BREAKING CHANGE: Library now requires system-installed dependencies
Major Changes:
- Convert secp256k1 from bundled static lib to system dependency
- Convert OpenSSL from bundled static lib to system dependency
- Convert curl from bundled static lib to system dependency
- Update build.sh with pkg-config detection and fallback logic
- Remove all static library extraction/building logic
- Update README.md with new dependency requirements and installation
Build System:
- Add detect_system_secp256k1() with pkg-config support
- Add detect_system_openssl() with pkg-config support
- Add detect_system_curl() with pkg-config support
- Remove secp256k1 building/extraction from ar archive
- Update CFLAGS and LIBS to use system library variables
- Clear error messages for missing dependencies with install commands
Documentation:
- Add system dependency installation for Ubuntu/Debian/CentOS/macOS
- Update all compile/link examples to include -lssl -lcrypto -lcurl -lsecp256k1
- Remove references to 'self-contained' and 'no external dependencies'
- Update integration examples throughout README
Benefits:
- Smaller library size (only internal code bundled)
- Automatic security updates via system package manager
- Standard Linux library distribution pattern
- Reduced build complexity
- Better system integration with pkg-config
Required Installation:
Ubuntu/Debian: sudo apt install libssl-dev libcurl4-openssl-dev libsecp256k1-dev
CentOS/RHEL: sudo yum install openssl-devel libcurl-devel libsecp256k1-devel
macOS: brew install openssl curl secp256k1
- Complete C library template with OpenSSL-based crypto
- Comprehensive build system (Makefile, build.sh)
- Example code and test suite
- Documentation and usage guides
- Cross-platform compatibility (x64/ARM64)
- Production-ready structure for C library projects
