I am trying to install RTAI 5.0.1 on Ubuntu 18.04 LTS in Linux Kernel 4.1.18. I was following this tutorial. But unfortunately I am stuck in this part
make -j `getconf _NPROCESSORS_ONLN` deb-pkg LOCALVERSION=-rtai
The error is:
make: *** No rule to make target 'deb-pkg'. Stop.
What should be the target?
