If you are expecting an IDE (pretty windows where you can edit code and the like) GCC doesn't do that. It is just a compiler.
You might want to install a nice IDE package. Suggested IDEs are:
(You'll need KDE components installed to use this one. It shouldn't affect your Gnome setup.)
Personally, I tend to use plain-text editors for everything. Those I like:
(Extensive syntax highlighting support and I can make it use WordStar key commands.)
 If you can't escape, type
and press ENTER.[/edit]
(You've probably already got this installed.)
I hate emacs
, but a lot of people love it. You've probably already got this installed too.
If you can't escape, press Ctrl-X Ctrl-C
Hope this helps.
 Oh yeah, almost forgot. You can run the GCC by opening the command prompt, changing to the directory where your program is, say /prog/myapp.cpp
, and typing
|g++ -Wall -pedantic -o myapp myapp.cpp|
What that means is "start g++, give all warnings, be strict about language standards, output to 'myapp' (instead of 'a.out') and the source file(s) is 'myapp.cpp'."
