Hello,
I remove all GNURadio and Fosphor packages/libraries on my laptop.
Then I reinstall GNURadio 3.9.
I am now trying to build gr-fosphor following the wiki.
I successfully do the cmake step after installing some dependancies.
But the make step raise this error :
I don't know what to do to solve it ...
For the record, I clone the repository in /usr/share since the wiki
specify "Warning: Mixed prefix install is not supported. You need to
install gr-fosphor in the same prefix as your GNU Radio install." By
doing " dpkg-query -L gnuradio" I obtain a lot of lines starting by
/usr/share/ so I assume that gnuradio were install there.
Hopping you can help me with this new issue 😞
Happy holiday season,
Gwendoline

Gwendoline:
I think you may have conflicting versions of GNURadio and/or Fosphor.
I have had this error before as well.
I use fosphor on a daily basis on both GNURadio 3.8 and 3.9 and I can
confirm that it does work on several different nvidia GPU’s as Sylvain
said. I have had some issues relating to the drivers for the GPU, but
they were usually not related to GNURadio. I also have a machine
without a GPU and am running Fosphor using the Intel CPU
implementation of OpenCL found here:
https://osmocom.org/projects/sdr/wiki/Fosphor#Intel-CPU-OpenCL<https://osmocom.org/projects/sdr/wiki/Fosphor#Intel-CPU-OpenCL>
You should start by uninstalling all previous versions of GNURadio and
Fosphor before continuing. You’ll need to make sure that all libraries
have been removed from your system before trying anything else.
Then, follow the build procedure for GNURadio 3.9 as 3.7 is EOL.
For Ubuntu 20 you’ll also need to make sure your computer is actually
using the NVIDIA driver as it sometimes defaults to the nouveau driver
even if NVIDIA is installed.

Hi,
I install the package but before testing it I see a new problem.
Gnuradio is in version 3.9.4.0.
The fosphor sink block is in error so I can't run the flowgraph.
No matter what Window type I put, I have this error in block
parameters:
Param - Window Type(wintype):
Value "firdes.WIN_BLACKMAN_hARRIS" cannot be evaluated:
type object 'gnuradio.filter.filter_python.firdes' has no
attribute 'WIN_BLACKMAN_hARRIS'
Param - Window Type(wintype):
Expression None is invalid for type 'int'.
Is it because of how I install gr-fosphor ?
Regards,
Gwendoline

Hi,
If you're using Ubuntu, you can try the intel-opencl-icd package which
is the binary package for
https://github.com/intel/compute-runtime<https://github.com/intel/compute-runtime>
which is the OpenCL driver for Intel GPUs.
However, I'm not sure anyone has ever run fosphor with it ... not sure
if it supports the features required, I only tried on AMD and NVidia
GPUs as I don't have any Intel GPU supporting that driver.
Cheers,
Sylvain
