Re: [yocto] #yocto llvm support and meta-clang
Khem: There are at least 4 zeus released tags, can you vouch for one of them to work properly with meta-clang ? Porting to dunfell might not be possible at this time... Would it be possible to build the dunfell drop of meta-clang under zeus ? Although we do not plan on using clang in the kernel, I did a quick build to see if I would get a similar error... Seeing: error: unknown argument: '-maccumulate-outgoing-args' for kernel build Any ideas what might be missing ? Again Note: If I remove/comment out the line TOOLCHAIN ?= "clang" in conf/local.conf, the build is much faster, and it builds without the error, also appears not to require/include "llvm" component in build. I do not believe the full package was actually built/enabled, but no errors and image is functional. Steps used to build a clean Kernel image with meta-clang... (1) Added meta-clang to bblayers.conf (2) Added Setting for meta-clang in conf/local.conf: TOOLCHAIN ?= "clang" The build is much slower due to "clang-native-9.0.1-r0 do_compile"...

I think for future development you should look into dunfell or newer
since those are supported releases.

clang toolchain has evolved rapidly in past few years and so you might
find major changes from release to release and also SDK builds are
relatively
new, I think dunfell and newer is where its properly working without
much issues.

Re: [yocto] #yocto llvm support and meta-clang
There appears to be an issue with build zeus based meta-clang under zeus
platform...
I followed steps off meta-clang page, and from the work I did with meta-clang
under "Rocko" about a year ago, a lot has changed under the hood...
Working under zeus 3.0.4... EXT SDK appears fully functional, I require
CLANG/LLVM for future development...
Never seen this error before, did I miss a patch or possibly a step ?
Clean build area...
(1) Add meta-clang to bblayers.conf
(2) Added EXT SDK Settings for meta-clang :
SDKIMAGE_FEATURES_append = " staticdev-pkgs"
SDK_EXTRA_TOOLS = " \
nativesdk-cmake \
nativesdk-clang \<---Only appears to download/build llvm when present
"
TOOLCHAIN_HOST_TASK_append = "${SDK_EXTRA_TOOLS}"
The build is much slower due to "native-clang-9.0.1-r0 do_compile"...
EXT SDK build error seen:
