Lean for Windows
A native Lean binary for Windows can be generated using msys2. It is easy to install all dependencies, it produces native 64/32-binaries, and supports a C++11 compiler.
Installing dependencies
The official webpage provides one-click installers.
We assume that you install msys2 at c:\msys64.
Once installed it, you can run msys2 shell from the start menu.
It has a package management system, pacman, which is used in Arch Linux.
Here are the commands to install all dependencies needed to compile Lean on your machine.
# Install gcc (4.9.1)
pacman -S mingw-w64-x86_64-gcc
# Install mpfr, gmp, lua
pacman -S mingw-w64-x86_64-mpfr mingw-w64-x86_64-gmp mingw-w64-x86_64-lua
# Install python, ninja, cmake
pacman -S mingw-w64-x86_64-python2 mingw-w64-x86_64-ninja mingw-w64-x86_64-cmake
# Install git
pacman -S git
Close the msys2 shell and add c:\msys64\mingw64\bin into the PATH
environment variable.
