FIXME/TODO:

• maintainer email address
• can we build against llvm-19-dev? Prob some compat issues here: llvm 19 is older, the -dev package is not like the source tree so unlikely to work as-is.

We dont have support for out of tree builds and we dont build with llvm19, as a lot of stuff has changed in eld and is compatible only from LLVM 21 onwards.

maintainer email id can be eld@noreply.github.com ?

Ok I'll see what I can do to sort out the gap, then.

No - it'll need to be someone responsive to community support requests. That email address looks like it wouldn't get delivered to someone who will answer.

Thank you so much @androm3da for adding support with all the three major linux package managers!

Would it be possible to directly use LLVM 21 and provide eld release/21.x for apt package manager? (we will always need to match the LLVM version with the eld version; eld release/21.x will require LLVM release/21.x)

I see now that the unstable and testing channels of debian use 21.1.6. So maybe it makes sense for main branch of eld to depend on 23.x and if we're inclined maybe we could cherry-pick this/these commits back to release/21.x / release/22.x where we'd pick the corresponding llvm.
