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
|
|
|
|
Lean requires Python2 or Python3. If you do not have a Python installation on your machine,
|
|
please download and install one from [Python.org](https://www.python.org/downloads/windows).
|
|
Also please make sure that your `PATH` environment variable includes the installed
|
|
Python directory (i.e. `C:\Python27`).
|
|
|
|
[The official webpage of msys2][msys2] provides one-click installers.
|
|
We assume that you install [msys2][msys2] at `c:\msys64`.
|
|
Once installed it, you can run msys2 shell from the start menu.
|
|
It has a package management system, [pacman][pacman], which is used in Arch Linux.
|
|
|
|
Here are the commands to install all dependencies needed to compile Lean on your machine.
|
|
|
|
```bash
|
|
# 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 ninja, cmake
|
|
pacman -S 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.

## Build Lean using Boost
|
|
|
|
To install Boost in the [msys2] shell, use the following command:
|
