Compiles the mmCIF/PDBx core access library: a pybind11 C++ extension (CMake, flex/bison CIF and dictionary lexer-parsers) wrapped by the pure-Python mmcif.io/mmcif.api layers. Upstream publishes no riscv64 wheel.

Mirrors upstream's own cibuildwheel config - its Linux before-all (yum install cmake bison flex) carries over unchanged from the checkout, unmodified for riscv64.

Differs from upstream

  • Checks out a pinned commit, not a tag - upstream cuts PyPI releases without ever pushing a git tag.

Testing

  • Same as upstream's own wheel test (python -c "from mmcif.io.IoAdapterCore import IoAdapterCore"), plus a .so and licence-file check.

License: OK

Built locally on macOS arm64 (cp312) from the pinned checkout; wheel builds, the compiled-core smoke import passes, and the resulting sdist matches PyPI's 1.1.1 sdist byte-for-byte.
