Hello Jim,
You must add your override of do_install_class-nativesdk() in the recipe
that builds clang/llvm that will not affect how gcc gets installed in
the SDK.
You can have as many do_install_class-nativesdk() overrides across
various recipes as you like, without them conflicting. Basically this is
how every tool from the SDK gets installed there.

Hi Liviu,
Thanks for the tip. I had everything but the override for
do_install_class-nativesdk().
One question please.
Will that override prevent the gcc compilers from being installed in
nativesdk? Or should I duplicate the existing
do_install_class-nativesdk(), and add the clang stuff?

Hello Yu, Jim
I think you can get the clang executable into the SDK installer script
with something like this:
1. Add this dependency in nativesdk-packagegroup-sdk-host.bb:
*RDEPENDS_${PN} += "nativesdk-<name-of-clang-recipe>"*
2. In the clang recipe add this install() overwrite for the nativesdk
class - this will install it into the SDK sysroot:
*do_install_class-nativesdk() {
install -d ${D}${bindir}
install -m 0755 clang ${D}${bindir}
}*
3. The clang recipe (I don't know if it has a recipe of its own, or
it's part of the LLVM recipe) should also inherit from nativesdk:
*BBCLASSEXTEND = "nativesdk"*
Basically this should get your clang executable inside the SDK
installer. Sure you can add more executables related to clang (like
the llvm-related ones) in the install_class-nativesdk() function.

I **think** I'm just inches away from success. I think I just need to invoke a
correct install command somewhere in the do_install function but so far I have
not managed to do so. But right now the alternative way of jamming the compiler
into the SDK sounds tempting to me.

Hi Jim,
How did you jam the clang compiler into the SDK tarball?

Hello Chan,
I have been working to a similar goal, to include clang in the toolchain to be
used for compiling applications to run on the target. Using clang to compile
the OS and kernel are not required or desired by me.
You may get some insight from the thread I started in November on the subject.
I'm not sure that this contains all of the posts on the subject. You may want
to search the archive for November.
I have not been successful yet in getting clang actually packaged in the
toolchain, in the Yocto build, but at least it builds. I have a postbuild
script that takes the built clang compiler from the work directory and jams it
into the SDK tarball that is embedded in the sdk install script.
