Folks at CoreAudio,
I am trying to compile the SampleUSBAudioPlugin for MAC, which went fine.
I also tried setting up my kernel debugger and was able to break into the traget.
I am able to see the driver loaded using showallkmods on the host machine.
However I am unable to create a symbol file for the kernel extension on the host machine.
When I try doing this on my host machine
| sudo kextutil -s <Location of kext and kext.dSYM> -n -arch i386 -k /Volumes/KernelDebugKit/mach_kernel -e -r /Volumes/KernelDebugKit <location of my kext> |
I get the following error message:
IOAudioFamily.kext - no dependency found for com.apple.kext.OSvKernDSPLib.
IOAudioFamily.kext - no dependency found for com.apple.kext.OSvKernDSPLib.
/tmp/SampleUSBAudioPlugin.kext has problems:
Dependency Resolution Failures:
Indirect dependencies can't be resolved:
com.apple.iokit.IOAudioFamily
com.apple.driver.AppleUSBAudio
I tried doing the following to have the resolution removed:

But creating the symbol file still doesn't work.
I am beginning to wonder if this is the right Sample I need to be working with in the first place.
I am working with a USB Audio Headset and trying to get a kext working with it.
The idea is to add functionality to the kext and get things going.
What am I missing here and is there something wonrg in the way I am approaching the fix.
Anybody have any ideas?
