[Bug 1501300] Re: Wily (15.10) this package got not compiled with __cxx11 support

[Matthias Goldhoorn]

mitko: it seems the i386 does not finish because the build-servers are too slow, however the x64 build is finished.
I have no clue howto tell the buildserver to wait longer for the result for the i386 build. of the llvm-3.7. But i recomment we move this 3.7 discussion to the other bugreport

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.

  Steps to reproduce try to compile the attached minimal example
  https://github.com/goldhoorn/clang-sandbox

  
  Errors:
