[Discuss-gnuradio] benchmark_tx.py gives error

[Shravan Rayanchu]

Hi all,

I get an error (TypeError: unpack non-sequence) when I run
benchmark_tx.py with the option "bitrate". (I also get the same error
when using -i for interpolation). It runs fine when these options are
not specified. I am using the latest gnuradio version from SVN and
swig 1.3.31, python 2.4.2 with ubuntu. (./configure told me that
ezdop, alsa did not build .. hope thats not a problem)

I have an older version of gnuradio (on a different machine) which
uses an older swig and these examples run fine. Is it a problem with
the new version of gnuradio/swig?

Here are the details:

$ ./benchmark_tx.py -f 2412M

RUNS FINE.

$ ./benchmark_tx.py -f 2412M --bitrate=500k -v

Traceback (most recent call last):
