Title:
Wily (15.10) this package got not compiled with __cxx11 support
Status in llvm-toolchain-3.4 package in Ubuntu:
In Progress
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.
Steps to reproduce try to compile the attached minimal example
