ok after more testing...

this problem is here when i use mfcuk 0.3.5, 0.3.7, 0.3.8, 
with libnfc 1.7.0, rc6, rc7

it will compile but still gives the warning;

mfcuk.c:248:17: warning: ‘mfcuk_verify_key_block’ defined but not used 
[-Wunused-function]
 static uint32_t mfcuk_verify_key_block(nfc_device *pnd, uint32_t uiUID, uint64_t ui64Key, mifare_key_type bKeyType, uint8_t bTagType, uint32_t uiBlock)
                 ^
it wont crack any keys with the -R args even when the key is added with -d 
with -s 250 -S 250 olso no luck

it will verify the key with -V 0:A:FFFFFFFFFFFF so this is working only the 
cracking part wont work 
how can this be fixed....??????
