Gr-fosphor with pybombs

Hey folks,
So i installed the gr-fosphor ‘app’ using the pybombs recipe and it
seems
to install ok, but when i run it I get the output listed below. Any
ideas
here?

Thanks,

Hi,

ImportError: cannot import name fosphor

Does /home/cnlsdr1/pybombs/lib/python2.7/dist-packages/gnuradio/fosphor
exist ?

Cheers,

Sylvain

sorry for the late reply, was away from this lab. no that directory dose
not exist

thanks,

Interesting …

Are you sure you haven’t two install of pybombs with different
prefixes that would mix things up ?

If not, I think pybombs keeps a build log somewhere for the various
installed package, try to find it and pastebin it somewhere.

Cheers,

Sylvain

Sylvain,
Firstly, there is only one install of pybombs on this machine, so
definitely no separate install conflicts

Second, unfortunately, in an effort to start over, i uninstalled
gr-fosphor
and attemted to reinstall it. I’m now getting this opencl error now. not
sure if this was something i overlooked last time, but i thought the
build
was ok.
the resources on the internet regarding opencl are somewhat hazy (or at
least they are to me) and it seems that there are many different options
for drivers. Can you shed some light on building these with pybombs as a
dependency for gr-fosphor? Should they be installed system-wide or do
they
have to be installed in the pybombs environment?

thanks,
-b

Can you shed some light on building these with pybombs as a
dependency for gr-fosphor? Should they be installed system-wide or do they
have to be installed in the pybombs environment?

The whole OpenCL SDK (headers / libs / drivers) must be installed
outside of pybombs, at the system level and before you try to build
gr-fosphor.

See the OpenCL notes on https://sdr.osmocom.org/trac/wiki/fosphor

Cheers,

Sylvain

My particular video card OpenCL drivers moved where they were installed
between different
versions of Ubuntu. I tracked it down with:

~$ locate libOpenCL.so

  producing...

/usr/lib/i386-linux-gnu/libOpenCL.so.1
/usr/lib/i386-linux-gnu/libOpenCL.so.1.0
/usr/lib/i386-linux-gnu/libOpenCL.so.1.0.0
/usr/lib/x86_64-linux-gnu/libOpenCL.so
/usr/lib/x86_64-linux-gnu/libOpenCL.so.1
/usr/lib/x86_64-linux-gnu/libOpenCL.so.1.0
/usr/lib/x86_64-linux-gnu/libOpenCL.so.1.0.0

So when building gr-fosphor:

cmake …/ -DOPENCL_LIBRARY=/usr/lib/x86_64-linux-gnu/libOpenCL.so

– Tom, N5EG

ok, no progress, but here’s what i’ve done so far. (all as per the
https://sdr.osmocom.org/trac/wiki/fosphor instructions)

sudo apt-get install cmake xorg-dev libglu1-mesa-dev

git clone https://github.com/glfw/glfw
cd glfw
mkdir build
cd build
cmake …/ -DBUILD_SHARED_LIBS=true
make
sudo make install
sudo ldconfig

then, sudo apt-get install opencl-headers

Next, because i have an intel integrated graphics controller in my
laptop i
chose the “Intel CPU OpenCL” option from the instructions
i went to the link on the page, but it says that there is no standalone
OpenCL SDK package anymore and that you have to download the “Intel Code
Builder for OpenCL” so i downloaded and installed this:

https://software.intel.com/en-us/articles/intel-code-builder-for-opencl-api

after that, (from my pybombs directory) i ran ./pybombs install
gr-fosphor
which returns an ‘ok’ message at the end of the install.
I now run osmocom get this for my output:

http://pastebin.com/SpWJKwBc

I now run osmocom get this for my output:

http://pastebin.com/SpWJKwBc

Pastebin :

  • A full listing of all the files in your pybomb install (using find)
  • The complete build logs of gr-fosphor (and no, I have no idea where
    to find those, I never used pybombs, but it must put them somewhere)

Cheers,

 Sylvain

I appreciate the response. Before you wrote back I wanted to try a fresh
install because i wanted to confirm 100% that there were no conflicting
packages outside my pybombs environment. After i deleted my main pybombs
directory i tried to reinstall pybombs, uhd and gnuradio, but now
gnuradio
won’t even install, so i’m going to have to hold off on fosphor until i
can
get that issue fixed.

i’ve reached out to the discussion board in a new thread for help with
those issues.

thanks for your help so far

Actually if you read everything they say it’s still available for linux
:

https://software.intel.com/en-us/articles/opencl-drivers#ubuntu64

reinstalling ubuntu from a fresh build and installing the intel opencl
sdk
from the link above worked out really well. i finally got osmocom_fft -F
to
work and its beautiful!

thanks for the support!
