The SPRAWL System needs some additional features that are missing from the main branch of Jacktrip. To build the correct JackTrip version, the Jacktrip git repository must be cloned and checked out to the correct branch.
Therefor git must be installed. On MacOS git is often already installed. Linux users should install git through their package manager. Windows users download the installer from git-scm.
Getting the JackTrip Source Code
Now the JackTrip source code can be downloaded from the official JackTrip repository.
git clone https://github.com/jacktrip/jacktrip.git git checkout nils
Changes in the remote repository have to get pulled.
Afterwards you can follow the official build instructions.
