Updates for GNU Radio version >= 3.9.0.0 compatibility.

• Use std::shared_ptr with GNU Radio version 3.9.0.0
• Rebase changes

Use std::shared_ptr with GNU Radio 3.9.0.0

In the released GNU Radio version 3.9.0.0 release, GNU Radio has switched from boost::shared_ptr to std::shared_ptr.

Rebase changes

Rebase changes from:

https://github.com/gnuradio/gnuradio/pull/2840

Testing

I have tested these changes by building GNU Radio version 3.9.0.0 (master) from source and then compiling gr-iio from this feature branch. The build works as expected. I can supply a Docker container that allows this testing to happen in an automated manor.

I used the commit hash c40e82ae17a9dfefc95b15ab22eaf8dbf1a45d29 while building GNU Radio from source :nerd_face:.

I expected upgrade-3.8 to be in master at this point. I need to rebase this feature branch with the changes from upgrade-3.8.

Trying to build this on Ubuntu 20.04 and having issue with cmake

`scott@scott:~/wip/he_gr_iio$ cmake .

Tried getting pybynd up to date by following the Ubuntu 20.04 build from source instructions:

`curl -Lo pybind11.tar.gz https://github.com/pybind/pybind11/archive/v2.4.3.tar.gz

mkdir pybind11 && tar xzf pybind11.tar.gz -C pybind11 --strip-components=1 && cd pybind11 mkdir build && cd build cmake .. -DCMAKE_BUILD_TYPE=Release -DPYBIND11_TEST=OFF make && make install `

Also, a lot of wiki and readme pages need updating before this can be merged

I am working towards getting this integrated into GNU Radio, as per GNU RadioEnhancement Proposals 0017. In short it adds the gr-iio out of tree module in tree.

Currently my efforts are working towards bringing this in tree 🤓 .

This was a work in progress branch before this work started. I would expect this branch to produce build errors.

If you want to use gr-iio take a look at the above pull request, you should be able to check out that branch and compile from source instead of using the out of tree module here 😁 .
