Hello Matthias, or anyone else affected,

Accepted llvm-toolchain-3.4 into wily-proposed. The package will build
now and be available at https://launchpad.net/ubuntu/+source/llvm-
toolchain-3.4/1:3.4.2-13ubuntu2.1 in a few hours, and then in the
-proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Title:
  [SRU] Wily (15.10) this package got not compiled with __cxx11 support

Status in llvm-toolchain-3.4 package in Ubuntu:
  Invalid
Status in llvm-toolchain-3.4 source package in Wily:
  Fix Committed

Bug description:
  [Impact]

  * with gcc-5 default, and llvm-3.4 built with the gcc-4.9, people
  can't link programs using cxx11 support

  [Test Case]

  * compile a program using cxx11 e.g. using boost libraries

  [Regression Potential]

  * llvm-3.4 is a compiler, and the change should affect only cxx11
  support (since the library is ABI compatible).

  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
