Red Hat Bugzilla – Bug 228171
Last modified: 2007-11-30 17:11:56 EST
hspell - 1.0-4.fc6.i386
File conflict in:
Packages with the same files:
hspell - 1.0-4.fc6.x86_64
The files in /usr/share ought to be arch-independent. Why do they
differ between i386 and x86_64?
*** Bug 228170 has been marked as a duplicate of this bug. ***
I compared the two directories and noticed that the difference is only in one
character per file:
/tmp/h$ hexdump i386/hebrew.wgz|head -1
0000000 8b1f 0008 c96c 44b0 0302 5dcc 9adb baa2
/tmp/h$ hexdump 64/hebrew.wgz|head -1
0000000 8b1f 0008 c981 44b0 0302 5dcc 9adb baa2
both files decompress well in both architectures.
could it be that the gzip produces a different file (different magic number?)
according to its architecture?
P.S. I don't know what multi-lib is, and what is the relevance of this bug's name.
Taking a look at RFC 1952 (GZIP File Format)
http://www.gzip.org/zlib/rfc-gzip.html , I understand that the differing 5th
character is part of the Modification Time of the original file. I suspect that
the reason for the difference is that the two RPMs are packaged in different times:
ls --full-time 64/h i386/h
-rw-r--r-- 1 danken danken 1026227 2007-02-11 09:05:23.000000000 +0200 64/h
-rw-r--r-- 1 danken danken 1026227 2007-02-11 09:05:58.000000000 +0200 i386/h
The file could be compressed with option -n to be the same.

multi-lib is the concept that makes it possible to install libraries
built for a compatible hardware architecture alongside the libraries
for the native hardware, because both can used by corresponding
executables. For example, on x86_64 the native libs are installed
into /usr/lib64, while the compatible ix86 libs are installed into
/usr/lib. That is the reason why %_libdir expands to different values
on these systems. This also makes it possible to build ix86 binaries
on a x86_64 systems, because you only need to tell the compiler which
architecture to build for and install the needed -devel packages for
that architecture. Due to that, ix86 -devel rpms and their dependencies
are made available in the x86_64 repository.
In the context of this ticket, users of x86_64 hardware, who want to
or need to install hspell for i386 (as a dependency of some i386 rpms),
could not have hspell for x86_64 installed already, since both packages
conflict in these data files.
