[LITMUS^RT] The feature trace tool error

[shijunjie92]

Hello:

When I try to run the feature trace tool, I got the error 'could not open feathertrace device (/dev/litmus/sched_trace13): No such file or directory'. 
Under the direction from 'http://stackoverflow.com/questions/22993077/litmus-rt-scheduling-traces', I am trying to disable the option 'Build a relocatable kernel'. But in my ubuntu system, this option is locked, which could not been disabled.
'-*- Build a relocatable kernel'. 
So, what should I do?
