Re: [Discuss-gnuradio] Problem loading Python block

[Nemanja Savic]

I deleted everything that was Gnu Radio-ish and istalled fresh new version. But it doesn't work now. GRC won't start, it complains about environment variable, I checket, they are good.

When I want to start uhd_fft I come the following error:

Traceback (most recent call last):
  File "/usr/local/bin/uhd_fft", line 24, in <module>
    from gnuradio import gr, gru
  File "/usr/local/lib64/python2.6/site-packages/gnuradio/gr/__init__.py", line 27, in <module>
    from gnuradio_core import *
  File "/usr/local/lib64/python2.6/site-packages/gnuradio/gr/gnuradio_core.py", line 23, in <module>
    from gnuradio_core_runtime import *
  File "/usr/local/lib64/python2.6/site-packages/gnuradio/gr/gnuradio_core_runtime.py", line 24, in <module>
    _gnuradio_core_runtime = swig_import_helper()
  File "/usr/local/lib64/python2.6/site-packages/gnuradio/gr/gnuradio_core_runtime.py", line 20, in swig_import_helper
    _mod = imp.load_module('_gnuradio_core_runtime', fp, pathname, description)
ImportError: libgnuradio-core-3.6.4git.so.0.0.0: cannot open shared object fil

The problem is this objest does exist in this location: /usr/local/lib64

I am using RHEL6.

Just install 3.6.3, you should be fine.
Otherwise, manually browse through /usr/local and kill everything that
looks GNU Radio-ish.
