MRC/Tutorials/Setting up your project

Of course, we not only want to use software during this course, but we want to create some! Let's create a workspace directory in which we will put this code:

mkdir ~/emc

Let's start off with a simple example project. Go inside the ~/emc directory, and create a new folder with the name awesome_project:

cd ~/emc
mkdir awesome_project

Often, the code files are not put directly in the root of a folder, but in a directory called src. This stands for source, and is called this way because the files in there are the source of the compilation process, and are converted into binaries (files that are no longer human-readable, but are understandable for the machine). So, let's go. Remember that when using cd (and many other commands in linux) you can use tab-completion to type quicker, i.e, try:

cd a<<< now push the TAB key >>>

You will see that the terminal fills out the rest, because awesome_project is the only directory in the current directory that starts with an a. Ok, create the src directory, and go inside:

mkdir src
cd src

Finally, let's do some programming! You should have finished the C++ tutorials by now, so you know how to create a basic C++ program. Let us do it now. Open your favourite editor to create a file called example.cpp and put some code inside:

#include <iostream>

int main()
{
    std::cout << "Hello world!" << std::endl;
    return 0;
}
