This page documents the instructions for setting up a Windows build using msys2, which is a fairly complete build of MinGW + the msys tools. It is pretty self contained and fixes several pesky bugs with the traditional implementation. It's also smaller and has a convenient package manager, pacman.
NB: You can extract .tar.xz files with 7Zip: http://www.7-zip.org/
- Download this package: http://sourceforge.net/projects/msys2/files/Base/i686/msys2-base-i686-20131208.tar.xz/download
- Download 32bit GHC 7.6.3: http://www.haskell.org/ghc/dist/7.6.3/ghc-7.6.3-i386-unknown-mingw32.tar.bz2
Extract the msys2 base package somewhere like C:\msys32
Extract the GHC binary somewhere like C:\msys32\ghc-7.6.3
Launch the shell with C:\msys32\mingw32_shell.bat
- Download this package: http://sourceforge.net/projects/msys2/files/Base/x86_64/msys2-base-x86_64-20131208.tar.xz/download
- Download 64bit GHC 7.6.3: http://www.haskell.org/ghc/dist/7.6.3/ghc-7.6.3-x86_64-unknown-mingw32.tar.bz2
Extract the msys2 base package somewhere like C:\msys64
Extract the GHC binary somewhere like C:\msys64\ghc-7.6.3
Launch the shell with C:\msys64\mingw64_shell.bat
Setting up your PATH
Create a ~/bin directory for the cabal.exe (and whatever else you want.) Also, put GHC in your $PATH by appending the following to ~/.bashrc:
$ mkdir ~/bin $ echo 'export PATH=/ghc-7.6.3/bin:$PATH' >> ~/.bashrc $ echo 'export PATH=$HOME/bin:$PATH' >> ~/.bashrc
We'll also go ahead and add the default cabal.exe binary installation path:
$ echo 'export PATH=/c/Users/YourUserNameHere/AppData/Roaming/cabal/bin:$PATH' >> ~/.bashrc
Make sure you restart your shell.
Installing packages & tools
The msys2 package uses pacman (the venerable ArchLinux package manager) to manage packages. Once you're set up, upgrade everything, and install some dependencies:
$ pacman -Syu $ pacman -S python2 git wget tar gzip binutils gcc autoconf make libtool automake xz
Now install a cabal.exe prebuilt binary, and install alex and happy:
$ wget http://www.haskell.org/cabal/release/cabal-install-220.127.116.11/cabal.exe $ mv cabal.exe ~/bin $ cabal update $ cabal install alex happy $ alex --version $ happy --version
A Quick build
You should now be able to build GHC:
$ cd ~ $ git clone https://github.com/ghc/ghc.git $ cd ghc && ./sync-all --testsuite --nofib --extra get $ ./boot && ./configure $ make -j5
Yes! Parallel make works!
