xcode - Can't load a kernel extention (.kext file) in OS X (does not contain code for architecture:x86_64 error) -


i trying load kernel extension file (.kext) os x mountain lion (10.8.3). rebuilt xcode 4.6.1. however, when tried load "kextutil -n -t /xxxx.kext", got following warning.

executable not contain code architecture: x86_64

it seems code doesn't support x86_64, did include x86_64 in build settings wherever seems applicable, e.g., valid architectures: i386, x86_64.

how should change settings make loadable 64-bit kernel?

did set "build active architecture only" no mentioned in kernel extension programming topics ("create new project" -> 6)?
