Hi,
We recently bought a new PC with some powerful specs. GNU Radio was
built from the source and it seems to be installed fine. However, when
I try to use the virtual sink and source blocks in my flow graph, I am
getting the following error:
Traceback (most recent call last):
File "./test_skh.py", line 595, in <module>
tb = test_skh()
File "./test_skh.py", line 486, in __init__
self.connect((self.virtual_source_0, 0),
(self.blocks_multiply_conjugate_cc_0, 0))
File
"/usr/local/lib/python2.7/dist-packages/gnuradio/gr/hier_block2.py",
line 93, in __getattr__
return getattr(self._impl, name)
*AttributeError: 'top_block_sptr' object has no attribute
'virtual_source_0'*
Once I replace the virtual blocks with direct connections, things work
just fine. What is the cause for this problem and how to fix it?
Please note that on an older machine, GNU Radio was installed around
a month ago following the same procedure followed here, and the
virtual sink/source blocks work just fine.
Thank you.
Best regards,
Khalid

My guess is that this machine has GR installed from the official repos
as well, and you're getting an old GR instance.
