On a related note, you can use the kextlibs(8) tool on Leopard systems
to figure out what your OSBundleLibraries should be.

Hi,
I am trying to use a spinlock in my kext and am having problems
with loading
it. I am calling the initialization functions and using
lck_spin_lock() and
lck_spin_unlock(). Here is the error message:
kextload: resolving dependencies for kernel extensions with
validation and
authentication failures
kextload: extension /System/Library/Extensions/MyKext.kext/ appears

kextload: a link/load error occured for kernel extension

However, I am able to find these symbols when doing the command nm
/mach_kernel | less.
I am also including kernel.frameworks in my project.
Any ideas what's wrong?
Thanks.
