pypi.riseproject.dev has never published a musllinux_riscv64 Pillow
wheel (manylinux_riscv64 only, plus a legacy untagged linux_riscv64
wheel for cp39-cp312 that pip happens to accept on musl too), so
PIP_ONLY_BINARY=cysignals,Pillow made cp313/cp314/cp314t-musllinux
fail outright installing the test-only Pillow dependency ("Could not
find a version that satisfies the requirement Pillow (from versions:
none)"). Drop Pillow from PIP_ONLY_BINARY so pip falls back to its
sdist there; the jpeg/png/tiff/webp/zlib -dev packages already
installed earlier in the same container for leptonica/tesseract cover
what Pillow's setup.py auto-detects and needs.

tesserocr2.11.0Cython wrapper around the tesseract OCR engine and the leptonica image library. Upstream publishes no riscv64 wheel.
Mirrors upstream's own
build.yml.Differs from upstream
before-all- needed for the packaged suite to actually run OCRTesting
License: Wheel bundles libleptonica (BSD-2-Clause) and libtesseract (Apache-2.0); their licence texts are added since upstream's own package ships neither.
Patches
0001-package-the-leptonica-and-tesseract-licences-with-t.patch- Inappropriate [riscv64-specific build dependency]. Adds both licence texts so setuptools' default glob bundles them; reproduces off riscv64 too.Built on cp312; results pending first CI run.
