Re: [Discuss-gnuradio] repeat variable in a file source

Hi Linda20071 - The error shows that either your Python code isn't passed a 'bool' type, or the SWIG interface isn't providing the correct API for Python. Without seeing your code it's pretty difficult to tell. So if you have a public repo please post it along with your query. There are plenty of examples in both GR and OOT modules that do the boolean interface from C++ to Python via SWIG. Hope this is useful. - MLD

We use "repeat" variable in a file source to show whether or not we want to repeatedly play the file. In my module, I generated a limited length of random data, and I use "bool repeat" to show whether or not I want the limited length of data to be repeatedly played. However, when I run the module, I got a type error message that complains the bool type of this "repeat" variable in the make function as shown below:

  File "/usr/local/lib/python2.7/dist-packages/mysource/mysource_swig.py", line 154, in make

    return _mysource_swig.mysource_make(len, repeat, upsampling_rate)

TypeError: in method 'mysource_make', argument 2 of type 'bool'

However, as I understand, the "repeat" needs to be declared as "bool". Is there a fix for this problem?
