After the update the last sdrpp in Ubuntu (22.04. yesterday) the tetra decoder crashes with following error Message:

the crash comes after enabling the plugin and after start sdrpp with active sdrpp-tetra-demodulator in the plugin conf.

I hope we can solve this issue, i need the plugin :)

thanks in advance

I've just encountered this issue as well after installing the latest sdrpp version. I have a gdb backtrace for the crash. Possibly the ABI has changed.

Edit: I found the commit. There has been an ABI change, indeed. The module needs to be recompiled against new core library.

Edit 2: It's not possible to recompile the plugin due to changes in CMake build system, which cause linker errors...
