I just followed the build instructions for GnuRadio 3.3.0 on
Ubuntu 10.04 LTS. All the dependencies updated/installed without
trouble, and the
sudo make install
worked fine. However, trying to run gnuradio-compainion failed, and
produced a misleading suggestion to check the PYTHONPATH environment
The real solution was to run “sudo ldconfig”. After this, everytning
ran without problems.
Perhaps the 10.04 build instructions should be updated.
In any event, it would seem that the “make install” target should
include running ldconfig at the end.
