Building the doom3 source code on linux (Ubuntu) tutorial

"SCons is a software construction tool—that is, a superior alternative to the classic "Make" build tool that we all know and love." And fortunatley it is not all that hard to use either.

After doing all of that you're ready to compile move into your doom sourcecode directory and compile it like this

So now that you have the iDTech Engine you will need content. this is where you could reverse engineer the whole thing and create the content from scratch.. or copy Dooms 'base' folder into the newly created one.
