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: image-x86-64-20140505110100.iso: seek error - 8: Invalid argument Replace fseek with fseeko to fix this issue.

Hello all, Past few days I was working on porting the isohybrid perl script to c. (-> https://fedorahosted.org/fedora-engineering-services/ticket/15) The first patch towards the same is attached with this mail. And the same could also be accessed from: http://pjp.dgplug.org/tools/syslinux-3.86-isohybrid.patch I would really appreciate it if somebody could have a look at it and let me know

Dear list, I have been trying to debug a build failure for a while in the utils directory on isohybrid which seems to be distro specific. On Fedora 17 64bit the build completes without problems, but under both Ubuntu 32/64bit 11.10 and 12.04 I get the following: tim at oxygen:/usr/src/git/syslinux/utils$ make gcc -O2 -luuid -o isohybrid isohybrid.o isohdpfx.o isohybrid.o: In function

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,

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.

Hi, at [Tails] we're in the process of shipping hybrid ISO images by default again. We're using `isohybrid -h 255 -s 63' to do that (thanks to the advice we got on this mailing-list a few months ago!). And then, we've discovered that sometimes, isohybrid produces ISO images whose size is not a multiple of 2048 bytes. Who cares? ... may you ask. Well, apparently, VirtualBox does:

Hi, > All the "isohybrid.exe" I know of are based on the Perl variant. I just got one from http://www.filewatcher.com/m/isohybrid.exe.39568-0.html Its strings seem not to stem from isohybrid.pl. Digging in slitaz source brought a shell script (that would be variant #5 then): http://hg.slitaz.org/wok/file/313b384e2a06/syslinux/stuff/tools/isohybrid.sh But isohybrid.exe must

One advantage of the Perl one for me

The relation of both is: isohybrid.in/.pl is being left behind. http://git.kernel.org/cgit/boot/syslinux/syslinux.git/tree/utils/Makefile has: SCRIPT_TARGETS += isohybrid.pl # about to be obsoleted isohybrid.c replaces it feature-wise and adds new features. Only those new features contain the bugs,

How to express the embarrassing fact that ISOLINUX is not ready for UEFI but isohybrid is ? http://www.syslinux.org/wiki/index.php/Isohybrid#UEFI would
