I might be hitting the same or at least a related bug: I am using clang 3.7 to compile an application that itself uses libclang3.7 to do some C++ parsing. I get unresolved symbol errors from the linker. Namely this one single error, many times:
undefined reference to `clang::NamedDecl::getQualifiedNameAsString() const' The same source code compiles fine using gcc 5.2 so it really seems it's a problem with the string ABI change of gcc and stale libraries. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to llvm-toolchain-3.4 in Ubuntu. https://bugs.launchpad.net/bugs/1501300 Title: Wily (15.10) this package got not compiled with __cxx11 support Status in llvm-toolchain-3.4 package in Ubuntu: Confirmed Bug description: 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.
