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

[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

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

Dependency resolution took 1.43 s.

=====================================================================

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

  ***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...

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

  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.

  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.

I do not see anything particular in your emerge --info.
What is your eselect version ?

You can get bash debug output by running the following :

Hopefully this will show what's going on into /tmp/debug.log.

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
   ia64
   loong
   m68k
   mips
   ppc
   ppc-macos
   ppc64
   ppc64-linux
   riscv
   riscv-linux
   s390
   sparc
   sparc-solaris
   sparc64-solaris
   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

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
commands are different :

> $ ARCH=x86_64 portageq envvar ARCH
> x86_64

> $ portageq envvar ARCH
> amd64

An this finally leads to eselect failure in some cases :

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
