Unit-conversion candidate distinct from the already-published cf-units (SciTools/Iris climate stack): gimli.units is CSDMS's object-oriented Cython interface to UDUNITS-2, used for generic earth-science unit conversion rather than CF-convention data. Builds directly from an upstream checkout (mirroring upstream's own test.yml cibuildwheel job) since upstream stopped publishing an sdist at 0.3.3; expat 2.6.0 and UDUNITS-2 2.2.28 are vendored under extern/ and compiled to static libs via CMake in the project's own before-build commands, with no external dependency beyond a C compiler and cmake (both already in the manylinux_riscv64 image) - unlike cf-units, no EPEL workaround is needed since upstream already builds UDUNITS-2 from source on every platform. Widens license-files to ship the vendored expat/UDUNITS-2 notices alongside gimli.units' own LICENSE.md, matching the netcdf4/cf-units precedent.

gimli.units0.4.1Cython extension that statically links vendored expat and UDUNITS-2 for object-oriented unit conversion. Upstream publishes no riscv64 wheel.
Mirrors upstream's
test.ymlbuild-wheels job, checked out at the release tag since upstream stopped publishing an sdist at 0.3.3.Differs from upstream
Testing
License: wheel bundles expat (MIT) and UDUNITS-2 (free, BSD-style UCAR licence); upstream's license-files names only its own LICENSE.md, so the patch adds both.
Patches
0001-pyproject-widen-license-files-to-cover-vendored-expat-udunits2.patch- To upstream. Without it neither vendored licence ships in the wheel; reproduces on every platform, not riscv64-only.CI running on cp312/cp313/cp314, manylinux and musllinux.
