It would be useful to document your efforts on our Wiki at: http://gnuradio.org/trac/wiki/GentooInstall Use account name 'guest', password 'gnuradio'. > The problem I now have, is when I try running any of the examples or usrp > .py scripts I get "ImportError: No module named gnuradio". > > How do I get python to find the gnuradio module? I'm not all that familiar with Gentoo, but three things have to happen post install for USRP applications to work: * The shared library loader needs to be able to find GNU Radio .so files. This may be as easy as re-running ldconfig, or you might have to add something to /etc/ld.so.conf * Python needs to know about the GNU Radio install. The files will get put into $prefix/lib/pythonX.X/site-packages/gnuradio, which is typically already a place Python knows about, but you might have to set PYTHONPATH to include that directory up to but not including the 'gnuradio' part. ($prefix is typically /usr/local) * The USRP device file needs to have permissions altered for someone besides root to be able to write to it. If Gentoo uses udev then there is a configuration directory under /etc you can drop a file into that does this (see the UbuntuInstall wiki page as an example). Typically we create a group called 'usrp', give the device file root.usrp ownership, and 660 permissions. Then just add users to group 'usrp' as needed. > Additionally what scripts can I run to check gnuradio is working without a > USRP attached? The best method is to run the 'make check' command from the top-level source directory. This runs through hundreds of unit tests on various parts of the tree. But you've already done that. In $prefix/share/gnuradio/examples/* you'll see a number of installed example programs. Under 'audio' there is dial_tone.py, a simple tone generator that will test your audio output as well. More complicated are the 'digital' examples. You can run 'benchmark_loopback.py' without a USRP and it will exercise a lot of the tree. Let us know how it works out. -- Johnathan Corgan Corgan Enterprises LLC http://corganenterprises.com _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
