Could not determine GDB version using command: sudo /usr/local/bin/gdb --version Eclipse (Mars) version (C programming language):
Eclipse IDE for C/C++ Developers
eclipse.buildId=4.5.0.I20150603-2000

MacOS version:
OS X Yosemite 10.10.3
HW: MacbookPro 15" (mid-2015) Retina

Problem:
Debug action causes following error message ("111" is both Project Name, and source 111.c file as well):

window title: "Problem Occurred"
Error message: 
'Launching 111' has encountered a problem. 
Could not determine GDB version using command: sudo /usr/local/bin/gdb --version
sudo: no tty present and no askpass program specified

As far as I understand - that GBD module was removed from MacOS X, so I probably need to install manually one. 
I am newcomer in Mac, and trying installing upon different forums - I didn't succeed yet.

Probably, there maybe changes required as well in: 


  Debug Configurations (Run->Debug Configuration->"Debugger" tab). 
  Or/and as well in:
  Eclipse -> Preferences -> C/C++ -> Debug -> GDB


Please answer me - who installed recently by him-/her- self. Since old (more than year from now) forums may describe other case compared to problem I need to solve.

Please provide exact steps how to manage.
