Answer 1

For C / C ++:

• Use CDT in Eclipse

• In the root directory of the project, create the Makefiles project:

  cmake -G 'Eclipse CDT4 - Unix Makefile'

• Import the project using Eclipse-> File-> Import-> General-> Existing Projects

• Enjoy code completion with Ctrl-Space

For python

• Install PyDev
• In Eclipse Go to ... Window-> Settings-> PyDev-> Interpreters
• Configuring PyDev, choosing which Python interpreter to use
• Add / usr / local / lib / python 2.7 / dist-packages (or other valid paths) to the system libraries
• Add cv (or cv2) to forced built-in functions
• Enjoy the code with Ctrl-Space

Answer 2

If you are trying to use python opencv, I found

from cv2.cv import * 

in the site-packages / cv.py file, for this case I had to use import:

 import cv2.cv as cv #instead of import cv 

to complete the code.
