Eclipse only shows me the prototype of the shared library function, not the definition

Question

When I hover on a function, by using Ctrl+click, Eclipse sends me by default to the prototype of the function in the header file.

I'd like to see the definition of this function but I see no link when hovering or using the right click?

Is that something in the config I need to set?

It's a shared library by the way (I can compile my program without problem)

Answer 1

Okay I've found it. After having paste in one of my project folders the source code from which the shared library was compiled, I need to go into 'properties'>'C/C++ general'>'Preprocessor include'>'GNU C++' and in 'CDT User settings Entries' paste the path to the library source folder.

Ctrl+click then shows me directly the definition of the function. I can do Ctrl+click again (but on the .cpp file) to get the prototype (as before).

Other solution: Pressing F3, and F3 again.
