[SOLVED] FYI: rust-1.46.0 on Slackware 14.2 needs extra/llvm/llvm-8.0.1

Just a note to help someone else later

From a fresh upgrade-all to pull in updates from the 9/23:

[zakame:~] % ls /var/log/packages/rust*

/var/log/packages/llvm-3.8.0-x86_64-2

This would seem surprising, but a little more perusal of the stable changelog provides illumination:

+--------------------------+ Sat Jul 20 22:11:38 UTC 2019 extra/llvm/llvm-8.0.1-x86_64-1_slack14.2.txz: Upgraded. ... +--------------------------+ Mon Sep 24 21:37:09 UTC 2018 extra/llvm/llvm-6.0.1-x86_64-1_slack14.2.txz: Upgraded. Moved this package from /patches, since it is not really a required patch. Unless you're planning to rebuild Firefox or Thunderbird (or have some other use-case for a more recent LLVM than was shipped with Slackware 14.2) you probably don't need to upgrade to this package, and it was reported that doing so impacted at least one package provided by slackbuilds.org. So, /extra seems like a better place for this package.

So, it would seem that a simple upgradepkg $MIRROR/slackware64-14.2/extra/llvm/llvm-8.0.1-x86_64-1_slack14.2.txz would provide the missing libLLVM-8.so dependency; not sure if the warning from then still applies, but it should be enough to get rustc working:

root@jazz:~# upgradepkg ~ftp/pub/Linux/slackware/slackware64-14.2/extra/llvm/llvm-8.0.1-x86_64-1_slack14.2.txz          
...

Package llvm-3.8.0-x86_64-2 upgraded with new package /home/ftp/pub/Linux/slackware/slackware64-14.2/extra/llvm/llvm-8.0.1-x86_64-1_slack14.2.txz.

root@jazz:~# rustc --version
rustc 1.46.0

Addendum: as the llvm package is included in multilib/massconvert32.sh, there will be a mismatch if installing the extra version of the package:

[zakame:~] % ls /var/log/packages/llvm*
/var/log/packages/llvm-8.0.1-x86_64-1_slack14.2
/var/log/packages/llvm-compat32-3.8.0-x86_64-2compat32

I suppose a workaround for now would be to fetch the 32bit extra version, then use convertpkg-compat32 on it:

root@jazz:~# curl -sLO http://ftp.slackware.com/pub/slackware/slackware-14.2/extra/llvm/llvm-8.0.1-i586-1_slack14.2.txz
root@jazz:~# convertpkg-compat32 -i llvm-8.0.1-i586-1_slack14.2.txz 
...

Slackware package /tmp/llvm-compat32-8.0.1-x86_64-1_slack14.2compat32.txz created.

Package created:  /tmp/llvm-compat32-8.0.1-x86_64-1_slack14.2compat32.txz
root@jazz:~# upgradepkg /tmp/llvm-compat32-8.0.1-x86_64-1_slack14.2compat32.txz

zakame, thank you for posting all this, sure applies to my thread.

I did

slackpkg install rust

and got what you did

rustc --version rustc: error while loading shared libraries: libLLVM-8.so: cannot open shared object file: No such file or directory

as the change log comments say

patches/packages/rust-1.28.0-x86_64-1_slack14.2.txz: Added. Since Rust is now a requirement to compile Firefox and Thunderbird we are adding it here. Unless you will need to recompile those (or need to compile other code written in Rust), it is an optional addition.

I don't think I'll worry about rust at this time, I don't need to recompile either of those.

Not to necrobump but I really really need to read, or at least bare minimum skim through, changelogs again.
After recent kernel patch forced to restart the server my electrs failed with the same dependency error and this post helped. Thank you,
