I'm writing my first KEXT. When i launch it, i've this problem: The code is: #include <sys/systm.h> #include <mach/mach_types.h> #include <mach/mach_host.h> #include <mach/host_info.h> #include <kern/kern_types.h> #include <kern/host.h> kern_return_t host_info_start(kmod_info_t *ki, void *d) { host_basic_info_t info; mach_msg_type_number_t count = HOST_BASIC_INFO_COUNT; kern_return_t ret; printf("KEXT has loaded!\n"); kern_return_t host_info_stop(kmod_info_t *ki, void *d) { printf("KEXT will be unloaded\n"); return (KERN_SUCCESS); } Can you help me, please?
