I run gr-ettus on E300 all the time using the GNU Radio toolchain file.
You have to set UHD_INCLUDE_DIRS and UHD_LIBRARIES, though.

Somewhere we have a toolchain file for cmake to build natively?
Otherwise the default flags are for older arms and no neon.

I didn't realize you were doing on this on the device. If you have all
the PATHs set up correctly, you should be good, but it looks like you're
using the default UHD. Have a look at your CMake cache (in gr-ettus) and
see where the UHD_* vars point to. They're 'advanced' vars, in case you
can't see them immediately.

Martin,
I am not using the SDK. The steps I have taken so far:
Created a new SD card from the dizzy dev image found at [1].
Followed the steps at [2] to clone the RFNoC git repository, switch to
rfnoc-devel branch, build it, install it to /opt/uhd
My next challenge was to install the gr-ettus OOT module to be able to
use the RFNoC blocks in GRC.
The dizzy image already had a previous install of UHD and GNU RADIO.
For RFNoC I installed a new UHD with the RFNoC branch. I was hoping to
add gr-ettus to the existing GNU RADIO install, to simplify things.
I am doing all of this on the E310. Is this the right way to do it? I
assumed that I didn't need the SDK because I already had an SD image
built.
Thanks,

Ben,
you *must* use the right branch of UHD (which I know you've been
using). For cross-compiling, you need to make sure that *all* the
CMake vars starting with UHD_ are correctly set.
Are you using our SDK? If yes, it's probably pointing to the SDK's
default UHD.

Hi,
I'm trying to install gr-ettus on an E310.
I previously installed a new version of UHD (to support RFNoC)
in the
directory /opt/uhd
I would like to install gr-ettus into the existing version of
gnuradio
that is installed.
Inside the build directory of gr-ettus, when I type "cmake ../"
I get
the following message and error:
-- Found UHD: /usr/lib/libuhd.so
CMake Error at CMakeLists.txt:108 (message):
RFNoC not found.
When I had installed UHD, I followed the steps in [1], and
made sure
that the new libuhd.so was in my LD_LIBRARY_PATH and I added
the new
path to /etc/ld.so.conf; however, when I ran ldconfig I got the
following error:
ldconfig: /usr/lib/libstdc++.so.6.0.20-__gdb.py
<http://so.6.0.20-gdb.py> <http://so.6.0.20-gdb.py>
is not an ELF file - it has the wrong magic bytes at the start.
I had ignored that error, partly because I didn't understand
it, and
partly because I had already updated the LD_LIBRARY_PATH
variable. Was
it a mistake to ignore it?
I welcome any advice on installing gnuradio out-of-tree modules
(such as
gr-ettus mentioned in [2]), and advice on managing different
versions of
UHD on the same system. I can't seem to get the gr-ettus
installation
to look at the new version of UHD. Note: I am using the E310
Dizzy
build [3].
Thanks!
