Details

Description:
LLVM doesn't ship with static libraries (pretty sure the change is here: https://gitlab.archlinux.org/archlinux/packaging/packages/llvm/-/commit/3e452a15b68d156a9ef5608e8f6e1870d192d954). I think that's fine for consumers of LLVM, but I'm working on a compiler, and I need the static libraries as part of the build process for the Rust crate llvm-sys. In general, any program that links to LLVM statically and uses llvm-config will expect these libraries.

Steps to reproduce:
Just try `llvm-config`:
$ llvm-config --libnames --link-static

llvm-config: error: missing: /usr/lib/libLLVMBinaryFormat.a

(...and so on)

Reason for closing:  Won't implement
Additional comments about closing:  Use the "prefer-dynamic" feature of llvm-sys or build your own copy of LLVM (you could also try the prebuilt one from llvm.org).

Not a common use case :) Please see previous discussion in  FS#77644  and also see PM's comment here [1]. You might need to compile your own custom/AUR LLVM as hinted at in the llvm-sys doc.

Adding to what Toolybird said, llvm-sys supports linking to the dynamic LLVM library if you enable the "prefer-dynamic" feature.
