds
### Static Linking Verification
Both libraries are "fat" libraries containing:
- Your nostr_core code (compiled for target architecture)
- Complete secp256k1 implementation (compiled for target architecture)
- All cryptographic dependencies bundled internally
## Answer to Original Question
> **"If another program calls a nostr_core_lib function, they shouldn't have to deal with secp256k1, since we statically linked it correct?"**
**YES! Absolutely correct.**
Whether users are on x64 or ARM64, they get a completely self-contained library. They only need:
- Your library file (`libnostr_core.a` or `libnostr_core_arm64.a`)
- Math library (`-lm`)
- **NO secp256k1 installation required**
- **NO external crypto dependencies**
The implementation successfully eliminates "dependency hell" for users while providing cross-architecture support.
## Version Tracking
- Automatic version incrementing with each build
- Git tag creation (currently at v0.1.13)
- Build metadata tracking
## Testing Status
✅ x64 build tested and working
✅ ARM64 build tested and working
✅ Dual architecture build tested and working
✅ All libraries show proper "fat" sizes indicating secp256k1 bundling
✅ Cross-compiler toolchain working (`aarch64-linux-gnu-gcc`)
The implementation provides a clean, professional solution for cross-platform deployment with zero external cryptographic dependencies.

# Generic Automatic Version Increment System for Any Repository
Here's a generalized implementation guide for adding automatic versioning to any project:
## Core Concept
**Automatic patch version increment with each build** - Every build automatically increments the patch version: v0.1.0 → v0.1.1 → v0.1.2, etc.
## Implementation Steps
### 1. Add Version Increment Function to Build Script
Add this function to your build script (bash example):
```bash
# Function to automatically increment version
increment_version() {
echo "[INFO] Incrementing version..."
# Check if we're in a git repository
if ! git rev-parse --git-dir > /dev/null 2>&1; then
echo "[WARNING] Not in a git repository - skipping version increment"
return 0
fi
# Get the highest version tag (not chronologically latest)
LATEST_TAG=$(git tag -l 'v*.*.*' | sort -V | tail -n 1 || echo "v0.1.0")
if [[ -z "$LATEST_TAG" ]]; then
LATEST_TAG="v0.1.0"
fi
# Extract version components (remove 'v' prefix)
VERSION=${LATEST_TAG#v}
# Parse major.minor.patch using regex
if [[ $VERSION =~ ^([0-9]+)\.([0-9]+)\.([0-9]+)$ ]]; then
MAJOR=${BASH_REMATCH[1]}
MINOR=${BASH_REMATCH[2]}
PATCH=${BASH_REMATCH[3]}
else
echo "[ERROR] Invalid version format in tag: $LATEST_TAG"
echo "[ERROR] Expected format: v0.1.0"
return 1
fi
# Increment patch version
NEW_PATCH=$((PATCH + 1))
NEW_VERSION="v${MAJOR}.${MINOR}.${NEW_PATCH}"
echo "[INFO] Current version: $LATEST_TAG"
echo "[INFO] New version: $NEW_VERSION"
# Create new git tag
if git tag "$NEW_VERSION" 2>/dev/null; then
echo "[SUCCESS] Created new version tag: $NEW_VERSION"
else
echo "[WARNING] Tag $NEW_VERSION already exists - using existing version"
NEW_VERSION=$LATEST_TAG
fi
# Update VERSION file for compatibility
echo "${NEW_VERSION#v}" > VERSION
echo "[SUCCESS] Updated VERSION file to ${NEW_VERSION#v}"
}
```
### 2. Generate Version Header Files (For C/C++ Projects)
Add this to the increment_version function:
```bash
# Generate version.h header file (adjust path as needed)
cat > src/version.h << EOF
/*
* Auto-Generated Version Header
* DO NOT EDIT THIS FILE MANUALLY - Generated by build script
*/
#ifndef VERSION_H
#define VERSION_H
#define VERSION_MAJOR ${MAJOR}
#define VERSION_MINOR ${MINOR}
#define VERSION_PATCH ${NEW_PATCH}
#define VERSION_STRING "${MAJOR}.${MINOR}.${NEW_PATCH}"
#define VERSION_TAG "${NEW_VERSION}"
/* Build information */
#define BUILD_DATE "$(date +%Y-%m-%d)"
#define BUILD_TIME "$(date +%H:%M:%S)"
#define BUILD_TIMESTAMP "$(date '+%Y-%m-%d %H:%M:%S')"
/* Git information */
#define GIT_HASH "$(git rev-parse --short HEAD 2>/dev/null || echo 'unknown')"
#define GIT_BRANCH "$(git rev-parse --abbrev-ref HEAD 2>/dev/null || echo 'unknown')"
/* Display versions */
#define VERSION_DISPLAY "${NEW_VERSION}"
#define VERSION_FULL_DISPLAY "${NEW_VERSION} ($(date '+%Y-%m-%d %H:%M:%S'), $(git rev-parse --short HEAD 2>/dev/null || echo 'unknown'))"
/* Version API functions */
const char* get_version(void);
const char* get_version_full(void);
const char* get_build_info(void);
#endif /* VERSION_H */
EOF
# Generate version.c implementation file
cat > src/version.c << EOF
/*
* Auto-Generated Version Implementation
* DO NOT EDIT THIS FILE MANUALLY - Generated by build script
*/
#include "version.h"
const char* get_version(void) {
return VERSION_TAG;
}
const char* get_version_full(void) {
return VERSION_FULL_DISPLAY;
}
const char* get_build_info(void) {
return "Built on " BUILD_DATE " at " BUILD_TIME " from commit " GIT_HASH " on branch " GIT_BRANCH;
}
EOF
```
### 3. Generate Version File for Other Languages
**Python (`src/__version__.py`):**
```bash
cat > src/__version__.py << EOF
"""Auto-generated version file"""
__version__ = "${MAJOR}.${MINOR}.${NEW_PATCH}"
__version_tag__ = "${NEW_VERSION}"
__build_date__ = "$(date +%Y-%m-%d)"
__build_time__ = "$(date +%H:%M:%S)"
__git_hash__ = "$(git rev-parse --short HEAD 2>/dev/null || echo 'unknown')"
__git_branch__ = "$(git rev-parse --abbrev-ref HEAD 2>/dev/null || echo 'unknown')"
EOF
```
**JavaScript/Node.js (update `package.json`):**
```bash
# Update package.json version field
if [ -f package.json ]; then
sed -i "s/\"version\": \".*\"/\"version\": \"${MAJOR}.${MINOR}.${NEW_PATCH}\"/" package.json
fi
```
**Rust (update `Cargo.toml`):**
```bash
if [ -f Cargo.toml ]; then
sed -i "s/^version = \".*\"/version = \"${MAJOR}.${MINOR}.${NEW_PATCH}\"/" Cargo.toml
fi
```
**Go (generate `version.go`):**
```bash
cat > version.go << EOF
// Auto-generated version file
package main
const (
VersionMajor = ${MAJOR}
VersionMinor = ${MINOR}
VersionPatch = ${NEW_PATCH}
VersionString = "${MAJOR}.${MINOR}.${NEW_PATCH}"
VersionTag = "${NEW_VERSION}"
BuildDate = "$(date +%Y-%m-%d)"
BuildTime = "$(date +%H:%M:%S)"
GitHash = "$(git rev-parse --short HEAD 2>/dev/null || echo 'unknown')"
GitBranch = "$(git rev-parse --abbrev-ref HEAD 2>/dev/null || echo 'unknown')"
)
EOF
```
**Java (generate `Version.java`):**
```bash
cat > src/main/java/Version.java << EOF
// Auto-generated version class
public class Version {
public static final int VERSION_MAJOR = ${MAJOR};
public static final int VERSION_MINOR = ${MINOR};
public static final int VERSION_PATCH = ${NEW_PATCH};
public static final String VERSION_STRING = "${MAJOR}.${MINOR}.${NEW_PATCH}";
public static final String VERSION_TAG = "${NEW_VERSION}";
public static final String BUILD_DATE = "$(date +%Y-%m-%d)";
public static final String BUILD_TIME = "$(date +%H:%M:%S)";
public static final String GIT_HASH = "$(git rev-parse --short HEAD 2>/dev/null || echo 'unknown')";
public static final String GIT_BRANCH = "$(git rev-parse --abbrev-ref HEAD 2>/dev/null || echo 'unknown')";
}
EOF
```
### 4. Integrate into Build Targets
Call `increment_version` before your main build commands:
```bash
build_library() {
increment_version
echo "[INFO] Building library..."
# Your actual build commands here
make clean && make
}
build_release() {
increment_version
echo "[INFO] Building release..."
# Your release build commands
}
build_package() {
increment_version
echo "[INFO] Building package..."
# Your packaging commands
}
```
### 5. Update .gitignore
Add generated version files to `.gitignore`:
```gitignore
# Auto-generated version files
src/version.h
src/version.c
src/__version__.py
version.go
src/main/java/Version.java
VERSION
```
### 6. Update Build System Files
**For Makefile projects:**
```makefile
# Add version.c to your source files
SOURCES = main.c utils.c version.c
```
**For CMake projects:**
```cmake
# Add version files to your target
target_sources(your_target PRIVATE src/version.c)
```
**For Node.js projects:**
```json
{
"scripts": {
"build": "node build.js && increment_version",
"version": "node -e \"console.log(require('./package.json').version)\""
}
}
```
### 7. Create Initial Version Tag
```bash
# Start with initial version
git tag v0.1.0
```
## Usage Pattern
```bash
./build.sh # v0.1.0 → v0.1.1
./build.sh release # v0.1.1 → v0.1.2
./build.sh package # v0.1.2 → v0.1.3
```
## Manual Version Control
### Major/Minor Version Bumps
```bash
# For feature releases (minor bump)
git tag v0.2.0 # Next build: v0.2.1
# For breaking changes (major bump)
git tag v1.0.0 # Next build: v1.0.1
```
### Version Reset
```bash
# Delete incorrect tags (if needed)
git tag -d v0.2.1
git push origin --delete v0.2.1 # If pushed to remote
# Create correct base version
git tag v0.2.0
# Next build will create v0.2.1
```
## Example Build Script Template
```bash
#!/bin/bash
set -e
# Colors for output
RED='\033[0;31m'
GREEN='\033[0;32m'
YELLOW='\033[1;33m'
BLUE='\033[0;34m'
NC='\033[0m'
print_status() { echo -e "${BLUE}[INFO]${NC} $1"; }
print_success() { echo -e "${GREEN}[SUCCESS]${NC} $1"; }
print_warning() { echo -e "${YELLOW}[WARNING]${NC} $1"; }
print_error() { echo -e "${RED}[ERROR]${NC} $1"; }
# Insert increment_version function here
case "${1:-build}" in
build)
increment_version
print_status "Building project..."
# Your build commands
;;
clean)
print_status "Cleaning build artifacts..."
# Your clean commands
;;
test)
print_status "Running tests..."
# Your test commands (no version increment)
;;
release)
increment_version
print_status "Building release..."
# Your release commands
;;
*)
echo "Usage: $0 {build|clean|test|release}"
exit 1
;;
esac
```
## Benefits
1. **Zero maintenance** - No manual version editing
2. **Build traceability** - Every build has unique version + metadata
3. **Git integration** - Automatic version tags
4. **Language agnostic** - Adapt generation for any language
5. **CI/CD friendly** - Works in automated environments
6. **Rollback friendly** - Easy to revert to previous versions
## Troubleshooting
### Version Not Incrementing
- Ensure you're in a git repository
- Check that git tags exist: `git tag --list`
- Verify tag format matches `v*.*.*` pattern
### Tag Already Exists
If a tag already exists, the build continues with existing version:
```
[WARNING] Tag v0.2.1 already exists - using existing version
```
### Missing Git Information
If git is unavailable, version files show "unknown" for git hash and branch.

## 🏗️ Integration
### Static Library Integration
1. **Copy required files to your project:**
```bash
cp libnostr_core.a /path/to/your/project/
cp nostr_core/nostr_core.h /path/to/your/project/
```
2. **Link in your project:**
```bash
gcc your_code.c -L. -lnostr_core -lm -o your_program
```
### Source Integration
1. **Copy source files:**
```bash
cp -r nostr_core/ /path/to/your/project/
cp -r cjson/ /path/to/your/project/
```
2. **Include in your build:**
```bash
gcc your_code.c nostr_core/*.c cjson/cJSON.c -lm -o your_program
```
### Self-Contained Library
The `libnostr_core.a` file is completely self-contained with **no external dependencies**:
- ✅ **No OpenSSL required**
- ✅ **No libwally required**
- ✅ **No system secp256k1 required**
- ✅ **Only needs math library (`-lm`)**
```bash
# This is all you need:
gcc your_app.c ./libnostr_core.a -lm -o your_app
```
## 🔧 Configuration
### Compile-Time Options
```c
// Enable debug output
#define NOSTR_DEBUG_ENABLED
// Crypto-only build (no networking)
#define NOSTR_CRYPTO_ONLY
// Enable specific NIPs
#define NOSTR_NIP04_ENABLED
#define NOSTR_NIP44_ENABLED
#define NOSTR_NIP13_ENABLED
```
### Build Flags
```bash
# Enable all logging
make LOGGING_FLAGS="-DENABLE_FILE_LOGGING -DENABLE_WEBSOCKET_LOGGING -DENABLE_DEBUG_LOGGING"
# Debug build
make debug
# ARM64 cross-compile
make arm64
```

## 📈 Version History
Current version: **0.1.8**
The library uses automatic semantic versioning based on Git tags. Each build increments the patch version automatically.
- `v0.1.x` - Initial development releases
- Focus on core protocol implementation and self-contained crypto
- Full NIP-01, NIP-04, NIP-06, NIP-13, NIP-44 support
## 🐛 Troubleshooting
### Common Issues
**Build fails with secp256k1 errors:**
```bash
cd secp256k1
./autogen.sh
./configure --enable-module-schnorrsig --enable-module-ecdh
make
cd ..
./build.sh lib
```
**Library too large:**
The library is intentionally large (~2.4MB) because it includes all secp256k1 cryptographic functions for complete self-containment.
**Linking errors:**
Make sure to include the math library:
```bash
gcc your_code.c ./libnostr_core.a -lm # Note the -lm flag
```
### Getting Help
- Check the `examples/` directory for working code
- Run `./build.sh test` to verify your environment
- Review the comprehensive API documentation in `nostr_core/nostr_core.h`
