I am not a developer, but for my work I trace a lot of codes. It is actually rather difficult reading other people's code, especially for bigger projects.
Source Insight is a great application that stores all the symbols in a data base, so you can see a new function being called, click on it and see how the function is written. You can see all the referrer of a object or jump to a caller. You don't need to break the train of thought and think up shell commands just to find these things every time you ran into a new variable/structure/function from some other files.
I have it running on WINE, but there are little glitches that sometimes gets in the way.
I know people will mention C-scope, I've tried it, but it really isn't the same. So, with so many huge open source projects out there for Ubuntu, are there native tools to help read them efficiently?
EDIT:
Thanks for the suggestions, but does CODE::BLOCKS or CodeLite provide abilities to see the function that the mouse clicked on without jumping to it, so I can see the caller and callee at the same time?
Best Answer
Code::Blocks might be an option.
Code::Blocks is a free C++ IDE built to meet the most demanding needs of its users. It is designed to be very extensible and fully configurable.
An IDE with all the features a developer need, having a consistent look, feel and operation across platforms.
Built around a plugin framework, Code::Blocks can be extended with plugins. Any kind of functionality can be added by installing/coding a plugin. For instance, compiling and debugging functionality is already provided by plugins!
Runs on windows too
I'll let someone else post about codelite and widestudio so you can pick one
