So, fixing cxx11 support shouln't have any regression, only the feature will start working, while it wasn't before [Other Info] * Doko ack'd the SRU, and it should be the best voice here, for sure better than mine :) This packages does not contain any __cxx11 symbols when installed. This causes the problem that user-space applications cannot link successfully to it. Recompile the (untouched) dpkg source package on the same machine and installing it solved the problem. There seems something in the package generation broken. Steps to reproduce try to compile the attached minimal example https://github.com/goldhoorn/clang-sandbox Errors: CMakeFiles/main.dir/main.cpp.o: In function `foo()': /tmp/clang-sandbox/main.cpp:25: undefined reference to `clang::NamedDecl::getQualifiedNameAsString[abi:cxx11]() const' CMakeFiles/main.dir/main.cpp.o: In function `clang::QualType::getAsString[abi:cxx11](clang::SplitQualType)': /usr/lib/llvm-3.4/include/clang/AST/Type.h:868: undefined reference to `clang::QualType::getAsString[abi:cxx11](clang::Type const*, clang::Qualifiers)' CMakeFiles/main.dir/main.cpp.o: In function `clang::ast_matchers::internal::matcher_matchesName0Matcher::matches(clang::NamedDecl const&, clang::ast_matchers::internal::ASTMatchFinder*, clang::ast_matchers::internal::BoundNodesTreeBuilder*) const': /usr/lib/llvm-3.4/include/clang/ASTMatchers/ASTMatchers.h:1439: undefined reference to `clang::NamedDecl::getQualifiedNameAsString[abi:cxx11]() const' CMakeFiles/main.dir/main.cpp.o: In function `clang::ast_matchers::internal::matcher_hasName0Matcher::matches(clang::NamedDecl const&, clang::ast_matchers::internal::ASTMatchFinder*, clang::ast_matchers::internal::BoundNodesTreeBuilder*) const': /usr/lib/llvm-3.4/include/clang/ASTMatchers/ASTMatchers.h:1411: undefined reference to `clang::NamedDecl::getQualifiedNameAsString[abi:cxx11]() const' /usr/lib/llvm-3.4/lib/libclangAST.a(ExprConstant.o): In function `handleIntIntBinOp((anonymous namespace)::EvalInfo&, clang::Expr const*, llvm::APSInt const&, clang::BinaryOperatorKind, llvm::APSInt, llvm::APSInt&)': (.text+0x6a35): undefined reference to `llvm::APInt::toString(unsigned int, bool) const' /usr/lib/llvm-3.4/lib/libclangAST.a(StmtPrinter.o): In function `(anonymous namespace)::StmtPrinter::VisitIntegerLiteral(clang::IntegerLiteral*) [clone .isra.302]': ...
