Re: #yocto llvm support #yocto

Monsees, Steven C (US)


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…

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/
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
