Re: [Discuss-gnuradio] SWIG std::vector issue

Anyone able to help with this?  I had to create helper methods to serialize the PMT objects and return a vector of strings.  Not the best solution :(

I have a utility lib in C++ created with 'gr_modtool add noblock' that has a function that returns a vector of pmt::pmt_t values.  I need to then be able to access the elements of that vector via Python.  Right now I get the following error when using a for loop to iterate over the vector:

TypeError: 'SwigPyObject' object is not iterable

swig/python detected a memory leak of type 'std::vector< boost::intrusive_ptr< pmt::pmt_base >,std::allocator< boost::intrusive_ptr< pmt::pmt_base > > > *', no destructor found.

How does one iterate over the elements of a std::vector<pmt::pmt_t> in Python?

Thanks!
