in prepare() will fix the swig issue, but there seem to be deeper issues...

Build fails for me with

CMake Error at cmake/Modules/UseSWIG.cmake:202 (add_custom_command):
  add_custom_command Wrong syntax.  A TARGET or OUTPUT must be specified.

Thanks for maintaining!

libad9361-iio doesn't exist, but libad9361 is in community and seems to work. please update depends.

Hi, i changed the PKBBUILD regarding your sugggestion. It now builds. Also I changed the pyhon version to 3. The block description .yml gets intalled into to wrong directory (/usr/share/gr-iio/grc/blocks/ instead of /usr/share/gnuradio/grc/blocks/). When I link the files into the new directory I can add it in GCR. Unfortunately I get the following error:

usr/lib/python3.8/site-packages/gnuradio/qtgui/range.py:41: SyntaxWarning: "is not" with a literal. Did you mean "!="? precision = len(temp) if temp is not '0' else 0 Traceback (most recent call last): File "/usr/lib/python3.8/site-packages/iio/init.py", line 30, in <module> from .iio_swig import * File "/usr/lib/python3.8/site-packages/iio/iio_swig.py", line 13, in <module> from . import _iio_swig ImportError: /usr/lib/libgnuradio-iio.so...: undefined symbol: _ZN5boost6chrono12steady_clock3nowEv

During handling of the above exception, another exception occurred:

Here is the MAKEPKG File: Can you help?

Hi,

if you replace the source line with source=("git+https://github.com/analogdevicesinc/gr-iio.git#branch=upgrade-3.8") everything should works fine (see https://github.com/analogdevicesinc/gr-iio/pull/57 )

I've managed to get it to build against gnuradio 3.8, with the PGKBUILD and patch that you can find here: https://gist.github.com/DonOregano/d45b84163fad7e9568befbc047b37c26

However, I cannot get it to work in gnuradio. I get the following error from GR: thread[thread-per-block[0]: <block fmcomms2_source(3)>]: pmt_to_long: wrong_type : #f

Anyone have any ideas?

Any chance to provide a fix?
