I don't think this is a Python block since he's linking against ITPP, but
it's not specified in his original question, so I can't be sure.
Anyways, I just tried making a Python block in an OOT project and it works
just fine.
$ gr_modtool nm
Name of the new module: testpy
Creating out-of-tree module in ./gr-testpy... Done.
Use 'gr_modtool add' to add a new block to this currently empty module.
$ cd gr-testpy
$ gr_modtool add
GNU Radio module name identified: testpy
('sink', 'source', 'sync', 'decimator', 'interpolator', 'general',
'tagged_stream', 'hier', 'noblock')
Enter block type: sync
Language (python/cpp): python
Language: Python
Enter name of block/code (without module name prefix): test01
Block/code identifier: test01
Enter valid argument list, including default arguments:
Add Python QA code? [Y/n]
Adding file 'python/test01.py'...
Adding file 'python/qa_test01.py'...
Editing python/CMakeLists.txt...
Adding file 'grc/testpy_test01.xml'...
Editing grc/CMakeLists.txt...
<edited the test01.py file and set it to use float input and float output>
$ mkdir build; cd build
$ cmake -DCMAKE_INSTALL_PREFIX=/opt/gr ../
$ make
$ make install
$ ipython
In [1]: import testpy
In [2]: dir(testpy)
Out[2]:
['__builtins__',
'__doc__',
'__file__',
'__name__',
'__package__',
'__path__',
'test01']
In [3]: a = testpy.test01()
Worked fine. You're not the only person with this problem, but no one has
yet shown me how to reproduce the error.
