[gentoo-user] Can I safely switch (no)multilib profile???

[Walter Dnes]

When I installed Gentoo on my desktop PC, I could've sworn that I
selected...

[15] default/linux/amd64/17.1/no-multilib (stable)

...as the profile. ***THINGS HAVE BEEN WORKING FINE FOR A COUPLE OF
YEARS.***

While updating tonight, glibc dies with a build error...

.[31;01m*.[0m ERROR: sys-libs/glibc-2.36-r7::gentoo failed (unpack phase):
.[31;01m*.[0m CONFIG_IA32_EMULATION must be enabled in the kernel to compile
a multilib glibc.

...Digging deeper, I ran "eselect profile list" and got...

[1] default/linux/amd64/17.1 (stable) *

WTF?!? Can I safely eselect profile [15] and emerge update to get
back to normal? Also what could possibly change my profile in the first
place?

Things get curiouser and curiouser. Start with a pretend emerge

=====================================================================
emerge -pv --changed-use --deep --update @world

These are the packages that would be merged, in order:

Calculating dependencies... done!
Dependency resolution took 11.19 s.

[ebuild U ] sys-libs/glibc-2.36-r7:2.2::gentoo [2.36-r5:2.2::gentoo] USE="multiarch (multilib) ssp stack-realign (static-libs) -audit -caps (-cet) -compile-locales (-crypt) (-custom-cflags) -doc -gd -hash-sysv-compat -headers-only -multilib-bootstrap -nscd -perl% -profile (-selinux) -suid -systemd -systemtap -test (-vanilla)" 0 KiB

Total: 1 package (1 upgrade), Size of downloads: 0 KiB
=====================================================================

This says that my current glibc is 2.36-r5 which would be replaced
with 2.36-r7. Now let's try asking for my current glibc version to be
built...

=====================================================================
emerge -pv =sys-libs/glibc-2.36-r5

Note the "(multilib)" in USE. If I remove the "-pv" it too dies early

***I CAN'T EVEN BUILD THE CURRENT GLIBC ON MY MACHINE***. It looks
more and more like somewhere somehow my profile selection got changed
after my previous glibc update.

I regularly back up incrementally to two large standalone backup
drives. Every so often, I tarball my $HOME dir and push the copy over
to my "hot backup" machine. I intend to do that tonight, followed by
selecting profile...

[15] default/linux/amd64/17.1/no-multilib (stable)

...and then running...

emerge --changed-use --deep --update @world

Walter's problems triggered me to check what profile was selected on my
own rig:

# eselect profile show
Current /etc/portage/make.profile symlink:
default/linux/amd64/17.1/desktop
# eselect profile list
!!! Error: Failed to get a list of valid profiles
exiting
#

Anybody having an explanation? What to check?

Any pointers welcome ...

Sincerely,
Rainer

Oops, I didn't know or expect "eselect" to be a Bash script. Otherwise
I would have done this already :-)

I've appended the trace output at the end. This sure revealed the pro-
blem: skimming upward from the call to "die" in line ">196:" one can see
the script trying in line ">>>129:" to extract lines matching "^x86_64"
from "/var/db/repos/gentoo/profiles/profiles.desc". However, there are
none. Skimming farther upward reveals the string "x86_64" being derived
in line ">>>>33:" from environment variable "ARCH" which is defined in
my shell initialization scripts:

export ARCH=$({ arch || uname -m || echo unknown ; } 2> /dev/null)

But the only architectures supported by my "profiles.desc" file are:

$ gawk '! /^#|^$/ { print $1 }
' /var/db/repos/gentoo/profiles/profiles.desc | sort -u
alpha
amd64
amd64-linux
arm
arm-linux
arm64
arm64-linux
arm64-macos
hppa

loong

x64-cygwin
x64-macos
x64-solaris
x64-winnt
x86
x86-linux
x86-solaris
x86-winnt
$

So what is causing this? Why is environment variable "ARCH" expected to
have a value different from "$(arch)"? In fact, running

$ ARCH= eselect profile list
[1] default/linux/amd64/17.1 (stable)
...
[35] default/linux/amd64/17.0/musl/hardened/selinux (exp)
$

succeeds, which is slightly puzzling, at least for me :-/

But if that's the way it has to be, I can live with it by just setting my
"eselect" alias to "eselect='ARCH= eselect --color=no'", which works.

In any case thanks for your time and effort :-)

Sincerely,
Rainer

Skimming farther upward reveals the string "x86_64" being derived
in line ">>>>33:" from environment variable "ARCH" which is defined
export ARCH=$({ arch || uname -m || echo unknown ; } 2> /dev/null)

You should open a bug to explain that ARCH variable is already defined
in your shell environment. As a consequence the results on the following

Hm, I'm not at all sure this would qualify as a bug. A while after hav-
ing traced this problem down, I faintly remembered that in ma early Gen-
too days I had a similar problem with "eix". In both cases the depen-
dance on environment variable "ARCH" is not documented in the respec-
tive manual pages, and therefore it is in particular not pointed out
that Portage is using a different convention from the "arch" command for
naming hardware architectures.

So it's probably not a bug in the code, but rather "just" missing pre-
cision in the documentation -- and my personal experience is that such
things will hardly ever be corrected, because the REAL bugs in the code
just have higher priority :-/

Sincerely,
Rainer

***I CAN'T EVEN BUILD THE CURRENT GLIBC ON MY MACHINE***. It looks
more and more like somewhere somehow my profile selection got changed
after my previous glibc update.
I regularly back up incrementally to two large standalone backup
drives. Every so often, I tarball my $HOME dir and push the copy over
to my "hot backup" machine. I intend to do that tonight, followed by
selecting profile...
[15] default/linux/amd64/17.1/no-multilib (stable)
...and then running...

Having backed up, I selected the no-multilib (stable) profile. I
checked out how glibc would build...

====================================================================
[x8940][root][~] emerge -pv1 glibc

These are the packages that would be merged, in order:

Calculating dependencies... done!
Dependency resolution took 3.33 s.

[ebuild U ] sys-libs/glibc-2.36-r7:2.2::gentoo [2.36-r5:2.2::gentoo] USE="multiarch ssp (static-libs) -audit -caps (-cet) -compile-locales (-crypt) (-custom-cflags) -doc -gd -hash-sysv-compat -headers-only (-multilib*) -multilib-bootstrap -nscd -perl% -profile (-selinux) (-stack-realign*) -suid -systemd -systemtap -test (-vanilla)" 0 KiB
====================================================================

The forced (multilib) flag has changed to forced (-multilib). The
other USE flag change is (-stack-realign).

emerge -pv --changed-use --deep --update @world

calls for glibc to to be updated (-multilib*) and (-stack-realign*)

In addition, the profile change appears to cause 5 rebuilds...
sys-libs/ncurses (-stack-realign*)
sys-apps/sandbox (-32*)
virtual/libcrypt (-32*)
sys-libs/libxcrypt (-32*)
sys-devel/gcc (-multilib*)

The update is running. I'll check the emerge results after I get back
from some shopping and fish-n-chips.

The update is running. I'll check the emerge results after I get back
from some shopping and fish-n-chips.

To answer the question in the subject... YES! emerge update ran
smoothly, including etc-update and depclean. I'm still baffled as to
how/why my profile got changed in the first place. I've got another
minor complaint, but that'll be a separate thread.
