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

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....
