Yes. If you are using the UHD sink, it will be the same block for any
USRP device.

Sorry, I don't have time. Keep in mind my earlier suggestion about
matching the sample rates all the way through your flowgraph.

[Discuss-gnuradio] GRC Start Up Frozen

2013-07-19 Thread Matt D 
Hey guys,
On Ubuntu 12.10 yesterday I was compiling some small pieces of code in
terminal for syntax debugging, installing the files, and then testing
functionality in grc.
So the last thing I did was I install what I am working on (op25).  Then
I tried to start the grc but the start got stuck or kind of just froze
after the “boost” thing that came up in the terminal, no error, just
froze.  And after that I noticed some weirdness with filenames
associated with gnuradio. For example I now have file names like
Gr-baz.20130719004000 and rtl-sdr.20130719005437 and there were a couple
of gnuradio folders like that.  So I tried my best to uninstall
gnuradio, I used the uninstall script and manually removed what I could
find in the usr directory. I rebuilt from the 3.6.3.1 source file. In
the rebuild I had to skip the make test because one test (out of 180
tests) failed, I am pretty sure it is was a “volk” something.  Now upon
running the 'sudo gnuradio-companion' the start freezes (not dies) up
with a message box:

“libgnuradio-core-3.6.3.1.so.0.0.0: cannot open shared”

Cannot import gnuradio.

Is the python path environment variable set correctly?
All OS: PYTHONPATH

Is the library path environment variable set correctly?
Linux: LD_LIBRARY_PATH
Windows: PATH
MacOSX: DYLD_LIBRARY_PATH

The pythonpath is set.  I did it myself in the bashrc file.  I don't
know what the library path is. Any guidance on how to get my gnuradio
back will be much appreciated.
Thanks

Re-run build-gnuradio

those "rtl-sdr.YYMMDD" files are the previous instances of the source 
code pulls from git.  The script will clean them up if they're taking up

  too much space.

Once you've re-built everything with build-gnurado, then I'd suggest 
editing your ".grc" file to remove any history of files you might previously

  have been working on, and try again.

[Discuss-gnuradio] wav file source question

2013-07-19 Thread Baokun Liu 
Hi guys,

I am playing with gnuradio companion. I have a question on wav file.

I play like this first (the samp_rate set to 32k)

*Audio Source ---> Wav File Sink;*

I save the file as test.wav. It sound well.

Then, I play the file back (samp_rate is 32k).

*Wave File Source ---> Audio Sink; *

The error comes as: WAV file does not contain any samples.

Could anyone point out the problem? How could I use the 'wav file source'
block?

Thanks,

Baokun

Tweak the firewall rules on your router to allow GIT to pass through.  
Default port is 9418 for GIT.


I can't tell you how to do that on your router.

[Discuss-gnuradio] Gnuradio 3.6.x recipe for pybombs ?

2013-07-19 Thread M Dammer 
Has anyone a recipe for installing the 3.6-branch via pybombs ? I need a
3.6 parallel installation on my system, because many old projects are
not working "out of the box" in 3.7.x. Even many of the projects
referenced by recipes that currently come with pybombs do not compile.
tnx, Mark

Re: [Discuss-gnuradio] wav file source question

2013-07-19 Thread tom sutherland 
I don't know how to post the answer to the discussion group correctly so I just 
sent this to you. I got the same errors. I can write a wav file, I can play the 
wav file using any other audio player but GNUradio "wav source" block gives me 
the same " no samples.." error. I got around this by using the "File Source" 
and "File Save" blocks using *.wav as the names. It seemed to work.

Mark,

You can edit the recipe file to change the branch you want to check
out. In pybombs/recipes/gnuradio.lwr look for the 'gitbranch' line.
Change this from 'master' to the tag of the version you want, such as
'v3.6.5.1' for the latest in the 3.6 version.

It looks like the build_gnuradio script is being used.

Just try the git command that is in the script by itself like this I think:

git clone --verbose http://gnuradio.org/git/gnuradio.git

The command
$sudo ifconfig gr0 192.168.200.1

does not work and return back error of

gr0: ERROR while getting interface flags: No such device

I have tried a number of methods from the linux community but non of them

Does any one in gnuradio community have any clue about it.
