Ensure that you have the necessary packages to compile programs that use
libusb (on Debian or Ubuntu systems, you might need to do apt-get
install libusb-dev | on Arch systems, you might need to do sudo
pacman -S libusb-compact). After that, unpack and compile the source code
with:
install libusb-dev libftdi-dev | on Arch systems, you might need to do sudo
pacman -S libusb-compact). As libusb-0.1 is used, you may also need to
install a compatibility layer for libusb-1.0 (for example,
libusb-compat-git on MSYS). After that, unpack and compile the source
code with:

tar xvfz mspdebug-version.tar.gz
cd mspdebug-version
make

On Windows systems with MSYS, you may also need to install a regex
implementation such as libgnurx.

On Debian Ubuntu systems sudo apt-get install libreadline-dev may be
required. On Arch systems sudo pacman -S readline may be required.
If you don't want GNU readline support, you can invoke make with:
