two versions of llvm

[bagas]

Hello.
How to determine who is pulling the sys-devel/llvm dependencies?
Why are there two heavy compilers in the system?

You have two versions of llvm if some packages depend on the older version and others depend on the newer version. The situation will normally resolve, when all packages are using the newer version.

After you have installed both versions, you can check with

Did not understand you.

Heavy system update.

[sMueggli]

Without seeing the output it is impossible to tell you, why you have both versions installed.

In my case it is because media-libs/mesa-23.1.9 pulls in llvm-16.0.6. Will be solved with the stabilisation of mesa-23.3.

For example, on my system:

Alternatively one can use equery which exists to get information about packages.

Strange behavior of package dependencies.

Check out bug 923228. Work is in progress.

If you follow the discussion, you'll see that it solves a few other issues too.

If we limited it to one static version, that wouldn't be received well by our users when porting to newer LLVMs, and we'd have the opposite complaint. It would also largely defeat the point of LLVM being slotted at all. So, yes, easier, but not the right solution for Gentoo.

It would be overkill to suddenly restrict the options available to users substantially because of a bug we know how to fix, using a method which was kind of overdue anyway (given it fixes some other problems as well).

There is also a world beyond stable.

Forcing static, single versions would be considered a serious regression and not at all an improvement.

Yeah, mgorny has since posted it to the ML as well (PR was just for some pre-ML review to see if we liked the idea).

You don't have anything else to do other than pestering devs on a forum?
