[Discuss-gnuradio] undefined Symbol with UHD in GRC

[Christian Schroeder]

Hello,

I am just trying to move to UHD. For this I installed the gnuradio 
master branch to a custom location in my home. Moreover, the uhd 
software (release 003.000.001 built from source) is at non-default 
location in /opt/uhd.

./configure, make and make install worked without problems, but when 
running a simple flowgraph in grc using a uhd block, I get an error 
message (see below) when importing uhd.

Maybe I am missing an environment variable at this point?

$LD_LIBRARY_PATH=/opt/uhd/lib/:/home/csc/Software/gnuradio_git_master_2011-03-28/lib/
$PYTHONPATH=/home/csc/Software/gnuradio_git_master_2011-03-28/lib/python2.6/site-packages

A reply from Josh to a similar posting did not point me to the solution. 
 Libraries are there, but I did not find the symbol in 
gr-uhd/uhd_swig.i as mentioned.

OS is Ubuntu karmic 9.10 64Bit.

Any hint is be appreciated.

Kind regards,
Christian
