Why doesn't Eclipse use GDB for printing?

I am using Eclipse 4.4.2 on Ubuntu 14.04 and GDB 7.7.1. I am trying to check the contents of some containers of the C ++ standard library in the Eclipse debugger.

What I tried so far: following the instructions here , I ran the command

svn co svn://gcc.gnu.org/svn/gcc/trunk/libstdc++-v3/python

Copy it to /home/myusername/prettyprint.

Then I copied this text to my .gdbinit:

python
import sys
sys.path.insert(0, '/home/myusername/prettyprint/python')
from libstdcxx.v6.printers import register_libstdcxx_printers
register_libstdcxx_printers (None)
end

When I started gdb, I received this error message:

Traceback (most recent call last):
  File "<string>", line 4, in <module>
  File "/home/myusername/prettyprint/python/libstdcxx/v6/printers.py", line 1266, in register_libstdcxx_printers
    gdb.printing.register_pretty_printer(obj, libstdcxx_printer)
  File "/usr/myusername/gdb/python/gdb/printing.py", line 146, in register_pretty_printer
    printer.name)
RuntimeError: pretty-printer already registered: libstdc++-v6

I was looking for help on this and found that the second last line in the file ( register_libstdcxx_printers (None)) was not needed, so I deleted it. Then, when I started gdband typed:

info pretty-print

I got this output, indicating that the backend was installed correctly:

    std::__7::vector
    [... many more lines of output omitted]

For a good measure, I added the following lines to .gdbinit:

set print pretty on
set print object on
set print static-members on
set print vtbl on
set print demangle on
set demangle-style gnu-v3
set print sevenbit-strings off
