python3
from PyQt5.QtWidgets import *

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

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:
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 ?

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
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
