Bug 534432 – net-fs/samba-4*: multilib support

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Michał Górny 2015-01-03 13:54:23 UTC]

A boilerplate bug to block unmasking of samba-4* until it gets proper multilib support. So far, it would be good to figure out if the client libs can live without 32-bit python.

[Comment 1 Andrei Slavoiu 2015-03-10 20:25:05 UTC]

Apparently this bug failed and samba 4 got unmasked even without proper multilib support. Now I get:

!!! Multiple package instances within a single package slot have been pulled
!!! into the dependency graph, resulting in a slot conflict:

net-fs/samba:0

  (net-fs/samba-4.1.17:0/0::gentoo, ebuild scheduled for merge) pulled in by

+1 here.

[Comment 3 Dennis Schridde 2015-04-24 08:47:38 UTC]

This also blocks bug #490872 via the abi_x86_32 requirement of e.g. ffmpeg.

Was any progress made recently? Can someone please add the bug-dependency I mentioned?

Sorry, wrong bug. Again.

[Comment 6 Stijn Tintel 2015-07-04 15:00:48 UTC]

For those with the slot conflict, I too had this problem.

In make.conf I have:

ABI_X86="64 32"

To work around the conflict, I created /etc/portage/package.use/abi_x86_32:

gnome-base/gnome-vfs            -abi_x86_32
media-plugins/gst-plugins-libav -abi_x86_32
media-video/ffmpeg              -abi_x86_32
virtual/ffmpeg                  -abi_x86_32

Then you can do "emerge -1 media-plugins/gst-plugins-libav media-video/ffmpeg net-fs/samba virtual/ffmpeg".

(Add gnome-vfs only if you have it installed).

Multilib is working on samba-4.2.7-r1 and samba-4.3.4

[Comment 8 Víctor Ostorga (RETIRED) 2016-02-07 20:20:13 UTC]

Multilib is working on samba-4.2.8 and samba-4.3.4-r1

> Multilib is working on samba-4.2.8 and samba-4.3.4-r1

I'm not so sure. Two version of samba compiled with 'abi_x86_32' (result of gnome-base/gnome-vfs abi_x86_32). Always in abi_x86_32.x86/ linking with 64bit libraries! Only solution was remove 'abi_x86_32' so no multilib!

So most of that is normal. What isn't normal is that you're missing the libs in /usr/lib32/ that it's looking for, and as such it is -only- finding the incompatible 64bit versions.  And the only reason or way that this would occur is if you're using a rather messed up portage configuration for how abi_x86_32 packages are installed.

I know many of you do this, but the ABI_X86 use-expand is *not* actually meant to be set globally.  You should allow --autounmask-write to handle setting abi_x86_32 on each of the packages that need it, instead.  Yes it amounts to a fairly large package.use file, but it also keeps you from installing a slew of 32bit packages that don't need to be there.

You're probably right, but I can't find any specific reason for such behaviour.
All three libs, for which linker thrown error - libcom_err.so.2, libz.so.1 and libattr.so.1 are present in /usr/lib32 directory and 'ldconfig -XNv' reported them, so there is no reason why linker can't find them. All packages with abi_x86_32 are exclusively listed in one file '/etc/portage/package.use/multilib', so I have no idea how it can be messed in the first place.
