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++14 compiler.
Installing dependencies
The official webpage of MSYS2 provides one-click installers. Once installed, you should run the "MSYS2 MinGW 64-bit shell" from the start menu. Do not run "MSYS2 MSYS" instead! MSYS2 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.
pacman -S make mingw-w64-x86_64-cmake mingw-w64-x86_64-ccache mingw-w64-x86_64-gcc git
Then make sure the following is included in your PATH:
export PATH=$PATH:/mingw64/bin
You should now be able to run these commands:
gcc --version
cmake --version
Then follow the generic build instructions in the MSYS2 MinGW shell, using
cmake ../.. -G "Unix Makefiles" instead of cmake ../... This ensures that cmake will call sh instead
of cmd.exe for script tasks.
Install lean
You can use the install ninja/make target to install Lean into, by default,
./build/release/stage1/msys64/lean/. To change this, add -DCMAKE_INSTALL_PREFIX=path/you/want
to your initial cmake invocation.
Running
You can run lean --version to see if your binaries work.
If you want a version that can run independently of your MSYS install then you need to copy the following dependent DLL's from where ever they are installed in your MSYS setup:
- libgcc_s_seh-1.dll
- libstdc++-6.dll
- libgmp-10.dll
- libwinpthread-1.dll
The following linux command will do that:
cp $(ldd lean.exe | cut -f3 -d' ' | grep mingw) .
