All,
I think I am having a version problem. I followed the instructions from the
gnuradio and UHD Start page.
I download gnuradio using
$ git clone git://gnuradio.org/gnuradio
git branch --track next origin/next
git checkout next
And then I do the usual
./bootstrap
./configure
make
make check
sudo make install
sudo ldconfig
Everything goes fine and everything that I expect to get installed does, but
then as soon as I try to run something it breaks, see errors below. I dug
further, and I think I have a version problem. Both the version.sh file in
my gnuradio directory and the gnuradio-core.pc file in
/usr/local/lib/pkgconfig say the version in 3.4. But when I run ./configure
it says the version is 3.3.1. As far as I know version 3.4 doesn't exist
yet. I have uninstalled and deleted everything and reinstalled and the
problem remains the same.
Anybody what the problem is?
TIA
Scott

I get the following problem when trying to run any gnuradio programs.
And when I try gnuradio-companion a gui pops up that says "can't import
gnuradio, are your PYTHONPATH and LD_LIBRARY_PATH set correctly?

Yes, that was typo.
PYTHONPATH=/usr/local/lib/python2.6/dist-packages
I did mean dist-pakages. I have three directories in dist, gnuradio
grc_gnuradio usrpm. And nothing in the site-packages.

Thanks Josh. Getting the newest gnuradio from git solved the uhd
problem,
but now gnuradio is broken. I know it must be some path problem but I
have
tried the usual tricks: I set my
PYTHONPATH=/usr/local/lib/pkgconfig/dist-packages and
LD_LIBRARY_PATH=/usr/local/lib and I did sudo ldconfig in the gnuradio
directory. And I checked /etc/ld.so.conf and /usr/local/lib is in there.
Maybe just a typo, but instead of
PYTHONPATH=/usr/local/lib/pkgconfig/dist-packages
try:
PYTHONPATH=/usr/local/lib/python2.6/site-packages
