Build Third-Party Component
###########################

Building third-party components is a standard procedure after setting up the cross-compilation environment. If the project uses ``configure``, specify ``--host=aarch64-poky-linux`` during configuration.

In this example, we will compile ``htop``, a popular system-monitoring tool, for the DevKit. ``htop`` provides an interactive, real-time view of system processes. It offers detailed insights into CPU usage, memory consumption, and task management, making it more powerful than basic tools like ``top``.

.. note:: 
    
    Before you run the following commands, ensure you have :ref:`setup the cross compilation environment <cross_compilation_setup>`.

.. code:: bash

    user@palette-container-id:/home/docker/{project}$ git clone https://github.com/htop-dev/htop.git
    user@palette-container-id:/home/docker/{project}$ cd htop
    user@palette-container-id:/home/docker/{project}/htop$ ./autogen.sh
    user@palette-container-id:/home/docker/{project}/htop$ ./configure --host=aarch64-poky-linux --prefix=/usr
    user@palette-container-id:/home/docker/{project}/htop$ make
    user@palette-container-id:/home/docker/{project}/htop$ file htop
    htop: ELF 64-bit LSB pie executable, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, BuildID[sha1]=07e842801a55cfdce80b25a0d6133f4c7dcc56a2, for GNU/Linux 3.14.0, with debug_info, not stripped

Now that you've compiled ``htop``, you can deploy it to the DevKit and run it on the target system.

.. code:: bash

    user@palette-container-id:/home/docker/{project}/htop$ scp htop sima@<DevKit IP>:~/

Then ssh to the DevKit and run the following command to see the output:

.. code:: bash

    davinci~/$ ./htop
