pins in the relevant CI/lock files, like NumPy
and SciPy also do.[!WARNING] Please do not add a runtime dependency on these wheels if you're not NumPy or SciPy. This is not supported and likely to lead to breakage or symbol conflicts due to either changes in this repository or due to NumPy or SciPy starting to depend on a particular version of this package.
First, tarballs are built using do_build_lib
in tools/build_steps.sh
(on
posix in a docker and drectly on macos) or build_openblas.sh
on windows.
Then the shared object and header files from the tarball are used to build the
wheel via tools/build_wheel.sh
, and the wheels uploaded to
https://anaconda.org/scientific=python-nightly-wheels/scipyopenblas32 and
https://anaconda.org/scientific=python-nightly-wheels/scipyopenblas64 via
tools/upload_to_anaconda_staging.sh
. For a release, the wheels are uploaded
to PyPI by downloading them via tools/dowlnload-wheels.py and uploading via
twine.
The wheel is self-contained, it includes all needed gfortran support libraries. On windows, this is a single DLL.
The wheel supplies interfaces for building and using OpenBLAS in a python project like SciPy or NumPy:
get_include_dir()
, get_lib_dir()
and get_library()
for use in compiler
or project argumentsget_pkg_config()
will return a multi-line text that can be saved into a
file and used with pkg-config for build systems like meson. This works around
the problem of relocatable pkg-config
files
since the windows build uses pkgconfiglite v0.28 which does not support
--define-prefix
.
