Q:
When using kmodload, why do I get a "Can't find superclass" error?
A: You may see an error similar to Listing 1 if your KEXT uses
classes from other I/O Kit families.
kmodload: Can't find superclass for _13AppleUSBMouse : _12IOHIPointing
| |
Listing 1. kmodload error
|
This error can be eliminated by specifying your dependencies using the
-d option. For example...
kmodload -o AppleUSBMouse.sym -d IOHIDSystem.kext/Contents/MacOS/IOHIDSystem
|
If you depend on more than one I/O Kit family, use multiple -d
arguments, one for each family. Remember, you should only use kmodload
when creating symbol files for use with 2-machine debugging. Otherwise,
use kextload.
