Problem with Fm receiver code when implemented with cygwin

Hello,
I am new to GNU radio. I installed the software successfully on
cygwin, and I tried to run the FM receiver code (both with GUI and
without
GUI). I got the following errors.-

$ python usrp_wfm_rcv_nogui.py -f 101.9M
Using RX d’board A: Flex 2400 Rx MIMO B

gr_fir_ccf: using SSE
gr_fir_fff: using SSE
Traceback (most recent call last):

audio_sink)

return _gnuradio_swig_py_runtime.gr_top_block_sptr_connect(*args)
NotImplementedError: Wrong number of arguments for overloaded function
‘gr_top_b
lock_sptr_connect’.
Possible C/C++ prototypes are:
connect(boost::shared_ptr< gr_top_block > *,gr_basic_block_sptr)
connect(boost::shared_ptr< gr_top_block >
*,gr_basic_block_sptr,int,gr_basic
_block_sptr,int)

swig/python detected a memory leak of type ‘gr_basic_block_sptr *’, no
destructo
r found.

Could someone please tell me what this error means, and how I get around
it?
Thanks.

Prasanna.

Hello,
Thank you. I didn’t realize that the boards are not capable of
receiving
the waves. Other than that were you able to figure out what rest of the
error messages meant. Because the error messages seem to suggest, that
there
is a problem in the code. I could be wrong though. If you were able to
figure out what the rest of the error messages meant, kindly let me
know.
Thanks.

Prasanna.

I’m still parsing through the rest of the error message, but these
first two lines show that you are trying to receive at 101.9 MHz with
a daughterboard that doesn’t cover that range. There may or may not
be an additional problem, but you’ll never get it working with the
above. You need to use a TVRX or BasicRX board.

I’m not able to replicate your issue here, but I don’t have the Cygwin
environment set up for test. However, the issue appears to be SWIG
related, perhaps an incompatible version issue.
