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", line 43, in <module>

    from gnuradio_core import *

  File "/usr/local/lib/python2.6/dist-packages/gnuradio/gr/gnuradio_core.py", line 23, in <module>

    from gnuradio_core_runtime import *

  File "/usr/local/lib/python2.6/dist-packages/gnuradio/gr/gnuradio_core_runtime.py", line 24, in <module>

    _gnuradio_core_runtime = swig_import_helper()

  File "/usr/local/lib/python2.6/dist-packages/gnuradio/gr/gnuradio_core_runtime.py", line 20, in swig_import_helper

    _mod = imp.load_module('_gnuradio_core_runtime', fp, pathname, description)

ImportError: /usr/local/lib/libgnuradio-core-3.4.0git.so.0: undefined symbol: _ZTIN5gruel12msg_accepterE

Any advice?

From today's GIT, fresh build

./bootstrap
./configure
make
sudo make install

Then when I try to use gnuradio stuff:

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.
