Quick fix for the warning “Clock skew detected. Your build may be incomplete.”
When compiling my Linxu Kernel in my Ubuntu VM, I sometimes bump into the following warning:
Clock skew detected. Your build may be incomplete.
Solution
Searching on the Internet, all but one solution helps solve the problem (source):
find . -type f | xargs -n 5 touch make clean make
Root Cause
A good explanation has been given here. Quote:
“That message is usually an indication that some of your files have modification times later than the current system time. Since make decides which files to compile when performing an incremental build by checking if a source files has been modified more recently than its object file, this situation can cause unnecessary files to be built, or worse, necessary files to not be built.” — source
