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

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

just forgetting a little thing....you can also don't put any paths in
your .bashrc, "sudo ldconfig" will take care of all the necessary stuff.
If you use "paths" you have to logout and then to login again so the OS
is aware of them (every time you add a new one to .bashrc). if you
decide to use checkinstall, after installation edit the configuration file.
/etc/checkinstallrc
and put the "TRANSLATE" entry from 1 to 0.
Best Regards, Arturo
