Re: Bug#317082: libc6-s390x: missing depends on lib64gcc1
BTW, Nikita, dpkg-shlibdeps in dpkg-cross should have additional elf64 entries for ppc64 and amd64 like: @crosslib64formats = (elf64-sparc, elf64-s390, elf64-x86-64, elf64-powerpc); Thank you for mentioning that. I've committed this change. However, before new upload of dpkg-cross, some work should be done to make it consistent with recent dpkg changes. I hope to do that soon, but it will take some time anyway. Nikita pgpiAeeOpJCdJ.pgp Description: PGP signature

Re: Bug#317082: libc6-s390x: missing depends on lib64gcc1
reassign 317082 dpkg-dev thanks Summary: The bug submitted in #317082 that requests adding Depends: lib64gcc1 to libc6-s390x on s390. However the bug submitted in #258647 that requests removing Depends: lib64gcc1 to libc6-sparc64 on sparc. Both bugs are conflicted because both libc6-s390x and libc6-sparc64 packages are equivalent as 64bit libc6 biarch package. I decided to remove Depends: lib64gcc1 from libc6 which explains below. This bug should be fixed as dpkg-dev's dpkg-shlibdeps handles 64 bit libraries like dpkg-cross' dpkg-shlibdeps does. Debian sparc and s390 people, from glibc 2.3.5-2 and until dpkg-shlibdeps supports 64bit libraries correctly, when you install biarch 64 bit binary packages, you may have some problems: installed binaries can't resolve 64bit libraries. In that case, please install such libraries packages manually.

We do not want to unconditionally depend on the non-default biarch packages. dh_shlibdeps doesn't work for 64bit packages, so you have to hand-code all the dependencies ... maybe dpkg-shlibdeps could use objdump -x instead of ldd to determine the needed library dependencies? I tested this problem on sparc64, dpkg-shlibdeps detects lib64gcc1 - even if libc6 does not depend on it. The actual concern suggested by Matthias was: dpkg-shlibdeps can't resolve 64 bit libraries when the built environment uses 32 bit kernel. The current dpkg-shlibdeps detects dependent libraries using ldd and objdump. However /bin/ldd 64bit-binaries can't work on 32bit kernel (it's the correct behavior). objdump -p can't show the actual path because elf binary has library names, but not library pathnames. And dpkg-shlibdeps can't work for 64bit binaries on 32bit environment. The current libc6-sparc64 in sarge has Depends: lib64gcc1. However this kind of manual assignment for debian/control file is a bad way. Why is it bad? Because in future we probably have more biarch applications (ex: imagine multimedia gnome application that handles over 4GB video data, and it has a lot of library dependencies), so manual handling should be dropped. I removed this dependency from glibc 2.3.5-2 in experimental. The correct fix discussed and suggested by Ryan, Daniel and Matthias was: dpkg-shlibdeps should handle 64bit library dependencies even on 32 bit kernels correctly. Actually dpkg-shlibsdeps in dpkg-cross package should have worked nicely because it considers about 64bit libraries. BTW, Nikita, dpkg-shlibdeps in dpkg-cross should have additional elf64 entries for ppc64 and amd64 like: @crosslib64formats = (elf64-sparc, elf64-s390, elf64-x86-64, elf64-powerpc); Regards, -- gotom -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

I tested this problem on sparc64, dpkg-shlibdeps detects lib64gcc1 -
even if libc6 does not depend on it. BTW, during this issue, I found
the following problem on s390x:
