- Add gcc-c++ and cmake to dependencies
- Create libzmq.pc file if missing (CentOS 7 issue)
- Set PKG_CONFIG_PATH through CIBW_ENVIRONMENT_LINUX
- Add protobuf-devel to ensure all headers are available
- Fix shell variable escaping in heredoc
- Add yum cache cleaning and updating
- Make package installations more resilient with fallbacks
- Use pkgconfig instead of pkg-config (CentOS 7 naming)
- Handle optional packages that might not be available
- Add error handling for package installation failures
- Build pure Python packages (leann-core, leann) with standard build tool
- Only use cibuildwheel for C extension packages (leann-backend-hnsw, leann-backend-diskann)
- Build pure Python packages only once on ubuntu-latest
- Add Python setup for building pure packages
- Add package listing step for debugging
- Upgrade all GitHub Actions to v4 (v3 is deprecated)
- Use manual git checkout in manylinux2014 containers to avoid Node.js issues
- Update artifact naming to ensure uniqueness (required by v4)
- Add fail-fast: false to build strategies
- This maintains manylinux2014 compatibility while using latest actions
- Use cibuildwheel for professional wheel building
- Specifically use manylinux2014 for Google Colab compatibility
- Supports Python 3.9-3.12 on Linux and macOS
- Handles monorepo structure with separate builds per package
- Includes basic import tests for each package
- This should resolve compatibility issues with older systems like Google Colab
