[WIP] Building OpenOCD 64-bit on Windows 10 with MSYS2 for ULX3S FTDI JTAG

README.txt

# 32-bit build by me: https://github.com/bluecmd/tools/blob/master/openocd-32bit-ulx3s.zip

# This is for 64-bit
# BUG: Ends up depending on msys anyway: https://github.com/libusb/libusb/issues/829

# Note: We use MSYS for the shell to compile an MinGW64 target.
# That way the resulting binary will not rely on MSYS.

# Make sure the FTDI drivers are installed for the virtual COM port.
#  As of this writing I am using "CDM v2.12.28 WHQL Certified"

# Install MSYS2
https://www.msys2.org/

# Update pacman until everything is updated
pacman -Syuu

# Install development tools
pacman -S base-devel mingw-w64-x86_64-gcc p7zip

# Download latest libusb
wget https://github.com/libusb/libusb/releases/download/v1.0.24/libusb-1.0.24.7z
7z x -olibusb ./libusb-1.0.22.7z
