I am trying to follow the example of adding a square_ff module (
https://wiki.gnuradio.org/index.php/OutOfTreeModules). I didn't modify the
python/CMakeList.txt file because it didn't do so in the youtube tutorial (
https://www.youtube.com/watch?v=BW8o9ZgFJ5I). The 'Cmake' and 'make'
command went smoothly. However, when I issued 'make test' in the build
folder, the test failed with an error message "Errors while running CTest:
Makefile:85 recipe for target 'test' failed". I then checked back all the
files, and I found python/CMakeList.txt had been modified automatically
with all the required lines being added. Besides, everything else looks OK
as well.
P.S. 1. Here is the relevant result running 'ctest -V -R square':
Constructing a list of tests
Done constructing a list of tests
Updating test list for fixtures
Added 0 tests to meet fixture requirements
Checking test dependency graph...
Checking test dependency graph end
test 2
Start 2: qa_square_ff
2: Test command: /bin/sh "/home/ubuntu/Documents/GRCFiles/gr-
howto/build/python/qa_square_ff_test.sh"
2: Test timeout computed to be: 9.99988e+06
2: Traceback (most recent call last):

howto/python/qa_square_ff.py", line 24, in <module>
2: import howto_swig as howto
2: ImportError: No module named howto_swig
1/1 Test #2: qa_square_ff .....................***Failed 0.35 sec
2. I tried to make sure 'import howto_swig as howto' in qa_square_ff.py be
in this file by deleting this statement and then adding it
back. However,
I got the following warning:
(gedit:10845): Gtk-WARNING **: 22:47:45.238: Attempting to
read the recently
used resources file at '/home/ubuntu/.local/share/recently-
used.xbel', but the parser
failed: Failed to open file
“/home/ubuntu/.local/share/recently-used.xbel”: Permission denied.
3. If I try to edit the file qa_square_ff from fresh via 'sudo H
gedit qa_square_ff' and save the changes, the following warning occurs:
** (gedit:10790): WARNING **: 22:43:16.086: Set document
metadata failed:
Setting attribute metadata::gedit-spell-language not supported
The OS I am using is Ubuntu18. Any help on solving this problem would be
appreciated!
