Hi, everyone,
When I ran a python program, I met such a question, can you holp me to point
out where the problem is?
The problem is as follows:
Traceback (most recent call last):
File "MainFrame.py", line 106, in OnDBPSK_Demodulate
objDemod = DBPSKDemod.dbpsk_demod(fg)
File "/home/cwang/prj/ufl/source_code/Receiver/DBPSKDemod.py", line 153, in
__init__
gr.hier_block2.__init__(self, self._fg, self.pre_scaler, self.unpack)
#changed from block to block2, cwang 9.29
File "/usr/local/lib/python2.6/dist-packages/gnuradio/gr/hier_block2.py",
line 42, in __init__
self._hb = hier_block2_swig(name, input_signature, output_signature)
File
"/usr/local/lib/python2.6/dist-packages/gnuradio/gr/gnuradio_swig_py_runtime.py",
line 1015, in hier_block2_swig
return _gnuradio_swig_py_runtime.hier_block2_swig(*args, **kwargs)
TypeError: in method 'hier_block2_swig', argument 1 of type 'std::string const'
Thanks.
Cheng
