Hello,

That error was fixed a long time ago, so I must ask you to submit more details of which board and build you encountered this error on.

On http://android.git.linaro.org/gitweb?p=platform/external/powertop.git there is a branch named "linaro", and that branch is used in all our Android builds. Please make sure that this is the one you use.

BR, Tony
