GnuRadio gr-iio build

radiohead
on Dec 10, 2019

Hi all,

I'm trying to build gr-iio but it breaks on the unavailability of some gnu radio source files

Using this procedure:

git clone github.com/.../gr-iio.git
cd gr-iio
cmake ..
make

fatal error: gnuradio/analog/sig_source_f.h: No such file or directory
#include <gnuradio/analog/sig_source_f.h>
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
lib/CMakeFiles/gnuradio-iio.dir/build.make:337: recipe for target 'lib/CMakeFiles/gnuradio-iio.dir/iio_math_impl.cc.o' failed
make[2]: *** [lib/CMakeFiles/gnuradio-iio.dir/iio_math_impl.cc.o] Error 1
CMakeFiles/Makefile2:135: recipe for target 'lib/CMakeFiles/gnuradio-iio.dir/all' failed
make[1]: *** [lib/CMakeFiles/gnuradio-iio.dir/all] Error 2
Makefile:129: recipe for target 'all' failed
make: *** [all] Error 2

I built gnuradio 3.8.0 following the recipe below (running on Ubuntu Bionic 18.04 with python3 installed).

https://wiki.gnuradio.org/index.php/InstallingGR#From_Source

Gnuradio stand alone works, libiio works fine, python bindings also.

I presume gnuradio needs to install the include files to be able to build gr-iio correctly. Is there a quick fix?

Thanks

    Are you able to locate the file by doing the following:

    $locate sig_source_f.h

    GNU Radio 3.8 requires a specific branch: https://github.com/analogdevicesinc/gr-iio/tree/upgrade-3.8

    Wow Travis, you nailed it again. gr-iio can be built and installed.

    However, gnu-radio now complains that the iio module has no attribute pluto_source.

    Could this be related to the rollback of libiio you recommended me to do on a previous ticket last friday?

    In GR-3.8 we had to put the gr-iio module in a different place, so sometimes the bindings interfere since they have the same module name (iio). I would remove the bindings iio.py file.

    Then we get some other errors from gnuradio. Sorry but I'm lost here.
