I'm new to emacs and I'm trying to make it work as an IDE like code blocks which I've been using quite a lot so i downloaded and installed the cedet package and SrSpeedbar but I have no clue how to build a project in emacs the same way codeblocks or other IDEs do. so any link to a package that does that or a easy method would be very helpful. thanks in advance
There is the EDE package in the CEDET, that provides some functionality for building projects, but this depends on which language & build tool you're using. If you're build tool isn't supported directly by EDE, you can still use ede-generic-project, and specify compilation command in project's local variables - see EDE information on more details.
You can find some information for start in my article on CEDET.
