AW: AW: AW: AW: Import Error "undefined symbol"

[Beckmann, Niklas]

Hi Vasil & Phillipp,

I just un- and reinstalled gnuradio from source (basically following the steps at the wiki)... that did not solve the problem.

Im on version 3.10.4.0 and im on Ubuntu 20.04. 

@Phillipp you were right, gnuradio does not crash if I open another flowgraph. The import I was originally aiming to do works now.

And i found when gnuradio segfaults: it happens when I add a variable block with 

"mymodule.phy_header().formatter()"

(maybe that additional info is useful)

@Vasil I did install the debug symbols, but when I do the command,
it still shows 

Reading symbols from python...

(No debugging symbols found in python)

And the rest of the output is still the same...so I dont know what wrong here. That indicates that the installation of the debug symbols went wrong?

Thank you very much for your help so far, I would be very thankful for any further help 😊

Best,

N

The _impl.{h,cc} files as the .h file most likely does not contain anything that's important for this crash.

Install the gnuradio's debug symbols and then take another backtrace.

How did you install gnuradio, which version and which Linux distribution?
