Description
Package name (on PyPI)
lightgbm
Source repository
https://github.com/lightgbm-org/LightGBM
Version(s) requested
4.7.0
Why is this needed?
LightGBM is one of the two mainstream gradient-boosting libraries. Upstream publishes py3-none wheels for macOS, Windows, x86_64 and aarch64 Linux, but nothing for riscv64, so pip install lightgbm on riscv64 falls back to the sdist and needs a CMake/C++ toolchain.
Additional context
Workflow added in #481. The build and auditwheel repair succeed and the wheel carries a real lib_lightgbm.so, but the test phase segfaults in the ranking tests — see #617 for the underlying cause, which is not in LightGBM.
The wheel bundles Eigen, fast_double_parser, fmt and nanoarrow; upstream's license-files = ["LICENSE"] shipped none of their licence texts, so the port carries a patch adding them.

Research direction
Start by reading the workflow added in #481 and the LightGBM 4.7.0 wheel build configuration. Reproduce the build and auditwheel repair, then follow #617 to understand the ranking-test segfault. Done means a riscv64 wheel builds successfully, includes the required bundled license texts, and its test status is understood.
