If you're working with a lineage tree, you might encounter errors related to livedisplay, touch, and hidl. To resolve these, edit the common.mk file located in device/manufacturer/something-common. Remove the lines referring to touch, hidl, and livedisplay, then restart the build.
This usually means that your machine ran out of ram. The -j option in the make command specifies the number of jobs (commands) that make can run simultaneously. Restart the build with for example
make bacon -j[NumberOfJobs] <- without brackets!!!
Then your build should go as planned.
