I am having KDevelop version 4.3.1 on my ubuntu box. I want the editor to use the ctags file generated manually. It does not detect tag file located at ~/projects/project_name/tags.

How do i make KDevelop use the ctags file ? Any answers/suggestions are appreciated.

KDevelop does not support ctags. The functionality provided by those should be greatly exceeded by what KDevelop's language support does automatically anyways.

What functionality are you looking for?
