[Discuss-gnuradio] Re: psk implementation problem

[Josh Blum]

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.
