I am more than willing to try new message passing interface. The idea with
the thread is a bit old, that's what I have heard, from more experienced
guys. Are there any blocs that uses new message passing interface, so that
I can take a look how it works?

Guys,
As i told you my new installation works fine, I eve tested blocks in
python. Now, the problem is following:
I designed block in python which has None for both input and output
signature. I wanted to use such block only for receiving messages and for
writing to terminal some information, etc

My only guess for that is you have someth
The problem was bad LD_LIBRARY_PATH.
Can anybody explain:
why with LD_LIBRARY_PATH=/usr/bin:usr/local/lib64:usr/local/lib, GRC won't
run, and with LD_LIBRARY_PATH=/usr/local/lib64. it works?

I deleted everything that was Gnu Radio-ish and istalled fresh new version.
But it doesn't work now. GRC won't start, it complains about environment
variable, I checket, they are good.
When I want to start uhd_fft I come the following error:
Traceback (most recent call last):

Just install 3.6.3, you should be fine.
Otherwise, manually browse through /usr/local and kill everything that
looks GNU Radio-ish.

In order to find which version I am using (since I have few build folders
on my computer, and I don't know from which gnuradio was installed, because
i tried a lot of times to install it without success (there were some
problems since I am using RHEL6)) I decided to uninstall everything and

Nemanja,
OK, I'll try to explain everything.
I want to design block responsible for decoding messages, calculating crc,
etc ... In order to do that I investigated packet_demod_base block from
main gnuradio branch,
and also packet_deframer from gr_extras group of blocks. I realized that
such kind of blocks

Guys,
i am not able to load gr.basic_block and make signal processing block in
Python. Simplu, there is no binding within gnuradio/gr for that class.
It works perfectly for gr.hier)block2 class.
What might be the problem?
Thanks

Hi all,
In my first post from today, where I reported error in gr_modtool, I was
using script downloaded from github this morning (just to clarifu how old
scriot I used).
Basically I am trying to make my own packet deframer block, and they are
more or less designed like that. This block was design
- Try the latest gr_modtool from github
- What you're doing seems weird--why are you connecting message blocks?
These are meant as a hackish solution to access samples from outside
the flow graph. Perhaps you want the new PDU to stream blocks?

Since I don't know why gr_modtool doesn't work for me, I took the older
working version and made very simple hier block in order to understand
messages flow in gnuradio.
The block code is following:
from gnuradio import gr
class msg_proba(gr.hier_block2):
def __init__(self, ):
gr.hier
I installed new version of gr_modtool script and it won't work. The error
is following:
[savi_ne@ts-070046nl gr-test]$ gr_modtool.py add -N rx_tx_message -t hier
-l python
Using Python < 2.7 possibly buggy. Ahem. Please send all complaints to
/dev/null.

Thank you Martin, I will try that on Monday.
I suppose that I have older version of gr_modtool, cause there is no option
-l for selecting language.
My weekend would be maybe perfect If you or anybody else can explain to me
why my code won't work, cause I have more or less copied block structure
fr
For a hier block in Python, do
$ gr_modtool.py add -t hier -l python
You need 3.6.3 to do that.
Also, you'll need a new version of modtool (it usually lags a bit behind
changes in GNU Radio).

Hi all,
today i was trying to make hierarchical signal processing block in Python.
I started with gr_modtool script, and configured it for hierpython block
type.
My idea was to design block similar to packet framer, so inside of the new
block, I connected binary slicer and Framer sink. I have als
