Building redistributable binaries#
python -m build or
pip wheel is used to build a SciPy wheel,
that wheel will rely on external shared libraries (at least for BLAS/LAPACK and
a Fortran compiler runtime library, perhaps other libraries). Such wheels
therefore will only run on the system on which they are built. See
the pypackaging-native content under “Building and installing or uploading
artifacts” for more context on that.
A wheel like that is therefore an intermediate stage to producing a binary that
can be distributed. That final binary may be a wheel - in that case, run
delocate (macOS) or
delvewheel (Windows) to
vendor the required shared libraries into the wheel.
The final binary may also be in another packaging format (e.g., a
.conda package). In that case, there are packaging
ecosystem-specific tools to first install the wheel into a staging area, then
making the extension modules in that install location relocatable (e.g., by
rewriting RPATHs), and then repackaging it into the final package format.
