can not build clang toolchains in yocto 5.4-zeus

[jin1]

hi all,

I am playing imx8qm iwave board with yocto 5.4-zeus , I neeed clang toolchains. I have added 

TOOLCHAIN = " clang"   in local.conf,

but after  bitbake imx-image-full -c populate_sdk to generate the toolchain,

but there is no clang after installing the toolchains.

before I played  yocto L4.14.98-2.0.0_GA . it worked well.

why yocto 5.4-zeus no clang toolchains?

any help ?

Thank you

Hello jin1,

I think whats missing it dependency on C++ runtime. default is libstdc++ so I guess you have to add a dependency on gcc-runtime

I found one issue , I forgot to add meta-clang into the source code , but after  adding it and adding TOOLCHAIN ?= " clang"   in local.conf, there is still a error to build

bitbake imx-image-full  (I want to build it successfully ,and then to build bitbake imx-image-full -c populate_sdk)

why nn-imx can not pass builing? before there was no TOOLCHAIN ?= " clang"   in local.conf, it's OK to build image and normal toolchains.

any more help?

Thank you

after I remove CORE_IMAGE_EXTRA_INSTALL += " chromium-ozone-wayland" in local.conf.

clang toolchain can build and work well.
