PATCH 1/1 gnuradio: needs host-python2

gnuradio needs host-python2 however there is no way to enforce this so add a dependency on !BR2_PACKAGE_PYTHON3.
Indeed, if BR2_PACKAGE_PYTHON3 is selected, then buildroot will only build host-python3.
This issue was not raised in the previous version of gnuradio as host-python-cheetah was the only dependency and host-python-cheetah enforces python2 through HOST_PYTHON_CHEETAH_NEEDS_HOST_PYTHON however we now have host-python-six and host-python-mako dependencies and it does not seem right to enforces python2 on those packages

Why not just add host-python to _DEPENDENCIES?

This patch did it for me. I've made "make defconfig", select ARM for A8 series, Linaro toolchain and python 2. Then I've just selected gnuradio and its python support.

In this case no host-python3 will be built because we select general Python 2 support for the target (as gnuradio enforces) and hence only host-python will be built.

@Fabrice have you performed "make clean" after adding host-python to the dependencies?

Did you test with python3 enabled for the target ?

Then you will see the problem that Fabrice is facing.

When python3 is enabled for the target, then the default host python version is python3. And due to this, all external host Python modules are installed for host python3, and not available for host python2.

Next branch builds fine however it seems there is outstanding issues:
https://github.com/gnuradio/gnuradio/issues/1842. What should we do until an official release is made with python3 support?

In the mean time, I think I will just apply your patch that adds the "depends on !BR2_PACKAGE_PYTHON3". It's not great, but it's not the only simple approach to resolve the build failures.

In today's Buildroot, if a package needs host Python modules in the Python version which is not the default one, this is not supported, and it will be difficult to support this.

Quoted 3 lines

Not sure what the right solution here is.

Yegor, do you have an idea?

I sent a patch series out some time ago that allows selecting the host python version to be used for creating python packages.

It would allow selecting python2 to be used for host python packages, and still get the host-python3 *interpreter* built if something needs that too.

However, it does not allow:
Building host python packages for multiple python versions. Building host python packages for a different python version than is used on the target, if the target has python.

So if we start with the requirement that we must have host-python-mako for python2, then from that follows that host-python-six and host- python-etcetc must be for python2 as well. And if the target has python, it must also be python2.

Fixing this is hard to to do in buildroot. It ends up with the need to build a package twice, once for python2 and again for python3. Buildroot doesn't like two builds of the same package.

Maybe turn host python packages into two packages? host-python2-mako and host-python3-mako. eval host-python-package creates one or both packages. Maybe that could fit in.

Or maybe that's too complex. You get to pick one python version and all python packages are that version. If you want a python2 only package and a python3 only package, too bad. Port one of them to the other python version. As python3 support grows, this will be less and less of a problem.
