Yes, This example can work. But when I change the languge from C to c, it not work any more. In example LibraryPort export a fuction 'com_apple_dts_library_IOKitWithLibrary_LibraryFunction', I'm change HelloKernel ---- extern void com_apple_dts_library_IOKitWithLibrary_LibraryFunction(void); kern_return_t HelloKernel_start (kmod_info_t * ki, void * d) { printf("Kext has loaded!\n"); com_apple_dts_library_IOKitWithLibrary_LibraryFunction(); return KERN_SUCCESS; } --- now compile passed, First I load Library.ext first, In my point, Load HelloKernel will work, In fact, it still report unresoved message.
