I am trying to to dynamically change hier block
content and connections.
Let me explain with a minimal example below.
Why the method delete_path does not want to work?
Thanks a lot for

Hi Marcus,
No, I'm not referring to the category. I'm talking about
the file group ownership.
I would like that the generated python
scripts had the same user/group owner of the grc file opened in GRC.
Thanks for help.

Hello guys!
I am searching for a GRC option such that the group
name of the generated python scripts is automatically set.
I do not
know if this option is already available, but i would like the generated
python scripts belong to the same group name of the relative grc file.
Thanks for help.

Thanks for answering.

I'm trying to implement a sync block into a OOT module

The problem is that when I use

I'm sorry for late.
Setting correct paths in [grc]
section of ~/.gnuradio/config.conf works for seeing the blocks into the
block tree.
The problem now is that when I launch GRC from gnome shell

Hi Volker!
In order to see the local blocks in GRC, I also set
$GRC_BLOCKS_PATH.
Based on your suggestions, at the moment I added the
following variable definitions in .bashrc:

My aim is to setup a workstation with GNU Radio and a

Hello everybody!
I have just found out the "Single Pole IIR Filter"

complex pole.
Is there a specific reason? Which is the best way to
realize this functionality without exploiting the more complex "IIR
Filter"?

I'm trying to implement a python custom (general) block

your flags solved the specific error.
The error on

Dear all,
I'm compiling GNU Radio 3.8 for E310 using the newer file
system and SDK.
Cmake runs smoothly, but when I compile I can see
mainly two errors:
- stdlib.h not found: this is impossible, because I
can find it in the sysroot of the SDK.
