Re: [Discuss-gnuradio] Where to Start?

[dave]

Well, I have not been able to get GRC to actually run.  I had setup two machines with Ubuntu 11.04 by installing the UHD package from ettus.com.  With that, I have gotten some basic programs to run (dial tone), but typing 'grc' shows the command as not found.

Attempts to install GRC via package first resulted in a version conflict.  A google search suggested I install clean so I did that (installing without the UHD) and instead got a bunch of python errors.  I did all that on the second machine... the first one still has the UHD installation that is not messed with.

Doesn't the GRC come with the UHD package?  If so, where is the binary (or python script) located?  Maybe it will work from the UHD install without any other modifications.

I found the mailing list archive at ruby-forum.com, so I'm checking other threads now.  This is really frustrating!

What you'll find is that you won't need to write your own signal processing blocks, at least, not intially.  GRC (also known as
