how to remove llvm-20.1.0?

[saski4711]

hello,

recently emerge pulled llvm-20.1.0 parallel to llvm-19 although there is no obvious dependency for llvm-20. How can I safely unmerge and mask llvm-20 and keep llvm-19?

I've tried LLVM_SLOT="19" in ym make.conf but that didn't do anything. Any advice?

cheers

Try emerge -pvc =llvm-core/llvm-20.1.0 to see if nothing depends on it.
Afaik, each version of clang is tied to a llvm version, so it might require to also remove clang-20 as well as all the llvm/clang associated toolchain to get back to 19 - it can turn messy.

That does not do anything on its own. First provide the output of the command suggested above as well as your emerge --info. I can't believe a user registered more than 20 years ago would provide so little context.

A recent thread about a circular dependency pops in my mind but I need more context.

(As a hint for others helping the user when more information is provided: it's possible that there's some packages installed which still use llvm.eclass.)

Thanks for the hint but this looks like a ~ system as 20.0.1 is still not stable, at least on my system. I guess older packages do not require a testing clang/llvm.

My apologies for being a little short on details .

Aside from clang I can see no other dependencies tied to llvm.

Confirmed my suspicion that this is a testing system, I'm not sure if Sam's hint applies, nor I know how to identify if there are packages still using llvm.eclass.

Here's the list of llvm/clang toolchain I know, some packages might not be installed depending on your USE flags. Just remember to add a = and package version such as "=llvm-core/llvm-20.1.0" for each one of them. Or I think (not sure) you can try with just the :20 suffix "llvm-core/clang:20". Portage will probably offer to downgrade (and not remove) those who are not slotted.
