Hi all,
So I've been doing some experiments with latest ccls version on COPR [1]
and this is what I found:
1.- It won't build on rawhide
rawhide currently sports clang/llvm v20, and ccls simply fails to build
with that (this would require changes upstream since the LLVM libs have
changed).
2.- It builds in _some_ platforms with clang/llvm v17
- Builds go though in fedora40 (aarch64, x86_64), but rpm/check-rpaths
complains [2] (even though I used "Requires: llvm17-libs").
- On rawhide/x86_64 the clang c++/v17 compiler seems to be broken. [3]
- On rawhide/aarch64 the LLVM17 libraries seem incompatible (even though
they are good in fedora 40). [4]
So I think in order to have ccls up an running we'll have to build an
older clang/llvm combination (ccls tests require clang v6). But building
clang & llvm v6 just to have ccls is probably overkill.
So things look bad for ccls. I'll do some other experiments, and see if
there're any plans to support LLVM20 upstream in the future. Any other
ideas/suggestions to have ccls running are welcome.
Thanks and kind regards,
Antonio

Hi all,
Yes, Dan was kind enough to tell me exactly this.
I will take me some time, though, as I have some other priorities.
Thanks and kind regards,
Antonio

Hi Dan!
This is indeed appreciated. No better sponsor!
This will be my first contribution. I've read [1] and followed all
instructions there, but I'm stuck. What should I do now?
Because the package has been retired for too long, you need to submit
it for review request again as if it's a new package (base it on the
retired spec with any improvement that's necessary)
Mark the issue as blocking FE-NEEDSPONSOR, and probably reply here or
to Dan with the issue URL so he sees it.
Best regards,
