From 019649885c0cefeaf3efc136d5c375d6c867aad6 Mon Sep 17 00:00:00 2001 From: Ludovic Henry Date: Mon, 28 Sep 2026 07:46:56 +0000 Subject: [PATCH 1/3] port: add anastruct 1.7.0 riscv64 wheel build anastruct is a 2D FEA library for structural engineering with two small Cython extensions (celements, cbasic) doing pure floating-point math via libc.math, no numpy C-API, no arch-specific code. Mirrors upstream's own cibuildwheel-based release.yaml, narrowed to manylinux_riscv64, matching its cp310-cp314 build matrix. numpy is pinned to binary-only (our registry carries it for riscv64; it is both a build-time and runtime dependency). Cython is left unrestricted since our registry only has riscv64 wheels for cp312+, and its own sdist builds cleanly for cp310/cp311, as it already does for crick. --- .github/workflows/build-anastruct.yml | 125 ++++++++++++++++++++++++++ docs/packages/anastruct.yaml | 5 ++ 2 files changed, 130 insertions(+) create mode 100644 .github/workflows/build-anastruct.yml create mode 100644 docs/packages/anastruct.yaml diff --git a/.github/workflows/build-anastruct.yml b/.github/workflows/build-anastruct.yml new file mode 100644 index 00000000000..45a1b50215e --- /dev/null +++ b/.github/workflows/build-anastruct.yml @@ -0,0 +1,125 @@ +# SPDX-FileCopyrightText: 2026 The RISE Project +# SPDX-License-Identifier: MIT +--- +# This workflow is based on: https://github.com/ritchie46/anaStruct/blob/release-v1.7.0/.github/workflows/release.yaml +name: Build anastruct wheels (riscv64) + +on: + workflow_dispatch: + inputs: + version: + description: 'Version glob to (re)build;
