Are there any IDEs (Integrated Development Environments) for Linux?

In the longer term, you should consider the possibility that you’re solving the wrong problem: That is, long-time Unix developers find that emacs’s (and xemacs’s) or jed’s tight integration with gcc/g++, ctags, and gdb makes them more productive than do the RAD / GUI-builder / IDE tools listed at the above link. This is clearly a question of taste, but please consider the traditionalist Unix user’s toolkit, as well. You should also consider whether that the language and libraries one picks aren’t considerably more significant than are glossy editing tools. (This “rant” item dates from the 1990s, when it was common to troll Linux users with claims that no IDEs exist for Linux, which then drew out emacs/gdb fanboys who fell for the bait and verbosely sermonised about why IDEs are Bad and Wrong, with the trollers then claiming victory and repeating the cycle a month later — when in fact the fundamental assumption about Linux IDEs was massively wrong
