wxGUI libraries in the GRC

I am using the USRP N210 and running the same application as described
in the ettus website/youtube:
“How To Build an FM Receiver with the USRP in Less Than 10 Minutes”

I noticed in my GRC I don’t see some of the blocks that they have used
in the video, such as WX GUI Text box, WX GUI FFT Sink,
WX_GUI_notebook. I am using GNU Radio Companion 3.7.2.1.

I have attached a snapshot, showing all the blocks that are available
to generate a flowgraph. Please let me know how to enable the blocks
that are not available currently in my GRC.
I am using windows 7 64 bit OS.

Hi Anusha,

Sorry, I can’t open Word files; and that’s not only me on this mailing
list. From a security point of view, I wouldn’t do that either with
any word file that was sent to me. If you have a picture, please
upload that to any of the many image hosters (imgur.com or something
of the like) and use a link to that page in your mail.

Anyway, did you look into the “instrumentation” menu? Does using the
search functionality (the magnifier glass icon) yield any results for
wx?

Greetings,
Marcus

PS: It just takes some time for us to process the mails that pass

next time :wink:

Correction: Finally, my LibreOffice managed to open the file.

What you’ve posted is a screenshot of putty, an SSH client and
terminal emulator for Windows, where you’ve logged in to a remote
computer “circe” (most probably a linux system) and try to start gterm
(a terminal emulator itself) there.
That being a graphical program and you being only connected by a text
terminal makes the program unable to launch.

However, this has nothing to do with GNU Radio. You need a working GNU
Radio installation on a computer you have graphical access to in order
to use the GRC (GNU Radio Companion), which is a graphical user
interface.

Since you do mention a version number, I guess you have installed
GNU Radio somewhere, most probably your own Windows PC. In that case,
you will find GNU Radio there.

If there is a GNU Radio installation on circe.jpl.nasa.gov, you can’t
use the graphical user interface.

Greetings,
Marcus

Sorry for reposting. I wanted to make sure the group received my post as
I just registered today.
I have searched for wxGUI library and individual blocks that I needed
for this demo as shown on the youtube . I did not find anything with
“wx” in the GNU software blocks.

About the attachment, I just realized I have attached an incorrect one.
In the above attached document(2 page) you will see all the available
libraries that I have access and can play around. I have uploaded the
image @imgur.com as well.

Perfect, can you look into the “instrumentation” category? On a fully
fledged GR installation, there are two subcategories “QT” and “WX”,
though your windows installation might lack one. You can use the QT
FFT sink instead of the WX one, and use the QT entry box instead of
the wx text box, if that is not available.

Sorry for the confusion,

Greetings (and good night),
Marcus

I just noticed I don’t have QT FFT sink

Also can you please suggest what OS is recommended to have my USRP up
and running without any glitches. If Linux is recommended I don’t mind
getting a linux system and what kind of system do I need(memory,
storage??)
Thanks

Dear Anusha,

In my experience, it will be easy to install GNU Radio if you use:

  • Ubuntu 12.04 LTS (either 32bit or 64bit)
  • minimum 2GB of RAM
  • 10GB harddisk space is more than enough
  • install using “build-gnuradio” script at
    http://www.sbrac.org/files/build-gnuradio
  • if you use USRP networked series (eg. N210), make sure your PC has
    gigabit ethernet port
    (Fast ethernet does not work if you connect USRP N210 directly to your
    PC)

Regards,

Thank you.
I don’t have" WX" and have only “QT” Library under Instrumentation.
Maybe that’s a windows issue?

As you have suggested I will replace “WX” blocks with “QT” blocks.

Thanks for your help,
Anusha

But you do have a “QT GUI Frequency Sink.” Same thing.

Hi Anusha,

The Windows binaries for GRC version 3.7.2.1 do not have WX GUI stuff.
You
have to install an earlier version of GRC.

Please see:
https://lists.gnu.org/archive/html/discuss-gnuradio/2013-12/msg00497.html
for
a discussion on this and how to install a working version under Windows.
