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
- Replace file-based validation with directory name check
- Now simply checks if current directory is named 'nostr_core_lib'
- More reliable and clearer error messages for customers
- Fixes issue where customers get validation errors when running from properly named directories
- Added BUILD_DIR=/home/teknari/Sync/Programming/VibeCoding/nostr_core_lib to capture absolute build directory
- Changed relative paths to absolute paths in archive extraction
- Fixes 'No such file or directory' error when build.sh is called from customer Makefiles
- Maintains backward compatibility for all existing use cases
- Moved old tests from tests/old/ to main tests/ directory
- Renamed nostr_test_bip32.c to bip32_test.c for consistency
- Renamed nostr_crypto_test.c to crypto_test.c for consistency
- Renamed wss_test.c and moved from old directory
- Fixed unused variable warning in bip32_test.c
- Updated build system and workspace rules
- Cleaned up old compiled test executables
- Updated nostr_common.h and core_relays.c
- Removed obsolete nostr_core.h.old backup file
This consolidates all active tests into the main directory and removes
outdated test files while maintaining a clean, organized structure.
- Add secp256k1 auto-building rule for x64 target
- Fix customer build errors with missing secp256k1/.libs/libsecp256k1.a
- Force clean rebuild when secp256k1 library is missing
- Customers can now run 'make' directly without manual dependency building
- Maintains existing ARM64 cross-compilation auto-building functionality
- Remove nostr_core/version.c from Makefile LIB_SOURCES to fix submodule build failures
- Remove cjson/ from .gitignore and add cjson source files to repository
- Consolidate cJSON.h into cjson/ directory (remove duplicate from nostr_core/)
- Simplify build.sh versioning to only manage git tags and VERSION file
- Update examples/version_test.c to work without version functions
- Consumer projects can now use 'make' directly without missing file errors
- 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
