Introduction

The old GitBash build environment is deprecated and we use now the Msys2 that supports a package system for updates.

Install Msys2

Download the msys2 installer from https://msys2.github.io

Install Msys2 following the instructions on the web site.
You can either install the i686 (32 bit) or x86_64 (64 bit) version, this applies to host used. Both installers support Win32 and Win64 shells.
Update Msys2 to the latest available binaries following steps 5 to 7 of Msys2 installation guide.

pacman -Syu

If you get build errors when pulling new code later, always try re-running "pacman -Syu" as that will often resolve build problems.

Username / Home directory

Msys2 creates the home directory using the current Username from Windows.
Be sure the home directory does not contains spaces and rename it if needed.

Check your home directory:

cd ~
pwd

Add LibrePilot MinGW repository

Add the following lines at the end of your /etc/pacman.conf file:

[librepilot-mingw]
SigLevel = Optional TrustAll
Server = http://download.librepilot.org/repo/mingw

Paste this code into the bash-window to add the above lines to /etc/pacman.conf

echo "[librepilot-mingw]" >> /etc/pacman.conf
echo "SigLevel = Optional TrustAll" >> /etc/pacman.conf
echo "Server = http://download.librepilot.org/repo/mingw" >> /etc/pacman.conf

Install the toolchain

The toolchain is used to build the software:
