Bug#639214: eglibc: changes to paths concerning crt1.o, crti.o and crtn.o breaks building LLVM Trunk

John,

Thanks for the prompt reply. I've posted this discussion to the LLVM List and will see what becomes of it.

Thank you,

- Marc

Hi Marc,

With the most recent changes of moving the object files under
/usr/lib/x86_64-linux-gnu/ the linker to build Clang/LLVM breaks.

A workaround is to add symlinks for crt1.o, crti.o and crtn.o back
under /usr/lib.

>From /usr/share/doc/libc6/NEWS.Debian.gz:

  Starting with the eglibc package version 2.13-5, the libraries are
  shipped in the multiarch directory /lib/$arch instead of the more
  traditional /lib. Similarly the includes are now shipped in
  /usr/include/$arch instead of the more traditional /usr/include.

  The toolchain in Debian has been updated to cope with that, and most
  build systems should be unaffected. If you are using a non-Debian
  toolchain to build your software and it is not able to cope with
  multiarch, you might try to pass the following option to your
  compiler:

    -B/usr/lib/$arch -I/usr/include/$arch

Does clang support similar options?

See also http://llvm.org/bugs/show_bug.cgi?id=6541 which suggests to
me that upstream is interested in out-of-the-box support for the new
paths.

Reassigning to "general" and merging with the relevant bug, since this
is far from a libc-specific problem.  See [1] for some background.

Thanks and hope that helps,
Jonathan
