Subject: [gentoo-dev] Multilib no-emul-linux-x86 profile testing request

1 Hello, amd64 users.
3 As you know, we were working on a better multilib support in Gentoo for
4 a long time. Finally, we believe that most of the outraging issues were
5 fixed and we'd like to request a wide testing of our new, shiny tool.
7 For your convenience, we have created a mirror of standard amd64 Linux
8 profiles in no-emul-linux-x86 flavor:
10 [9] default/linux/amd64/13.0/no-emul-linux-x86
11 [10] default/linux/amd64/13.0/no-emul-linux-x86/desktop
12 [11] default/linux/amd64/13.0/no-emul-linux-x86/desktop/gnome
13 [12] default/linux/amd64/13.0/no-emul-linux-x86/desktop/gnome/systemd
14 [13] default/linux/amd64/13.0/no-emul-linux-x86/desktop/kde
15 [14] default/linux/amd64/13.0/no-emul-linux-x86/desktop/kde/systemd
16 [15] default/linux/amd64/13.0/no-emul-linux-x86/developer
17 [16] default/linux/amd64/13.0/no-emul-linux-x86/selinux
19 Those profiles mask all app-emulation/emul-linux-x86-* packages
20 and some other unsupported configurations, therefore helping Portage
21 make your system full gx86-multilib. Please test them well since
22 eventually they will be merged onto the regular profiles, along with
23 emul-linux-x86 packages being last rited for removal.
25 The profiles are mostly intended for ~amd64 users. Stable amd64 users
26 have to expect some keywording issues that we are in the process of
27 resolving [1]. It is also recommended to use the newest Portage version
28 available since Zac is improving the dependency resolver every day.
30 There are two strategies for migrating existing systems:
32 1. You can set ABI_X86="32 64" in your make.conf to enable multilib
33 build in all installed packages that support it. This is the easy way
34 but it also means that you're going to build a lot of unneeded 32-bit
35 libraries.
37 2. You can enable abi_x86_32 as-needed. This involves some extra effort
38 but you get only what you need (well, not exactly but close enough).
39 Portage's --autounmask helps a lot here, but you may need to upgrade
40 Portage for better suggestions :).
42 Please enjoy testing and let us know of your experience (e.g. by
43 replying to this mail on gentoo-dev@).
