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):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python2.6/dist-packages/gnuradio/gr/__init__.py",

Any advice?
