This guide shows the process of setting up and compiling Smoothie V2 with the libcxx development environment.
This involves cloning the necessary repositories (libcxx, NuttX apps, and NuttX), installing libcxx into the NuttX source tree, applying patches, and building the firmware for the Bambino-200e board.
The following command line session demonstrates the complete build process:

The build process involves these key steps:
Clone the libcxx repository from Bitbucket
Clone the NuttX apps repository
Clone the NuttX core repository
Install libcxx into the NuttX source tree using the installation script
Apply configuration and source code patches for the Bambino-200e board
Configure the build system for the Bambino-200e with helloxx config
Build the firmware with make
The final output is nuttx.bin, which can be flashed to the Smoothie V2 board.
