QuantLib is a C++ library for quantitative finance; the QuantLib PyPI package is its SWIG-generated Python binding, built from the QuantLib-SWIG subproject. Upstream publishes 15 Linux wheels but none for riscv64. The wheel needs the SWIG-generated wrapper that only the release tarball carries, so the workflow mirrors upstream's make-tarballs job: it builds both QuantLib and QuantLib-SWIG dist tarballs with SWIG 4.4.1 on x86, then feeds them to cibuildwheel on riscv64, where upstream's own .ci/wheels/before_all scripts install the Boost headers and build libQuantLib. setup.py writes py_limited_api=cp39, so one abi3 wheel covers every non-free-threaded interpreter and cp314t gets its own build against a thread-safe-observer libQuantLib, as upstream does.

quantlib1.43Compiles the QuantLib C++ quantitative-finance library and its SWIG-generated Python binding. Upstream publishes no riscv64 wheel.
Mirrors upstream's
wheels.yml, reusing itsmake-tarballsjob and its.ci/wheels/before_all_linux*.shscripts.Differs from upstream
Matrix:
cp39-abi3pluscp314-cp314t.setup.pysetspy_limited_api=cp39, so one wheel covers every non-free-threaded interpreter and is built on cp39, the oldest version its tag claims. The free-threaded wheel is not abi3 and links a thread-safe-observer build of libQuantLib.Testing
License: OK
Built on cp39; 211 passed, 1 skipped.
