[Buildroot] [PATCH v7 0/4] package/python-scipy: new package

[Jagan Teki]

This is v7 changes from previous version [1].

Changes for v7:
- bump 1.181.2 numpy
- drop 'BR2_PACKAGE_HOST_PYTHON_CYTHON' selection from numpy
- drop python2 dependency from gnuradio.mk
- drop python2 dependency from opencv3.mk
- rephrase commit and comments of fixup npymath.ini
- update commit message of pybind11, scipy
- fix sha256 value of pybind11 LICENCE
- drop 'BR2_PACKAGE_HOST_PYTHON_PYBIND11' selection from scipy 
Changes for v6:
- bump to numpy latest version
- drop python2 dependecy on numpy seelcted packages
- update numpy cross compilation changes
- add pybind11 package
- add latest python-scipy

Any inputs?
Jagan.

[Buildroot] [PATCH v7 1/4] package/python-numpy: Bump to version 1.18.2

[Jagan Teki]

Bump the python-numpy version to 1.18.2, this version
of python-numpy will support python3 only, not python2.

Drop python2 dependency from opencv3, gnuadio packages
since the python support on these are selecting
python-numpy.

[Buildroot] [PATCH v7 2/4] package/python-numpy: fixup npymath.ini for numpy extensions

[Jagan Teki]

From: Esben Haabendal <esben@geanix.com>

Inorder to build the numpy distutils extension packages like
python-scipy, python-numba, it require an explicit pkg-config
path fixup for npymath.ini.

This pkg-config path fixup would update the prefix path of
npymath.ini with actual target staging area where numpy core
was built, so-that numpy distutils extension packages would
explicitly link this config path for their package environment.

Without this extension packages cannot find -lnpymath since
it uses host libraries (like libnpymath.a).

So, attach the post install staging hook with pkg-config
path fixup for npymath.ini.

I don't think pybind11 should be a host package. It's a header-only library
and the headers are used to compile target sources (in your case - scipy).
The headers should be only installed to the staging dir (like spdlog,
for example).

Thanks for commenting on this.

Please check this build log[1], it look phbind11 host package required
to build scipy. Let me know if I miss anything?

As I said, this patch used pybind11 for host so are these tests common
across host vs target? How can I test them?

The test compiles a simple C program and then uses a python program
with pybind11
to ensure that pybind11 is working properly.
