#yocto #sdk - meta-clang undefined references

Monsees, Steven C (US) #50688 I am building meta-clang (sumo based 6.0.1), with cmake (3.8.2), all under a standard SDK “rocko based” (2.4.1)… Are the following routines accessible/supported under meta-clang ? libgbe.so: undefined reference to `clang::DiagnosticIDs::~DiagnosticIDs()' libgbe.so: undefined reference to `clang::TextDiagnosticPrinter::TextDiagnosticPrinter(llvm::raw_ostream&, clang::DiagnosticOptions, bool)' libgbe.so: undefined reference to `clang::DiagnosticsEngine::~DiagnosticsEngine()' libgbe.so: undefined reference to `clang::CompilerInvocation::CreateFromArgs(clang::CompilerInvocation&, char const const, char const const, clang::DiagnosticsEngine&)' libgbe.so: undefined reference to `clang::CompilerInvocationBase::~CompilerInvocationBase()' libgbe.so: undefined reference to `clang::PCHContainerOperations::PCHContainerOperations()' libgbe.so: undefined reference to `clang::CompilerInstance::createDiagnostics(clang::DiagnosticConsumer, bool)' libgbe.so: undefined reference to `clang::DiagnosticsEngine::DiagnosticsEngine(llvm::IntrusiveRefCntPtr<clang::DiagnosticIDs>, clang::DiagnosticOptions, clang::DiagnosticConsumer, bool)' libgbe.so: undefined reference to `clang::CodeGenOptions::CodeGenOptions()' libgbe.so: undefined reference to `clang::CompilerInstance::~CompilerInstance()' libgbe.so: undefined reference to `clang::CompilerInstance::CompilerInstance(std::shared_ptr<clang::PCHContainerOperations>, clang::MemoryBufferCache)' libgbe.so: undefined reference to `clang::EmitLLVMOnlyAction::EmitLLVMOnlyAction(llvm::LLVMContext)' libgbe.so: undefined reference to `clang::CompilerInstance::ExecuteAction(clang::FrontendAction&)' libgbe.so: undefined reference to `clang::CompilerInvocationBase::CompilerInvocationBase()' libgbe.so: undefined reference to `clang::CompilerInstance::setInvocation(std::shared_ptr<clang::CompilerInvocation>)' libgbe.so: undefined reference to `clang::CodeGenAction::takeModule()' libgbe.so: undefined reference to `clang::DiagnosticIDs::DiagnosticIDs()' thanks, Steve
