[USRP-users] GNU Radio can't detect USRP 1

[Kehinde Ogunyanda]

I followed the instruction on this link to install GNU radio package on my
Ubuntu 12.04:
http://gnuradio.org/redmine/projects/gnuradio/wiki/UbuntuInstall

I have been able to do some online examples with GRC, but sometimes along
the examples the GRC window closes abprutly, and whatever recent changes I
might have made used to varnish, only God knows what the problem is.

Also, I don't seem to find any directory like this on my machine:
gnuradio-examples/python/usrp

In fact, there is nothing like gnuradio-folder any where on the machine.

The main problem that prompted me to poste this question is that, GNU does
not recognise the USRP 1 I connected to the system, and I don't really know
what the problem is. The command provided in the link above, for testing if
the device is recognised or not, did not work for me, since i do not have
the example folder. I tried to manually download the “usrp_benchmark_usb.py”
file, but when I issue the command, “./usrp_benchmark_usb.py” from the
directory where I saved it, I get the following error:

bash: ./usrp_benchmark_usb.py: Permission denied

I have tiredlessly sought for solutions online, but to avail. Kindly help
solve these problems. The following are the details that appear from my
terminal, each time I load the GRC, they might help you in finding speedy
response to my problems.

Hi,

I'd highly recommend uninstalling all GNU Radio and UHD Ubuntu package
files and running the build-gnuradio script which Marcus Leech has been
working hard to perfect:

http://gnuradio.org/redmine/projects/gnuradio/wiki/InstallingGR#Using-the-build-gnuradio-script

As of yesterday the above script installs GNU Radio Companion along with
GNU Radio 3.6.5 and UHD_003.005.003 by default and installs flawlessly on
Ubuntu 12.04 LTS x64. You need to paste and run the following line:

wget http://www.sbrac.org/files/build-gnuradio && chmod a+x
./build-gnuradio && ./build-gnuradio -ja -v

For you to then update to GNU Radio 3.7, goto the 'gnuradio/build' folder
and run the following in order:

sudo make uninstall
rm -rf ../../gnuradio/build/*
git checkout master
cmake ../
make -j4 (4 = number of cpu cores you have)
sudo make install
sudo ldconfig

Regarding your 'Permission Denied' error, in Linux you need to do a 'chmod
+x' to make it executable and run it as root with the 'sudo' command if you
do not have USB permissions. Marcus' build-gnuradio script above sets up
these USB permissions for you automatically.

Regards,

Mike
