.. tab-set::

   .. tab-item:: Preparations

        * Make sure current dir is $HOME
        
        .. code-block:: c

                $ cd $HOME
 

        * Create a directory with name "Rt-Thread_with_QEMU" and move to that directory using below commands:

        .. code-block:: c

                $ mkdir Rt-Thread_with_QEMU
                $ cd Rt-Thread_with_QEMU

 
        * Install Git on your PC if it is not installed already:

        .. code-block:: c

                $ sudo apt-get install git


        * Download RT-Thread source code using below command:

        .. code-block:: c

                $ git clone https://github.com/RT-Thread/rt-thread.git

        * Install QEMU if not installed using below command:

        .. code-block:: c

                $ sudo apt-get install qemu

        * Install Scons if it is not pre-installed:

        .. code-block:: c

                $ sudo apt-get install scons

        * Install ncurses Library using below command:

        .. code-block:: c

                $ sudo apt-get install libncurses5-dev

        * Move to the following path:

        .. code-block:: c

                $ cd ~/Rt-Thread_with_QEMU/rt-thread/bsp/qemu-vexpress-a9

        * Open file "rtconfig.py" and check EXEC_PATH(in line 33). The corresponding path to the bin directory corresponding to the compiler should be "/usr/bin/" as shown below:

        .. code-block:: c

                qemu-vexpress-a9$ vim rtconfig.py

                    EXEC_PATH   = os.getenv("RTT_EXEC_PATH") or r"/usr/bin"
