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,

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

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 [Making sure you're not a bot!](https://sdr.osmocom.org/trac/wiki/fosphor)

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

</div>

ok, no progress, but here’s what i’ve done so far. (all as per the  
[Fosphor - SDR (Software Defined Radio) - Open Source Mobile Communications](https://sdr.osmocom.org/trac/wiki/fosphor) instructions)

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

git clone [GitHub - glfw/glfw: A multi-platform library for OpenGL, OpenGL ES, Vulkan, window and input](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:

> **[Intel® SDK for OpenCL™ Applications](https://www.intel.com/content/www/us/en/developer/tools/opencl-sdk/overview.html)**
>
> Write portable code for client PCs, servers, and embedded systems that use multicore CPUs, GPUs, FPGAs, and parallel processors and coprocessors.

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:

> **[osmocom\_fft -F output - Pastebin.com](https://pastebin.com/SpWJKwBc)**
>
> Pastebin.com is the number one paste tool since 2002. Pastebin is a website where you can store text online for a set period of time.

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,

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
