[SOLVED]enable multilib

Hello. After enabling multilib is needed installing 32bit libs? If yes, how do that?

/etc/pacman.conf

[multilib]
Include = /etc/pacman.d/mirrorlist

sudo pacman -Syyu

nothing

[root@home etc]# sudo pacman -Syyu

Re: [SOLVED]enable multilib

is needed installing 32bit libs?

Only when/if necessary. Packages requiring lib32* will automatically pull in their required (lib32) dependencies when needed.

[root@home etc]# pacman -Ssq lib32 | pacman -S -
[COLOR="Red"]error: unresolvable package conflicts detected
error: failed to prepare transaction (conflicting dependencies)
:: lib32-jack2 and lib32-pipewire-jack are in conflict[/COLOR]

Install one XOR another, not both!

# pacman -S lib32-pipewire-jack

or

# pacman -S lib32-jack2

\\\

[root@home etc]# pacman -Ssq lib32 | pacman -S - 

Why?...

Re: [SOLVED]enable multilib

You have already installed a couple dozen or so multilib packages according to that output.  But while both of these points were noted by d.ALT, I think the emphasis was backwards: yes, the error message is clear, but much more importantly, why on earth would you try to install every package in the multilib repo?  Be greatful this failed.  Don't do that.

Thanks for answer!
I thought that if enable multilib it they all must be installs?
Can you explain please how its works? How i know that some multilibs is needed?

multilib isn't any different from all other repos in that regard

and how i know what same is needed?

Do you use pipewire?
Do you need *any* jack implementation?

Re: [SOLVED]enable multilib

Pacman is your package manager.  It handles dependencies.  If you install something that depends on lib32 dependencies, pacman will install them.  That's it.

Unless you are writing your own code that specifically uses a library, and you need to compile a 32-bit binary from that code, you'd never have any reason to explicitly install any lib32 library.  There are only a small handful of packages from [multilib] that one might explicitly install (e.g., wine, or steam) and one of these was almost certainly the reason you enabled the repo in the first place.  When you installed one of these, pacman properly pulled in the dependencies as already noted.  This would (most likely) be why you already have 25 lib32-* packages already installed.
