No index in Eclipse CDT project checked out from SVN

Issue

I have checked out a cross-compilation project from SVN on Eclipse (on a Linux system). I am unable to open a functions declaration from the functions's right-click context menu (or by pressing F3). Upon research, I found out I don't even have anything like Index -> .. in the project's right-click menu. I have tried a lot with the Preferences -> C/C++ -> indexer but no useful results. I am not using Eclipse to build it but there are no errors since I can build it using makefile

PS: Though there are a few questions with the matching title, but none of them helped me

Solution

Here is the solution found after a million attempts. The project should be checked-out as C/C++ project, by selecting import using new project wizard.. The index will NOT be available in the SVN projects checked-out directly. Hope it saves some one's time
