ok, now i installed ubuntu from scratch on the two laptops not with windows. so is there something missing in this installation : i used this link in synaptic to install gnuradio packages: 11.10 contains 3.2.2.dfsg-1ubuntu7 ( http://packages.ubuntu.com/oneiric/gnuradio) and this guide to install the other packages : http://gnuradio.org/redmine/projects/gnuradio/wiki/UbuntuInstall#Install-Dependencies After successful installation still there is UHD, i installed it through this: git clone git://code.ettus.com/ettus/uhd.git cd uhd/host mkdir build cd build cmake ../ make make test sudo make install #Check where your path is with "find |grep libuhd" export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib i did not do anything else ??
