    Build Emacs-w64 with MSYS2/MinGW-w64 with Native Compilation

Instructions are modified from emacs-w64 Wiki page by zklhp. Many thanks for sharing!


Download the latest MSYS2 from this download page.


Install MSYS2 to, for example, C:\msys2 (make sure no space in path to avoid unwanted problems).


Optionally prettify the MSYS2 console mintty with ~/.minttyrc to make it more pleasing to eyes. Thanks to this awesome theme!

Remove all /c/* paths in $PATH by adding this to .bashrc and restart mintty.

This is important to avoid interference from programs installed
on the same machine, especially if you have Cygwin installed.
# Remove '/c/*' from PATH if running under Msys to avoid possible 
# interference from programs already installed on system. Removal 
# with awk is copied from http://stackoverflow.com/a/370192.
if [ $(uname -o) == 'Msys' ]; then
    export PATH=`echo ${PATH} | awk -v RS=: -v ORS=: '/c\// {next} {print}' | sed 's/:*$//'`

The whole .bashrc is copied here.

Install packages required to build Emacs.

Follow instructions on this page first.
pacman -Syu
pacman -Sy
pacman -Sy\

    libcurl \
    pacman \
    ncurses \
    libintl
    
Close mintty and restart it, do this again.
pacman -Su

Build Emacs!

Change target accordingly, the directory in which the freshly built Emacs binaries, libraries, and docs live.
