Instructions for the easiest way to compile MAME under Windows 10 or Windows 11
(as of April 3rd 2026)

1. Download msys2 from https://www.msys2.org and install in the default dir c:\msys64
   Uncheck 'Run msys2 now' and click finish.

2. On START menu type "msys2 clang64" and then 'Pin to Start' for future use.
   Run it and within the Msys2 window copy/paste ALL 5 lines then press ENTER.
   This will install the compiler, download the latest MAME sources and compile
   MAME in ONE easy step. The echo at the end will make a beep when the compile
   is finished. It can be removed if you don't want a beep on completion.

pacman -S git make mingw-w64-clang-x86_64-clang mingw-w64-clang-x86_64-gcc-compat mingw-w64-clang-x86_64-python mingw-w64-clang-x86_64-lld
git clone https://github.com/mamedev/mame.git
cd mame
make -j5 OVERRIDE_CC=clang OVERRIDE_CXX=clang++ ARCHOPTS=-fuse-ld=lld
echo -e "\a"


3. The end.
When done mame.exe is at the following location...
C:\msys64\home\[username]\mame\mame.exe


To update the MAME source and recompile, run 'msys2 clang64' and type...
cd mame
git pull
make -j5 OVERRIDE_CC=clang OVERRIDE_CXX=clang++ ARCHOPTS=-fuse-ld=lld
echo -e "\a"
