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

[Beckmann, Niklas]

Hi Vasil,

I have two blocks in the module, where I use "digital". Which source code do you need exactly, the .h file in the include folder, the _impl.cc file from the lib folder,

or the _impl.h file from the lib folder (or all of them?) ? I could provide anything that "helps to help" .

Best,

N

But unfortunately this backtrace is not very useful because you are missing debug symbols. How to install debug symbols largely depends on how you installed gnuradio and the distribution that you are using. For Ubuntu you can get some info here https://wiki.ubuntu.com/Debug%20Symbol%20Packages

Also it looks like the crash is in gnuradio's digital. Can you share the part of source code where you are using it?
