Installing gnuradio e110

GNU Radio
1

Hello, i’m new in gnuradio and i want to update all needed to program
this
device the e110.

how it says in:
http://code.ettus.com/redmine/ettus/projects/usrpe1xx/wiki/FAQ#How-do-I-install-GNU-Radio-from-source
i have downloaded the latest image e1xx-003 and store to sd with the
MakeEttusSDCard.legacy.sh.(the MakeEttusSDCard.sh didn´t work for me).
i updated the uhd and then the FPGA firmaware following all instructions
and
everything OK.

but the problem is when i want to update the gnuradio,if i run:

opkg remove --force-depends gnuradio gnuradio-dev gnuradio-examples
task-gnuradio
git clone gnuradio.git - GNU Radio gnuradio.git

cd gnuradio.git

mkdir build

cd build

cmake -DCMAKE_INSTALL_PREFIX=/usr

-DCMAKE_TOOLCHAIN_FILE=…/cmake/Toolchains…

make

i have this error:

[ 13%] Built target pygen_gnuradio_runtime_python_gnuradio_gru_21325

some idea?.
looks like there is some syntax error in the code downloaded but is not
possible.

thanks.

best regards,
Julian.

Hi Julian,

I’ve looked at that syntax error and it was fixed about two weeks ago,
When did you do your git clone?

Greetings,
Marcus

Hello Philip, thanks for the help but i found another problem with this
and
didn´t find any solution on the web.

i´m trying to create the swap file folowing this instrucctions i found
here(i´m not sure if they are correct):
http://elinux.org/BeagleBoardUbuntu#Creating_a_Swapfile

root@usrp-e1xx:~# sudo mkdir -p /var/cache/swap/
root@usrp-e1xx:~# sudo dd if=/dev/zero of=/var/cache/swap/swapfile bs=1M
count=128 (for a extrange reason i can not create more than a 244MB file
having more than 1GB of freee space).
128+0 records in
128+0 records out
134217728 bytes (134 MB) copied, 0.808868 s, 166 MB/s
root@usrp-e1xx:~# sudo chmod 0600 /var/cache/swap/swapfile
root@usrp-e1xx:~# sudo mkswap /var/cache/swap/swapfile
Setting up swapspace version 1, size = 131068 KiB
no label, UUID=7921823e-1a0e-423d-bd8f-af5aef73efbe
root@usrp-e1xx:~# sudo swapon /var/cache/swap/swapfile
swapon: /var/cache/swap/swapfile: swapon failed: Invalid argument

also i have tried updating the file /etc/fstab including this line at
the
end:
/var/cache/swap/swapfile none swap sw 0 0

and then running it with but i got the same:
root@usrp-e1xx:~# swapon -av
swapon on /var/volatile/cache/swap/swapfile
swapon: /var/volatile/cache/swap/swapfile: found swap signature: version
1,
page-size 4, same byte order
swapon: /var/volatile/cache/swap/swapfile: pagesize=4096,
swapsize=134217728, devsize=134217728
swapon: /var/volatile/cache/swap/swapfile: swapon failed: Invalid
argument

any idea?

thanks again.

best regards,
Julian.

Add a swap file. That file needs a bunch of RAM to build.
