Dear Sebastian

I downloaded and installed the release taken from the web page (in .zip 
format).

https://github.com/awvwgk/dftbplus/tree/xtb-transport

Unfortunately, when I feed the executable with the Au-Chain input 
(modified for using the xtb hamiltonian) I still get the error given 
from the main branch:

-> Eigensolver incompatible with transport calculation (GreensFunction 
or TransportOnly required)

Is there a flag to add to the cmake command line?

Best Regards.
Luca
