Title:
  gdb reports ImportError no module libstdcxx.v6.printers

Status in gdb package in Ubuntu:
  Invalid

Bug description:
  GDB attempts to use a python "pretty printer" and reports the
  following error:

  [Thread debugging using libthread_db enabled]
  Traceback (most recent call last):
    File "/usr/local/lib64/libstdc++.so.6.0.16-gdb.py", line 59, in <module>
      from libstdcxx.v6.printers import register_libstdcxx_printers
  ImportError: No module named libstdcxx.v6.printers
  [Inferior 1 (process 31059) exited normally]
  (gdb)

  GDB Version: GNU gdb (Ubuntu/Linaro 7.3-0ubuntu2) 7.3-2011.08

  I found that by doing the following it fixes the problem:

  svn co svn://gcc.gnu.org/svn/gcc/trunk/libstdc++-v3/python gdb_printers
  mv gdb_printers /usr/local/etc
  cd ~
  vi .gdbinit

  (copy & paste into .gdbinit)

  python
  import sys
  sys.path.insert(0, '/usr/local/etc/gdb_printers')
  from libstdcxx.v6.printers import register_libstdcxx_printers
  register_libstdcxx_printers (None)
  end
