ngsolve_openblas

ngsolve_openblas vendors the runtime OpenBLAS libraries from scipy-openblas64 and installs them into a top-level netgen_mesher.libs directory.

The package is intended to be used as a runtime dependency for NGSolve wheels that look for their OpenBLAS runtime libraries next to netgen_mesher.

Contents

At wheel build time, the package copies dynamic libraries from the installed scipy-openblas64 build dependency:

• Linux: libscipy_openblas64_.so and its bundled runtime dependencies.
• Windows: libscipy_openblas64_.dll.

The copied files are recorded in the wheel under netgen_mesher.libs/.

Importing ngsolve_openblas immediately loads the bundled runtime libraries with global symbol visibility, so downstream packages can resolve OpenBLAS symbols after declaring this package as a runtime dependency.

Development

Build a wheel with:

python -m pip install build
python -m build --wheel

The generated wheel is platform-specific and uses the platform tag from the scipy-openblas64 wheel used during the build.
