[SOLVED]gcc-libs and gcc-libs-multilib are in conflict

Can't update today.

[glow@GlowArch ~]$ sudo pacman -Syuv

 community is up to date
 multilib is up to date
 catalyst is up to date
:: Starting full system upgrade...

error: unresolvable package conflicts detected
error: failed to prepare transaction (conflicting dependencies)

I assume there is some update going on, i will try again in some time.

This is normal when gcc gets updated. You typically have to wait a bit while gcc-libs-multilibs is moved from [testing].

This was my understanding reading older posts, thanks.

GloW_on_dub, clfaroon4 mentions 1 of the possible causes for this error.

However, another cause is that 1 of your installed programs is not the multilib version, but the standard non-multilib version..

you can check if this case is valid by for you by running pacman -Syu --ignore gcc-libs .
NOTE : the output will only be useful if gcc-libs and gcc-libs-multilib have different versions.

You're right, i have indeed a dependency problem because of this aur package, acml-gfortran, wich have in it's dependencies gcc-fortran instead of gcc-fortran-multilib

The thing i don't understand is how have i been able to install gcc-fortran with acml-gfortran, without trying to install gcc-libs and discovering the conflict at that time,
and also why the fact that there is a gcc-fortran and gcc-libs update without the corresponding update in the multilib version discover the conflict.

I've commented the aur package, so the maintainer will soon fix the problem, yet i don't understand fully why this conflict have appeared now.

Observe that gcc and gcc-libs are at version 4.9.0-2, where gcc-multilib and gcc-libs-multilib are 4.9.0-1 (flagged to be updated to 4.9.0-2).

I've seen that, but how could i install gcc-fortran without installing gcc-libs ?

Oh, I think I see what you mean. I had the same "pacman update problem" last night but with "gcc-objc" instead of "gcc-fortran". I, too, was kind of surprised I was able to use "gcc-objc" with "gcc-libs-multilib".

I guess they're compatible.

Anyway, I chose to solve the update problem by uninstalling "gcc-objc" and installing "gcc-objc-multilib". No reason not to have multilib, as far as I can tell.

GloW_on_dub · 2014-05-09 14:01:29

Indeed, installing, gcc-fortran-multilib solved the problem, with acml-gfortran complaining at all, so i guess pacman is smart enough to understand that the multilib package contain the non-multilib also.
