Anuj:

I picked up the tarball for for the baseline dunfell tools platform to
update host tools...

I am seeing it compile cleaner but for one issue causng ld to fail:

/disk0/scratch/smonsees/yocto/workspace_1/builds2/sbcb-
default/tmp/work/x86_64-linux/intel-graphics-compiler-native/1.0.11-
r0/recipe-sysroot-native/usr/include/llvm/Support/CommandLine.h:1331:
undefined reference to `vtable for
llvm::cl::opt<std::__cxx11::basic_string<char, std::char_traits<char>,
std::allocator<char> >, false,
llvm::cl::parser<std::__cxx11::basic_string<char,
std::char_traits<char>, std::allocator<char> > > >'

Isn't LLVM brought in along with clang under meta-clang ?

Is there a missing build dependency ?

Thanks,
Steve

It looks like the gcc version is too old on your host for this to work.
