I have installed GRC on Ubuntu 9.04 with GNuradio 3.2.
I make a simple flow graph but the problem is that the tab on pannel (
execute the flow graph is still disable). Is there any problem in
All options in Build are also disable.


You probably have an error in the flow graph: are any blocks or
connections in red? The error message will be in the parameters dialog.

Also, try running some of the examples, i dont know where they get
installed to, but you can download the examples from here as well:


The examples are also found in /usr/local/share/gnuradio/examples/grc
