When installing nativesdk-clang-tools, for a sdk, it installs clang compiler

[Lorac]

Describe the bug
Given that I only want the clang tooling but not the compiler. If I decide to install nativesdk-clang-tools it will install clang compiler which isn't what I wanted to install.

To Reproduce
Add nativesdk-clang-tools to TOOLCHAIN_HOST_TASK

Expected behavior
Only install nativesdk-clang-tools binaries and the needed .so, but not the compiler and its headers, intrinsic, etc.

Desktop (please complete the following information):

• OS: Linux, Debian 11

its interesting who is pulling nativesdk-clang. Can you look into output of bitbake -g nativesdk-clang-tools or post the output here as well.

[Lorac]

nativesdk-clang-tools is a package and can't be used to do that on kirkstone. I think you mean bitbake -g nativesdk-clang ?

[Lorac]

I know that mesa depends on clang. But it doesn't RDEPENDS, maybe the way mesa depends on clang is incorrect?

Well may be add -g to sdk target build

[Lorac]

task-depends.dot of the -g sdk target build: https://file.io/qFVjQv9bSvNX

[kraj]

who is pulling nativesdk-clang-glue I think thats what is pulling it in.

[Lorac]

clang-crosssdk-x86_64.do_prepare_recipe_sysroot depends on nativesdk-clang-glue

[Lorac]

@kraj do you have any updates on this?

[kraj]

I finally found some time to look into it and I see

% readelf -d clang-apply-replacements

Dynamic section at offset 0x1dd08 contains 32 entries:
  Tag        Type                         Name/Value
 0x0000000000000001 (NEEDED)             Shared library: [libclang-cpp.so.16]
 0x0000000000000001 (NEEDED)             Shared library: [libLLVM-16.so]

Which means the tools depend on llvm and clang library. Which will be pulled in as dependency and it will automatically pull in nativesdk-clang-libclang-cpp and nativesdk-clang-libllvm

so this dependency "nativesdk-clang-tools" -> "nativesdk-clang" is interesting and is the root of your issue.
so I think we need to see why packager/opkg thinks this should be added to rdepends. Since I dont see it being
asked to be in rdeps by recipe.
