...; in the help text of isohybrid.c. It should be "APM". ---------------------------------------------------------------- Known Variants up to now: - isohybrid.in -> isohybrid.pl from SYSLINUX, no EFI/GPT support - isohybrid.c -> isohybrid from SYSLINUX - libisofs/make_isohybrid_mbr.c from libburnia, needs isohdp[fp]x*.bin -> libisofs, xorriso from SYSLINUX - isohybrid.sh from SliTaz, no EFI/GPT support - iso2exe.c -> isohybrid.exe from SliTaz, no EFI/GPT support ---------------------------------------...

Hi, hpa: > The right thing to do is compile it with #define _FILE_OFFSET_BITS 64 > and change fseek to fseeko with the appropriate type being off_t. And for GPT names it should really use 16-bit UTF-16LE characters and not 8-bit characters padded up by the same number of random bytes from the program memory. See e.g.:

I'll file a ticket once fedorahosted is back online. The request is to port the isohybrid script, in the syslinux package, from perl to C (and of course submit it upstream). This would let syslinux drop its dependency on perl, which would save considerable space. $ wc -l git/syslinux/utils/isohybrid.in 258 git/syslinux/utils/isohybrid.in As this is doing some simple structure unpacking

When call isohybrid with option '-u', it overflows on a 32 bits host. It seeks to 512 bytes before the end of the image to install gpt header. If the size of image is larger than LONG_MAX, it overflows fseek() and cause error: isohybrid: wrlinux-image-x86-64-20140505110100.iso: seek error - 8: Invalid argument Check the offset and call fseek() multi-times if offset is too large.
