Hi, Here is a newbie to redhat/fedora multilibs packages, and ideas of elf32/elf64. Originally we only run 32bit RHEL/FC, so multilib support is not a problem for us, but now we have AMD 64bit CPUs and Intel EM64T CPUs, we have to run both 32bit and 64bit Fedora Cores. on 64bit FC4/FC5 we installed 32bit compatibility for legacy programs to run. From that time on headaches appear -- automatical rpm/yum upgrade breaks from time to time, the most often encountered problems are: 1, some times a .x86_64 package can upgrade a same name .i386 package without problems, sometimes the operation fails. 2, when we upgrade a aaa.x86_64 lib package, other .i386 packages depending on the same aaa.i386 lib package will complain and automatic upgrade fails. then we have to upgrade aaa.i386 lib package as well. 3, when upgrade one .i386 package to a same name .x86_64 package, other .i386 packages depending on the original .i386 package will complain and upgrade fails. we have to create a no-files-contained empty .x86_64 package to upgrade all related .i386 pacakges to .x86_64 version. It looks like that 64bit FC4 can not diffrentiate packages ending with .i386 or .x86_64. when the upgrade fails, the error messages are normally like the following: valgrind = 1:2.4.0 is needed by (installed) valgrind-callgrind-0.9.11-1.i386 I assume it should differentiate between "valgrind.i386=1:2.4.0" and "valgrind.x86_64=1:2.4.0" but it does not. I think that is most probably my inaccurate understanding of multilibs, but I can not find detailed info on multilib rpm and elf32/elf64. Please help. Thanks a lot. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
