Psk implementation problem


#1

Hi,

I am attaching a screenshot of PSK implementation.
But when i run the flowgraph i am confronted with the following error

Executing: “/home/harshal/test8.grc.xml”

Verbose:
Traceback (most recent call last):
File “/usr/share/grc/src/ExecFlowGraphGUI.py”, line 231, in OnInit
self.SetTopWindow(FlowGraphFrame(self.flow_graph_file_path))#first
argument is the flow graph

return _gnuradio_swig_py_gengen.vector_source_b(*args)
NotImplementedError: Wrong number of arguments for overloaded function
‘vector_source_b’.
Possible C/C++ prototypes are:
gr_make_vector_source_b(std::vector< unsigned char,std::allocator<
unsigned char > > const &,bool)
gr_make_vector_source_b(std::vector< unsigned char,std::allocator<
unsigned char > > const &)

Done

Am i missing something obvious?

Hi Harshal,

You are using a very old version of GRC (0.70?). Because this version
does not come with gnuradio, there are guaranteed compatibility issues.
These issues will not be fixed.

Install a version of gnuradio that comes with GRC (either gnuradio
trunk, or 3.2 release branch). That way, GRC is guaranteed to work with
your gnuradio install.

If you have trouble installing gnuradio trunk, or 3.2 release branch,
contact this mailing-list.
