Re: [Discuss-gnuradio] gr-uhd swig troubles

[Josh Blum]

Whats your swig version? The last time I encountered this, someone had
swig 2 and it was incorrectly parsing an enum to type 'str' (rather than
int). Whats this print?

python -c "from gnuradio import uhd; print
type(uhd.io_type.COMPLEX_FLOAT32)"
