So, the host variant needs python-pycparser, but the target variantdoes
not?

I would have expect either:
    PYTHON_CFFI_DEPENDENCIES += host-python-pycparser

or:
    PYTHON_CFFI_DEPENDENCIES += python-pycparser

Care to shed some light on this, please?

Target variant doesn't need pycparser. cffi's setup.py seems to
distinguish, if we install real package or cross-compiled one:

        install_requires=[
            'pycparser',
        ] if cpython else [],

I don't understand how this "if cpython" is relevant to make the
different between the native (host) variant or the cross-compiled
(target) variant. cpython is defined as is:

    cpython = ('_cffi_backend' not in sys.builtin_module_names)

Can you give some more details?

Thanks,

Thomas

Yegor and I briefly discussed this on IRC yesterday, but I'm not really
convinced by this reply either. I forgot to reply yesterday...

What I understand, however, is that they want to differentiate between
cpython (the 'ofiicial' native Python interpreter), and PyPy (the Python
interpreter written in Python).

Of course, I don't see how this all works. It seems in
cross-compilation. there differentiation criterai beliveves it is
running under PyPy amd thus they do not need pycparser.

But thtat's just incorrect, because we may have a host-python with
cffi_backend at one point, and thus the check above will eventually
differentiate toward cpython, and we'd nreak again.

So, two things:
  - their check is wrong,
  - we probably need host-pycparser

At least, that's what I understood...

Regards,
Yann E. MORIN.

Well, I meant that we should need host-pycparser as a dependency of
python-cffi.

But anyway, there is more to this: we really need to understand what is
going on...

I still don't really understand the difference between host and target
cffi requirements, but at least I can now shed some light on cpython
definition. Below is sys.builtin_module_names() description:

"A tuple of strings giving the names of all modules that are compiled
into this Python interpreter."

So our host-python version won't show '_cffi_backend' even if it is
installed on the system, because it is not built-in. But PyPy
(http://pypy.org/) comes with this backend out of the box.

Will debug further.

@Oli: what are you using cffi for?

Hello Yegor, All

 It's been some time since I worked with buildroot. At the time I was
trying to include smbus-cffi <https://pypi.python.org/pypi/smbus-cffi> into
buildroot's python modules and this needs cffi. I wanted to try an
alternative module to pysmbus which did not integrate right away.
 Meanwhile the module pysmbus <https://pypi.python.org/pypi/pysmbus/0.1>
has been included in buildroot, thank you.

Happy New Year, oli

Thanks for clarification. I'll take a look at smbus-cffi.
