..... -D_FILE_OFFSET_BITS=64 ... Thus above message and patch of Kai Kang should be considered. (The patch looks ok to me.) Other occurences of fseek() might cause problems too. Each change to fseeko() has to be checked, whether the type of the offset argument is indeed off_t. Example: uint32_t catoffset = 0; ... if (fseek(fp, catoffset * 2048, SEEK_SET)) The call has to become something like if (fseeko(fp, ((off_t) catoffset) * 2048, SEEK_SET)) Adresses which are surely smaller than 31 bit could be left unchanged. E.g.: if (fseek(fp, 17 * 2048, SEEK_SET)) Kai Kang's cha...

Hi, following will be 6 patch proposals for isohybrid.c 1: Encode GPT partition names as UTF-16LE 2: Correct blocking factor in APM partition block counts 3: Correct end block address of first GPT partition 4: Write GPT backup to the very end of the image 5: Change all fseek(3) to fseeko(3) 6: Introduce option --mbr and make isohybrid.c compilable standalone If the form needs adjustments,
