I noticed similar behavior… I am running zeus 3.0.4, “devtool sdk-install llvm” will get llvm 8.0.1… When I build meta-clang, and I set TOOLCHAIN?=”clang” in local.conf it appears to grab llvm-project-source-9.0.1-9.0.1…
this is intentional, when you use meta-clang, then llvm is preferred from LLVM since them we have consistent version of llvm for clang and others.

Hi Steven, I used meta-clang in my recipes and I noticed that: 1. The current release of poky uses LLVM v11.1.0 by default (poky/meta/recipes-devtools/llvm/llvm_git.bb) 2. Meta-clang requires LLVM v12.0.0 (meta-clang/conf/layer.conf defines LLVMVERSION = "12.0.0") As a result just including meta-clang into bblayers.conf will require bitbake to build a new version of LLVM and rebuild everything which uses it Anton
