If you're comfortable with emacs, irony + rtags does pretty much all the IDE-type things I need it to. You can autoconfigure rtags based on your build system (supports basically all of them). you get variable type hints, function arg hints, contextual autocomplete (including template stuff), jump to definition, find references, you can fuzzy find and jump to methods/identifiers/symbols across your project, compiler warnings highlighted inline, it's a pretty good setup.
