GDB pretty printing

[eike]

GDB pretty printing not worked for me. I was followed by instructions http://codelite.org/LiteEditor/GdbPrettyPrinting.
OS Xubuntu 15.10
Codelite version 9.00 (installed through apt-get install).
Python 2.7.10
GNU gdb (Ubuntu 7.10-1ubuntu2) 7.10
gcc (Ubuntu 5.2.1-22ubuntu2) 5.2.1 20151010
Can someone help me?

I have find solution.
comment this code in Startup Commands.

Code: Select all

#from libstdcxx.v6.printers import 
#register_libstdcxx_printers
#register_libstdcxx_printers (None)

And add this code:

Code: Select all

# Load the pretty-printers.
from printers import register_libstdcxx_printers
register_libstdcxx_printers(gdb.current_objfile())

to libstdcxx\v6\__init__.py

[eranif]

Do you have a reference on why you added this code? was something changed lately in GDB python API?
Thanks

I searched in google for "RuntimeError: pretty-printer already registered: libstdc++-v6\n Error while executing Python code.\n" and foud solution in thi url:
