texture2ddecoder: add build-texture2ddecoder.yml for riscv64 wheels - #1594
Merged
Conversation
Pure C++ setuptools extension (no Rust/PyO3, no SIMD intrinsics) - builds a single cp311-abi3 wheel from cp312/cp313/cp314. Upstream ships no git tags, so the workflow pins the release commit that matches the 1.0.6 sdist byte-for-byte. cp314t is dropped: setup.py's own bdist_wheel override unconditionally sets Py_LIMITED_API for CPython >=3.11 with no Py_GIL_DISABLED guard, which hard-errors under a free-threaded interpreter (reproduced locally); upstream ships no free-threaded wheel either.

Matrix: cp312/cp313/cp314, no cp314t -
setup.py's own abi3 tagging has noPy_GIL_DISABLEDguard, so a free-threaded build definesPy_LIMITED_APIand hits CPython's own compile-time error; upstream ships no free-threaded wheel either.Testing
