Is there a C++ gdb GUI for Linux?

Eclipse CDT will provide an experience comparable to using Visual Studio. I use Eclipse CDT on a daily basis for writing code and debugging local and remote processes.

If you're not familiar with using an Eclipse based IDE, the GUI will take a little getting used to. However, once you get to understand the GUI ideas that are unique to Eclipse (e.g. a perspective), using the tool becomes a nice experience.

The CDT tooling provides a decent C/C++ indexer that allows you to quickly find references to methods in your code base. It also provides a nice macro expansion tool and limited refactoring support.

With regards to support for debugging, CDT is able to do everything in your list with the exception of reading a core dump (it may support this, but I have never tried to use this feature). Also, my experience with debugging code using templates is limited, so I'm not sure what kind of experience CDT will provide in this regard.

For more information about debugging using Eclipse CDT, you may want to check out these guides:

gdb -tui works okay if you want something GUI-ish, but still character based.
