If you are trying to crack a big rar file with rarcrack (Mine was 2.6G) and you’re receiving this error:

$ ./rarcrack --type rar ./file.rar
 RarCrack! 0.2 by David Zoltan Kedves (kedazo@gmail.com)

 ERROR: The specified file (./file.rar) is not exists or
 you don't have a right permissions!

You need to add these lines below in rarcrack.c and recompile. (Put them before #include rarcrack.h )

#define _FILE_OFFSET_BITS 64
#define __USE_LARGEFILE

While you’re there you can fix the error message’s English 😉 I leave it to you to find it. 😉
