In my application, I'm dealing with a larger-size classes (over 50 methods) each of which is reasonably complex. I'm not worried about the complexity as they are still straight forward in terms of isolating pieces of functionality into smaller methods and then calling them. This is how the number of methods becomes large (a lot of these methods are private - specifically isolating pieces of functionality).
However when I get to the implementation stage, I find that I loose track of which methods have been implemented and which ones have not been. Then at linking stage I receive errors for the unimplemented methods. This would be fine, but there are a lot of interdependencies between classes and in order to link the app I would need to get EVERYTHING ready. Yet I would prefer to get one class our of the way before moving to the next one.
For reasons beyond my control, I cannot use an IDE - only a plain text editor and g++ compiler. Is there any way to find unimplemented methods in one class without doing a full linking? Right now I literally do text search on method signatures in the implementation cpp file for each of the methods, but this is very time consuming.
