Description Alex W. Jackson 2006-10-27 03:49:58 EDT
Description of problem:
The x86_64 build of unshield is completely broken and unusable.  It always
reports an MD5 checksum failure for every single file in every cabinet you
attempt to extract or test.

Version-Release number of selected component (if applicable):

How reproducible:
Attempt to extract or test any InstallShield cabinet using unshield

Actual results:
unshield will report an MD5 checksum failure for every single file in the
cabinet, and fail to extract the files

Expected results:
MD5 checksum failures should only occur if the cabinet is actually damaged

Additional info:
Googling for "unshield md5", I came across this:


Note the commit dated 2006-10-18.  Apparently, unshield contains its own
implementation of md5 which is not 64-bit-clean code.  The OpenBSD package
maintainer fixed the issue by making unshield use the system md5 (OpenBSD has
md5 in their libc) instead of its own implementation.  We don't have that
luxury, so it looks like we'll have to actually fix unshield's md5 (or rip it
out and replace it with the one from coreutils, but I don't think they're
license compatible)

PATCH: fixing md5 sum code on 64 bit


Since I've gotten quite good in fixing 64 bit bugs I've taken a quick look
at this. Fixing it turns out to be rather trivial, take a look at the attached

If you're short on time I can drop this and an updated spec in CVS and requests
builds if you want me to.

thanks for helping out with this :) pushed for fe-{3,4,5,6} and devel :)
Comment 4 Hans de Goede 2006-11-17 11:31:18 EST

1) Don't forget to also send this upstream, so that other distros can pick this 
   up eventually.

2) Offtopic, have you received my scummvm-tools mail? Is it ok for me to update
   it to the latest and submit to FE, or do you want todo that?
