           Summary: http://libcxx.llvm.org/ build instructions invalid for
                    linux
           Product: libc++
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: All Bugs
        AssignedTo: hhinnant at apple.com
        ReportedBy: cppljevans at suddenlink.net

The web page:

  http://libcxx.llvm.org/

uses:

  export TRIPLE=-apple-

which, I assume, is invalid for linux systems, but there's no
mention of this on the page.

Also, there's:

  sudo ln -sf path-to-libcxx/lib/libc++.1.dylib libc++.dylib

which won't work for linux since the shared library has a
different suffix than .dylib:  On linux (or, to be precise
on ubuntu) the name is:

  libc++.so.1.0

In addition, the buildit script needs to be modified as
reported in this post:

and the instructions about symlinks in /usr/lib need to be modfied
as reported in this post:
