Yes, the CMakefile contained an error, the upgrade was twofold, the mothandling is brought inline with that of qt-dab and the handler for the sdrplay is modified since library 2.13 is slightly incompatible with the previous versions. I just ran a quick test - right now I am somewhat limited since I am not at home - but I do not have a problem. It would be helpful if you could run uding gdb and if there is a segmentation fault show thestacktrace Since tonight I am hoe again, I will have a closer look tomorrow 2018-07-22 12:31 GMT+02:00 Bart Peeters <[email protected]>:

First of all thanks for this great repository, I have a SDRPLAY and have been using it to play DAB+ using this repo. I have been testing using code based on the example-3. I see that you've been busy upgrading the library to a newer version. This seems to have broken example-3. The CMakeLists.txt of example-3 has a reference to a file that is renamed: https://github.com/JvanKatwijk/dab-cmdline/blob/ master/example-3/CMakeLists.txt#L336 I changed this to ../library/src/backend/data/mot/mot-handler.cpp and it compiles again. When I run the example it gets to the point where it dab_service(a radio station), but there is no data written to stdout and sometimes I also get a segmentation fault. Any help would be appreciated. — You are receiving this because you are subscribed to this thread.

That's the segfault I get. Sometimes it does run and outputs, sometimes it runs but doesn't output and other times I get the segfault.

Thanks, it turned out that there was an initialization error somewhere. The error showed up with
DAB rather than DAB+ programs. This one seems fixed
