Hi,

> Why 3.10.4.0 and not the latest 3.10 (currently is 3.10.5.1)?

I am porting modules from 3.7 to 3.10 and when I started porting, 3.10.4.0 was the newest version. 

> How did you install gnuradio previously and how did you uninstall it? Make sure you don't have two gnuradio versions installed in parallel - one from deb/apt packages in /usr and a second one from source in /usr/local.

I uninstalled it as given on the GRC-wiki: "sudo apt remove gnuradio"

I did install debug symbols after installing from source, sould i maybe try install debug symbols before installation?

Does it help if I give the code of the according block? I am really running out of ideas here...

Thank you so much for you help until here 😊

Best,

How did you install gnuradio previously and how did you uninstall it? Make sure you don't have two gnuradio versions installed in parallel - one from deb/apt packages in /usr and a second one from source in /usr/local.

Why 3.10.4.0 and not the latest 3.10 (currently is 3.10.5.1)?

What is the phy_header's type? Is it a function or class?

How did you install the debug symbols? Before or after installing from source?

We don't need python debug symbols as this segfault is not in the python and we are not going to debug the python executable.

That's strange. Is this with gnuradio installed from source?
