You can install Anjuta 2.4.1 from the Synaptic package manager. You also need to install a few development packages. I do not know if there is a nice meta-package such as build-essential (used to install compilers et al), so I'll just ask you to install the packages by hand. A more elegant way would be very much appreciated to see in the comments.
$ sudo apt-get install build-essential libgtkmm-2.4-dev autogen automake libtool intltool libglademm-2.4-dev
That is the order of installation when you go trial by error inside Anjuta to compile a project. Each package draws in several other packages. Also, if you have the Ubuntu 8.04 DVD in your drive, most of these packages will be installed in a jiffy. We have the Greek localisation enabled, so bear with us. Thanks to Giannis Katsampiris for completing the recent update of the Anjuta 2.4 localisation.
Once Anjuta is installed, you are presented with the Anjuta main window.
We then click on File/New/Project (Αρχείο/Νέο/1. Έργο),
We click on Forward here.
There are many many project types. We wade through and we pick to use C++ and GTKMM (C++ bindings for GTK+). We could pick any other variation; GTKMM was a request from the Ubuntu-gr mailing list.
We then fill in some contact details.
There is an option to specify at this stage external packages. We opt not to specify them now.
Once you click Apply (Εφαρμογή) - the button with the green tick, Anjuta will create an initial dummy package (actually a hello world application), and will run automatically the equivalent of ./configure for you.
Now, this is the final screen, when you start working. Here you would click on Κατασκευή/Κατασκευή έργου (Build/Build Project), so that the project gets compiled.
Then, you would click on Κατασκευή/Εκτέλεση προγράμματος... (Build/Run program...) to run the program!
Here is shows that we have located the source file (main.cc), and we see main().
It takes about 3 second to compile a program with g++ (at least on my system). Therefore, the dead time between (a) Let's compile it and (b) Oh, I am running my program!, is under 5 seconds, which is good.
