Hi everyone , I installed gnuradio by binaries provided by Ettus Research in ubuntu software centre. Everything installed properly and I got gnuradio-companion but whenever I run flowgraph I get these warnings Warning: Block key "blocks_ctrlport_monitor_performance" not found when loading category tree. Warning: Block key "blocks_ctrlport_monitor_performance" not found when loading category tree and Using Volk machine: sse4_2_32 Volk warning: no arch found, returning generic impl I'm using ubuntu 12.04 i3 64bit processor. I'm not getting any waveforms in WX-GUI scope sink . When I run the flowgraph using WX-GUI scope sink all I can see is a simple lines varying up and down. Can somebody help me !!! Thanks in advance Sandhya

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, these are warnings, and you won't be able to use ctrlport.monitor_performance, but this is not a problem as is. The Volk warning is just telling you that it's falling back to a safe implementation, which could be slower in some cases, but will surely work. To explicitely say it: a warning is a warning that things *might* go wrong. It is not an error. In most cases, one should not heed it too much, unless it seems to be related to the problem at hand. I think you're seeing a single line jumping up and down, and that is what your data looks like to the wxgui sink. Try using a larger value for t/s, the < > buttons on the upper button row on the very left. Also make sure you're not clogging your CPU with work. If you don't have a hardware device setting the the sample rate (e.g. a USRP, a sound card) in your flowgraph, consider simulating that using a throttle block.

Thanks marcus . well all these days I was using live usb where I was getting different (eg sine wave ) kind of output when I was using WX-GUI scope sink so I thought it would be missing some package so I wasn't able to see that output . well thanks ...

*well i'm running into new problem using constellation block .* File "/home/sandhya/top_block.py", line 16, in <module> from gnuradio.wxgui import constsink_gl File "/usr/lib/python2.7/dist-packages/gnuradio/wxgui/constsink_gl.py", line 25, in <module> import const_window File "/usr/lib/python2.7/dist-packages/gnuradio/wxgui/const_window.py", line 25, in <module> import plotter File "/usr/lib/python2.7/dist-packages/gnuradio/wxgui/plotter/__init__.py", line 22, in <module> from channel_plotter import channel_plotter File "/usr/lib/python2.7/dist-packages/gnuradio/wxgui/plotter/channel_plotter.py", line 23, in <module> from grid_plotter_base import grid_plotter_base File "/usr/lib/python2.7/dist-packages/gnuradio/wxgui/plotter/grid_plotter_base.py", line 24, in <module> from OpenGL import GL File "/usr/lib/pymodules/python2.7/OpenGL/GL/__init__.py", line 11, in <module> from OpenGL.GL.VERSION.GL_1_2 import * ImportError: No module named VERSION.GL_1_2 Checking out the previous thread I found two solutions "First, you can probably install python-opengl on your system. Or you can turn of GL support by editing the file in (probably) /usr/local/etc/gnuradio/conf.d/gr-wxgui.conf and change the 'style = auto' option to 'style = nongl" But either of the two solutions are working and throwing me the same error. Anyone can help me on this Thanks Sandhya
