Under ../poky/meta/recipes-devtools the is "llvm"...
Devtool search <component>
Devtool sdk-install <component>
Will add this component to my EXT SDK...
Is this a fully functional llvm drop ?,
(i.e. is it compatible with meta-clang?, and can I use them together to build 3rd party extensions for my platform ?)
Is it better to add supported components this way rather than building them in directly to EXT SDK ?
Thanks,
Steve

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

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.

So, does anyone know proper usage here?
Is this a fully functional llvm drop under ../poky/meta/recipes-devtools ?
Is it compatible with meta-clang?, and can they be used together to build 3rd party extensions for my platform ?
Is it better to add supported components this way rather than building them in directly to EXT SDK ?
Also, any known issues with meta-clang under zeus 3.0.4 ?
Thanks,
Steve
