I got the same error today as Marcus did last week in a fresh install
from next on Ubuntu 10.04 x64. Everything worked fine through the
UHD install, ./bootstrap, ./configure, make, make check, sudo make
install routine. However, attempting to run gnuradio companion reports:
"Cannot import gnuradio. Are your PYTHONPATH and LD_LIBRARY_PATH set
correctly?"
I have the following in my .bashrc file:
# GNU Radio installation
export PATH=$PATH:/usr/local/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python2.6/site-packages
Also, attempting to "from gnuradio import gr" in a python prompt returns:
>>> from gnuradio import gr
Traceback (most recent call last):

Any advice?

Re-did the build a coupla of times, including "make clean" and
"make distclean". Still the same results.
Did a "sudo ldconfig" just in case it was the LD cache. No dice,
still same problem.
System is Ubuntu 10.10 x86_64

pay attention ! on debian based distribution the "local" pythonpath is
*export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python2.6/dist-packages*
not the one you put in the .bashrc ! I compiled the source tarball
(stable 3.3.0) without any problems in this way
sudo apt-get build-dep gnuradio
./configure
make
and then using the "checkinstall" utility
sudo checkinstall (instead of make install)
after the generated *.deb is installed digit :
sudo ldconfig
my hypothesis of the wrong pythonpath could be confirmed by your
errors....Let me know....
The problem exists even with a correct PYTHONPATH. I confirmed this
last week.
