cleaning up llvm, clang etc

[snIP3r]

hi all!

after my recent system update i encountered, that i have some very old versions of clang, llvm and depending packages installed. but i am not sure how to clean this without breaking my system. e.g. clang:

emerge --ask --depclean --verbose clang

selected: 12.0.1 13.0.1 14.0.6-r1

so i would deplean in this order:
1. clang
2. clang-runtime
3. compiler-rt
4. compiler-rt-sanitizers
5. llvm
6. binutils

may this be the right order or am i completely wrong?
any help would be greatly appreciated!

thx in advance

You can cleanup your world favorite file ( /var/lib/portage/world) with a text editor, or with "emerge --deselect cat/pkg"
and then run

Code: Select all

emerge -a --depclean

[snIP3r]

thx @josef.95 but i do not want to cleanup the entire system but just clang/llvm...

[NeddySeagoon]

snIP3r,

I suspect you have world pollution.
Either some of those old versions ane in world, because you forgot --oneshot, or they are dependencies of something else in world.
That's fine, if that's what you want ... until portage wants to rebuild something that has been removed from the repo.
Then you have to dig out and maybe update the old ebuild.

[snIP3r]

hi neddyseagoon!

i think so too, but i alway updated as i was used to: emerge --sync and then emerge -uavDN world

removed clang and other mentioned packages version 10 and 11 and did a emerge -uavDN world and emerge @preserved-rebuild and everything seems to be fine so far.
so i think i can savely continue?

actually emerge --depclean clang shows me this:

llvm-core/clang
selected: 12.0.1 13.0.1 14.0.6-r1
protected: none
omitted: 15.0.7-r1 16.0.6

so i will keep 15.0.7-r1 and 16.0.6 as suggested

thx snIP3r

[NeddySeagoon]

snIP3r,

Yes, that's correct. Something in world needs them.

[logrusx]

so i will keep 15.0.7-r1 and 16.0.6 as suggested

thx snIP3r

Stable version is 20. You really need to clem up world, as suggested above. If you don't feel confident doing that yourself, post it here.
But first, as an exercise, I recommend going through it and think about every entry, if you know what it's doing there. You should have in world only entries that you explicitly want on your system. They should not be dependencies of something else, unless they can be used independently.

Best Regards,
Georgi

@logrusx: thx for the help. as suggested i unmerged older version. but i cannot update to clang version 20 altthough it is noticed:

Code: Select all

Post emerge output, emerge --info and the contents of /var/lib/portage/world

[snIP3r]

if i explicitly emerge llvm-core/clang i get:

Code: Select all

emerge -av llvm-core/clang

but if i do a regular emerge -uavDN world i get:

so i assume there is something wrong?

Go through all of the *-libs and dev-* categories. If you don't know why something is there, remove it. Then run emerge -ca and see if there's something you want to keep. If there is, emerge --noreplace it and repeat. When you clean up the system, post the new contents of world.

acct-user stuff should not be in world as well as binutils, I think some of the app-crypt stuff too, bash as well, dev-build should be mostly pulled in by other stuff so if you don't recognize something from that category, remove it as well.

Some of the sys-apps should go as well, for example openrc, as i should be pulled in by the profile, I'm not sure about busybox, if you don't know why it's there, it probably shouldn't be, portage as well, sysvinit.

Gcc shouldn't be there as well, virtual/perl-* stuff is suspicious.

Also go through your package.use and see if there's something related to clang/llvm. Also check if you have something in package.mask that may be related.

And finally, I recall a circular dependency between llvm components, so they should be explicitly listed on the command line, but let's doe the above first.

snIP3r,

Your world file contains a lot of junk. This indicates that you have not been using --oneshot with emerge when building for trouble shooting.
Members of the @system set, libraries and virtuals should never appear. There are a few exceptions, as always.

Code: Select all

virtual/cron
virtual/dev-manager
virtual/editor
virtual/man
virtual/perl-File-Spec
virtual/perl-IO-Socket-IP
virtual/perl-Storable
virtual/perl-libnet
virtual/perl-podlators
virtual/perl-version
virtual/ssh 

can all go. Virtuals are a trick that portage uses to perform dependency resolution when one of several packages are required.
If any in the list are installed, the virtual is satisfied. When none are installed, the first named package in the list is installed.
Consumers depend on the virtual. dependencies of other packages should never be in world. Hence my opening statement.

Code: Select all

dev-build/autoconf
dev-build/automake
dev-build/automake-wrapper
dev-build/libtool
dev-build/meson
dev-build/netsurf-buildsystem ??
dev-build/ninja 

Should all be @system set members or dependencies of other things. As a result, removing them from world should not allow portage to uninstall them.

Code: Select all

dev-libs/apr
dev-libs/apr-util
dev-libs/boost
dev-libs/cyrus-sasl
dev-libs/geoip
dev-libs/glib
dev-libs/icu
dev-libs/ivykis
dev-libs/libbsd
dev-libs/libltdl
dev-libs/libmspack
dev-libs/libtasn1
dev-libs/libunistring
dev-libs/libutf8proc
dev-libs/mpc
dev-libs/mpfr
dev-libs/oniguruma
dev-libs/openssl 
...
dev-perl/libintl-perl
dev-perl/libwww-perl 
...
media-libs/faad2
media-libs/flac
media-libs/fontconfig
media-libs/freetype
media-libs/gd
media-libs/libexif
media-libs/libjpeg-turbo
media-libs/libmad
media-libs/libogg
media-libs/libpng
media-libs/libvorbis
media-libs/openjpeg
media-libs/tiff
media-libs/xvid
...
net-libs/courier-authlib
net-libs/gnutls
net-libs/serf
...
sys-libs/efivar
sys-libs/glibc
sys-libs/ldb
sys-libs/liburing
sys-libs/pam
sys-libs/readline
sys-libs/talloc
sys-libs/tdb
sys-libs/tevent
sys-libs/timezone-data
sys-libs/zlib 

Are all libraries, so should probably not be in world. There are a few oddballs, like libvirt, which is not a library, so go carefully.
That's the easy ones done.

Code: Select all

dev-perl/<module>

should all be depended on by consumers, so they are candidates for removal from world.

Code: Select all

app-editors/nano

Is free with virtual/editor. If you have another text editor installed,

Code: Select all

app-editors/vim

portage will offer no remove nano. It needs to be here to keep nano.

Code: Select all

app-shells/bash 

is in @system.

Code: Select all

dev-lang/python:2.7 

Portage won't use that. If you need it, keep it.

Code: Select all

sys-apps/portage
sys-apps/sysvinit
sys-devel/binutils
sys-devel/binutils-config
sys-devel/bison
sys-devel/gcc
sys-devel/gcc-config 

are @system set members.
sys-apps/sysvinit is only included in non systemd profiles.

I'm sure that there are more candidates for removal too. That's a scan with Mk1 eyeball.

There is or was a script on the wiki to do a test. It's very slow as it goes through world, one package at a time and pretends to remove it

hi all!

i think i messed up something. first, what i have done:
before start cleaning i backed up the old world file.
then i deleted some entries as suggested and after a deletion i did:

Code: Select all

emerge -uavDN world
revdep-rebuild
emerge @preserved-rebuild

after this i did an

Code: Select all

emerge -ca

went through the list and deleted packages i think not needed anymore.

after some cycles i saw packages in the list for deletion i am sure they are needed (e.g. rust-bin)
but also clang/llvm would be completely whiped off my system:

Code: Select all

llvm-core/clang
    selected: 16.0.6
   protected: none
     omitted: none

 llvm-core/llvm
    selected: 16.0.6
   protected: none
     omitted: none

 llvm-core/clang
    selected: 15.0.7-r1
   protected: none
     omitted: none

ok, so i got panic and recopied the backed up org. world file and repeated emerge -ca. but now, clang/llvm will also be removed completely....

what am i doing wrong here?
hope someone can help me with this mess....

greets
snIP3r

Don't panic, nothing that's needed will be depcleaned, put your new world back, maybe share it here, emerge --noreplace rust-bin, run full world update and and then share emerge -pc output.

Georgi
