Hi Peter,
I managed to get scipy to cross compile, since I was in a hurry, and
have no deeper understanding of python / distutils / setuptools, it
turned out to be an ugly hack (but obviously I was not the first one to
do ugly things there ;) )
Maybe you have had some progress as well, and we can figure out a nicer
solution.
See the attached files, involving openblas, a bbappend for python-numpy
and python-scipy.
Regards,
Matthias
