Re: [Discuss-gnuradio] UHD error: _ZN3uhd6device4findERKNS_13device_addr_tENS0_15device_filter_tE

Hi Zamrath,

now you're mixing different versions of the same library (UHD).
The debian GNU Radio was built and linked against the debian UHD, but now you're using the Ettus UHD package, so the symbols that the debian GNU Radio thought it knew are now unavailable.
You should uninstall debian's UHD version, when installing the Ettus one. You also must uninstall debian's GNU Radio.

You will have to build GNU Radio against the UHD library version you're using. You *can* in theory, do that on the bananapi itself, but I don't think that is going to be fun (or short) -- after all, it's an embedded device, and not a development workstation, so CPU and RAM are sparse.
There are three ways you can go from here: (1) build GNU Radio on the bananapi, (2) cross-compile it for the debian armhf port and (3) rolling out openembedded and treating your bananapi as a cool embedded device rather than a boring slow PC.

Method (1)
=======
This should be the easiest path: use pyBOMBS, as it should do everything for you[0], and take roughly veeeeeery long.

Method (2)
=======

I think that in the long run, if you want to do software development for the bananapi, anyway, setting up a cross-compilation environment will be what you want to do.
However, I'm not really used to doing cross-builds myself; I can only outline what you will have to do:

On your (easiest case: debian) workstation:

* Install the appropriate cross toolchain[2], and all the libraries[1] lists as necessary in their development version and target-arch (armhf) compatible version. I think that will be the hardest part, as it's a bit debian specific.
* Follow [3] . Replace the oe-sdk-toolchain.cmake file with a debian/armhf one -- you can have a look at the existing arm toolchain file[4], copy and modify it, replacing all compiler names with their gcc-armhf-... or similar pendants. Trick: use your currently installed "gnuradio-config-info --cflags" to get appropriate CMAKE_CXX_FLAGS, in addition to the right -m*** flags, that might be omitted in the output.

Method (3)
=======

Alternativile, follow [5] and replace the debian on your bananapi with an openembedded self-rolled system.
OpenEmbedded allows you to deploy your own application-specific system, including everything from OS to application (but not much more).

No matter what you do, we'd like to hear of your success (and/or struggle). If you generate any useful build script / toolchain files / tips and tricks / blog posts ... we'd love to hear of them!

Greetings,
Marcus

Hi all, 

I have recently installed UHD and GNURadio on Bananapi (armhf) board adding  "deb http://ftp.de.debian.org/debian jessie main" in "/etc/apt/sources.list".

Downloaded GNURadio from "https://packages.debian.org/jessie/armhf/gnuradio/download"

dpkg -i gnuradio_3.7.5-5_armhf.deb

apt-get update

Downloaded UHD from "https://packages.debian.org/wheezy/armhf/uhd-host/download"

dpkg -i uhd-host_3.4.2-1_armhf.deb

apt-get -f install

When I install OpenBTS, built was errored since UHD was not picked up. (uhd.pc was not in "/usr/local/lib/pkgconfig"). 

Therefore, I had to install uhd-master from ettus research git repo and built. And then OpenBTS was built without a problem.

After connecting USRP N210, even though ping process is also okay, 

"uhd_find_devices" gives,

I have erased the memory and proceeded again with caution but the result was same. Could  anyone please suggest me a resolution? 

Thanks.

Best,

Zamrath Nizam
