Prusa-Firmware/PF-build.sh

#!/bin/bash 
# This bash script is used to compile automatically the Prusa firmware with a dedicated build environment and settings
# 
# Supported OS: Windows 10, Linux64 bit
# Beta OS: Linux32 bit
#
# Linux:
#
# Windows:
# To execute this script you gonna need few things on your Windows machine
#
# Linux Subsystem Ubuntu
# 1. Follow these instructions
# 2. Open Ubuntu bash and get latest updates with 'apt-get update'
# 3. Install zip with 'apt-get install zip'
# 4. Install python3 with 'apt-get install python3'
# 5. Add command 'ln -sf /usr/bin/python3.5 /usr/bin/python' to link python3 to python.
#    Do not install 'python' as python 2.x has end of life see https://pythonclock.org/
# 6. Add at top of ~/.bashrc following lines by using 'sudo nano ~/.bashrc'
#
#    export OS="Linux"
#    export JAVA_TOOL_OPTIONS="-Djava.net.preferIPv4Stack=true"
#    export GPG_TTY=$(tty)
#
#    and confirm them. Restart Ubuntu bash
#
# Or GIT-BASH
# 1. Download and install the correct (64bit or 32bit) Git version https://git-scm.com/download/win
# 2. Also follow these instructions https://gist.github.com/evanwill/0207876c3243bbb6863e65ec5dc3f058
# 3. Download and install 7z-zip from its official website.
#    By default, it is installed under the directory /c/Program Files/7-Zip in Windows 10 as my case.
# 4. Run git Bash under Administrator privilege and navigate to the directory /c/Program Files/Git/mingw64/bin,
#    you can run the command ln -s /c/Program Files/7-Zip/7z.exe zip.exe
#
# Useful things to edit and compare your custom Firmware
# 1. Download and install current and correct (64bit or 32bit) Notepad++ version https://notepad-plus-plus.org/download
# 2. Another great tool to compare your custom mod and stock firmware is WinMerge http://winmerge.org/downloads/?lang=en
# 
# Example for MK3: open git bash and change to your Firmware directory 
# <username>@<machine name> MINGW64 /<drive>/path
# bash build.sh 1_75mm_MK3-EINSy10a-E3Dv6full
#
# Example for MK25: open git bash and change to your directory 
# gussner@WIN01 MINGW64 /d/Data/Prusa-Firmware/MK3
# bash build.sh 1_75mm_MK25-RAMBo13a-E3Dv6full
#
# The compiled hex files can be found in the folder above like from the example
# gussner@WIN01 MINGW64 /d/Data/Prusa-Firmware
# FW351-Build1778-1_75mm_MK25-RAMBo13a-E3Dv6full.hex
#
# Why make Arduino IDE portable?
# To have a distinguished Prusa Firmware build environment I decided to use Arduino IDE in portable mode.
# - Changes made to other Arduino instances do not change anything in this build environment.
#   By default Arduino IDE uses "users" and shared library folders which is useful as soon you update the Software.
#   But in this case we need a stable and defined build environment, so keep it separated it kind of important.
#   Some may argue that this is only used by a script, BUT as soon someone accidentally or on purpose starts Arduino IDE
#   it will use the default Arduino IDE folders and so can corrupt the build environment.
