Comment 3 Scott Garman 2012-06-13 04:25:30 UTC 
Hi Sun,

The only way I could see this occurring is if the runqemu scripts (specifically oe-find-native-sysroot) is unable to run bitbake. The directory you invoked this in when you ran into the problem, ~/work-dir/poky-contrib/test, was this your build directory?
Comment 4 Richard Purdie 2012-06-18 22:07:35 UTC 
Please provide more information and reopen if this hasn't been fixed...
