DAB transmitter not working with GR 3.8.5?

[nodurah]

Hello,

after successfully compiling the code in the 3.8 branch according to the Readme I still can't get the transmitter part in DABStep to work. After I start the transmitter the program crashes.
The blocks in GNURadio companion examples seem to be not existing as well (and are red in the examples). The receiving path seems to work fine with an USRP X310.

Are there any additional steps to be taken or software to be installed to get the transmitter functionality working? What is the last stable version for 3.8?

Any help would be appreciated.

Cheers
