Graeme, All,

On 2024-01-29 11:54 -0800, Graeme Smecher spake thusly:

See package/python-numpy/python-numpy.mk: it has proper lapack and blas
handling for the target variant, but indeed the host variant is left in
the dark.

Or rather just happenstance that you found it first...

Indeed it is not the proper solutoin. The proper way is to edit
package/python-numpy/python-numpy.mk and add:
    HOST_PYTHON_NUMPY_CONF_OPTS = -Dblas="" -Dlapack=""

Hopefully they are not needed for the host variant, because we not have
host-lapack or host-openblas.

Care to send a patch, please?

Regards,
Yann E. MORIN.
