Arch Linux User Repository

IWYU v0.23 is out, but clang v19 has not been released in Arch Linux. Please don't flag out-of-date until the new clang version is available. Thanks.

@Winterreise Thanks that worked!

@arpit Hey, try to remove the older version and reinstall it will solve this.

clang18 is available in Arch repos, but this package requires clang<18.0.0. Can this package support clang18?

Apologies, I flagged as out-of-date before I saw your comment on clang18.

Updated PKGBUILD with all the suggestions. Thanks!

Note: version 0.22 doesn't build properly with llvm17, must wait until clang/llvm 18 is available in Arch Linux

This wasn't building for me in a clean chroot, so I took a chance to simplify the package, the following worked for me:

@xeruf The llvm/clang packages in official Arch Linux repositories were recently updated to version 16, so you don't have to compile it yourself. Of course, if you use a different distribution, you need to ask elsewhere.
