My goal is to rework DBPSK module, so that it is possible to easily implement
SDPSK module.
DBPSK goes like this: differential_encoding > ordinary BPSK, so there is no
actual constellation rotation. All rotation part is done by diff.encoder.
But this can be done only when shifting between 2 state
after successful installation without any errors, when launched in grc gives
this:
Traceback (most recent call last):
File "/home/thunderbolt/top_block.py", line 12, in

from howto_swig import *
Thank you! That solves my problem )
Seems it was because I had modified gr-howto-write-a-block-3.3.0 package
with my own block installed on top of original gr-howto-write-a-block-3.3.0
package, without uninstalling it.

This block should take a bit from chunk, and produce an output (d_phase)
which would hold until next chunk comes in. Right now it does take chunk,
extract this bit, produce correct phase, but next moment block output drops
to 0+0j.
It gives me feeling that block is producing output all the time,
Reworked it to derive from gr_sync_block. Seems to work. Now I only have to
test it somehow, and write a hier.block something like:
packed_to_unpacked->diff_const->rrc_filter, and probably SDPSK should work.
Thank you Eric !

Now, after reading "how to write a signal processing block" i can write and
properly install c++ signal blocks. But I also need to install few python
hierarchical blocks and their *.xml's along with these c++ blocks.
How do I include them to that gr-howto-write-a-block-3.3.0 package, so that

While playing with DQPSK I have encountered a problem:
Scheme: File_source -> DQPSK_mod -> DQPSK_demod -> File_sink
Parameters:
samp_rate = 500
DQPSK_mod/demod samples per symbol = 215
DQPSK_mod/demod gray code = no
everything else - by default
Input bit sequence:

Minimal "samples/symbol" is 2.
Is there a maximal ?

Somehow managed to install git and get gnuradio source. Now I have a problem
with source installation. "sudo ./configure" says:
The following components were skipped either because you asked not
to build them or they didn't pass configuration checks:
gruel
gcell
gnuradio-core
usrp
usrp2

I do have it.
log repeatedly says:

So I guess it's confdefs.h )) You have any idea what is it?
I googled it. Seems to be a common problem, but I still cant find a normal
solution or e
Thanks! I've started to understand this a bit.
Now it's like this:
gcell
gr-gcell
gr-audio-jack
gr-audio-osx
gr-audio-portaudio
gr-audio-windows
gr-comedi
gr-video-sdl
grc
These components will not be built.
I wonder if I need gcell and gr-gcell.
Definitely need grc.
Here is a log

Am I correct, thinking that gnuradio should work on any platform, as long as
it's on ubuntu?
Will I be able to run it on http://beagleboard.org/ Beagleboard with

Hi!
I know that Gnuradio script is able to write data to console when running
(some output data). I haven't tried anything, but it should be able somehow,
because blocks can be written in c++, and c++ program is able to write in
terminal window.
If say, I connect to other computer via COM port (u

I have problems with gr-ais installation on my Beagleboard running Ubuntu
Lucid.
./configure wants gnuradio-core package
Searched with aptitude, and it seems threre is no such package for ARM EABI
Ubuntu distribution. Gnuradio was installed without problems and seem to
work as usual. What to do?
n as I can. Probably then someone could help me with this.

I'm trying to get gr-ais working on Beagleboard running Lucid.
Here is a screenshot from serial terminal:

Says can't find gnuradio-core. As far as I understood, it might be possible
that gnuradio-core is installed somewhere, and I just have to
I've searched for libgnuradio-core.so with find / -iname
"libgnuradio-core.so" and found nothing.
But there are libgnuradio-core.so.0 and libgnuradio-core.so.0.0.0 at
/usr/lib/
Aren't they the same with libgnuradio-core.so?
How do I set PKG_CONFIG_PATH?
Do I rewrite this block in configure:
I just don't get it.
Here is a file which contains both - ./configure output and config.log:
http://old.nabble.com/file/p30103724/configure_and_log.txt
configure_and_log.txt
And this is configure file itself:

Also gnuradio-core.pc is missing some why. Maybe that's the problem?
