Slot Conflic Inhibiting Update

Message

I'm trying to update my @world set, and can't, since the solution to making it work would involve installing llvm-core/flang, which can't install due to a slot conflict:

Code: Select all

!!! Multiple package instances within a single package slot have been pulled
!!! into the dependency graph, resulting in a slot conflict:

I've tried oneshoting all the packages that it would update (as per recommendation from the wiki), but that causes a similar issue. How do I solve this?

Post by Hu » Sat Dec 20, 2025 7:07 pm

flang requires updating llvm to a matching version. You have installed llvm-related packages that require the current version. Is emerge --ask --depclean empty? Do you want flang installed, or did Portage pick that due to some USE flag? What exactly did you try as a oneshot command?

I can't depclean, as there are some packages that need to be updated first.

I need flang to replace the GNU Fortran implementation, since that isn't compatible with my compiler flags (since the latest version) and I don't want to have to set up yet another build environment.

The oneshot command was: emerge -1 llvm-runtimes/{openmp,offload,compiler-rt,compiler-rt-sanitizers,clang-runtime} llvm-core/{llvm,clang}.

leyvi · Post by **leyvi** » Sun Dec 21, 2025 6:53 pm

OK, now I've got a similar but different problem:

Code: Select all

/usr/lib/llvm/21/bin/clang: symbol lookup error: /usr/lib/llvm/21/bin/clang: undefined symbol: LLVMInitializeARCTarget, version LLVM_21.1

This message appears whenever I try to update a package using LLVM, which is most of them. I don't use the ARC architecture on my system, so what's going on?

Post by Hu » Sun Dec 21, 2025 7:28 pm

Without knowing what commands you have been running, I can only speculate how you got into a state where depclean fails.

I suggest temporarily abandoning use of flang until you can get everything else updated and in good order. At the very least, flang is trying to pull in a newer llvm:21, and you aren't yet ready to do that.

Your oneshot appears to be missing (at least) llvm-core/lld. There might be other things missing from it.

I don't know how you got into the state that LLVM is broken. What have you changed since it last worked? Your output from before indicates that you had ARC enabled, and would be disabling it with an update. In general, the LLVM_TARGETS are forced because disabling them can break things like this, and so needs to be done with great caution.

Looks like I've borked my LLVM install... which is needed to fix itself. Should I just bootstrap it with GCC, then rebuild it with the result? Or maybe something else?

leyvi · Post by **leyvi** » Fri Jan 02, 2026 12:15 pm

Still an issue for me, by the way... and it turns out I can't build llvm-core/clang without clang...

Post by **sam_** » Fri Jan 02, 2026 1:37 pm

I refer you to the unanswered questions above.

leyvi · Post by **leyvi** » Fri Jan 02, 2026 2:08 pm

Ah, didn't realize that was a question. Yes, I did change the contents of LLVM_TARGETS, I removed a few irrelevant target architectures (M68K for example).

Post by **sam_** » Fri Jan 02, 2026 2:59 pm

Not as precise as I would've liked, but OK. Anyway, you've learned why all the targets for LLVM are forced on.

I recommend you use binpkgs to recover from a stage3 and https://wiki.gentoo.org/wiki/Fix_my_Gentoo

Here's the thing though: I need LLVM v21.1.x, and it seems that some of the dependencies of that version of clang are present, and some are not, look:

Code: Select all

root ~ (0) $ emerge -1G =llvm-core/clang-21.1.8
[gentoobinhost] Local copy of remote index is within TTL and will be used.

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

It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously.  If such a conflict exists in
the dependencies of two different packages, then those packages can
not be installed simultaneously.

For more information, see MASKED PACKAGES section in the emerge man
page or refer to the Gentoo Handbook.


!!! The following installed packages are masked:
- dev-lang/rust-1.84.1-r2::gentoo (masked by: package.mask)
- dev-lang/rust-1.87.0-r1::gentoo (masked by: package.mask)
- dev-lang/rust-1.89.0::gentoo (masked by: package.mask)
For more information, see the MASKED PACKAGES section in the emerge
man page or refer to the Gentoo Handbook.

How do I resolve this?

As I read that output, this is the usual problem that you're implicitly not allowing Portage to do all the installations needed to keep the system consistent. If you want to update clang, then you also need to let Portage update lldb to a version compatible with the new clang.

Ah. Could you maybe tell me how I might enable such installations?

Run full world update. Those partial updates do not allow for the complete graph to be considered and what's not in the sub-graph of llvm but is depended on by something that is, cannot be rebuilt.

Or add manually to the command line all the packages that are relevant to the update. As suggested by Hu, at least lldb. The list could take some work to figure out.

Or try adding --complete-graph to your emerge command, but I don't think that ever did what I wanted it to do.

Georgi

It looks like there is no prebuilt package for lldb... what now? (Adding llvm-core/lldb to the command did make the conflict go away, at least.)

EDIT: Actually what was the original command? I now read in your first post you tried to update your world set, but did you add -D? Trying to update only a set without -D may cause similar issues.

You build it, but why do you need it at all?

If emerge --deselect lldb says it removed it from world, then you might have emerged it by mistake. If you remember you installed it intentionally or the previous command said it couldn't find it in world, let it build.

Otherwise, what does emerge -pvc lldb say?

p.s. don't forget to add -1 to your update command so you don't pollute world.

Best Regards,
Georgi

Yeah, I've been oneshoting everything here.

I installed lldb because I needed to debug something (go figure

).

I'm not using it now, so I guess it can't hurt to deselect it...
