This sounds great. Can you update the wiki page so that it says exactly what to do?
I’m copying Neil Mitchell who is interested in doing the same
Thank you!

Subject: Re: Problems with building GHC 7.8.3 on Windows
I have finally builded GHC 7.8.3 on Windows. The wiki page with MSYS2 that you linked to proved to be useful reference. Indeed using the latest 64 bit MSYS2 as building environment solved my problems. However there are some issues with the instructions presented:
-- the MSYS2 package that is linked to in the page fails to initial update. Using the latest official MSYS2 package does solve that ( https://sourceforge.net/projects/msys2/files/Base/x86_64 );
-- initial update has to be done along the instructions from http://sourceforge.net/p/msys2/wiki/MSYS2%20installation/ ;
There are some error outputs during initial update but they do not seem to cause any harm
I thing it might be a good idea to give stronger encouragement to use MSYS2 on the page with Windows-specific instructions. It suggests that old MSYS can be used successfully while it apparently fails and is not supported.

1. I see you've set ticket's 'Architecture' field to be 'x86_64' while make output suggests you try to build 32-bit ghc.
2. You are using 'old' MSys which is known to be problematic when building GHC. It's much better to use MSYS2 now: https://ghc.haskell.org/trac/ghc/wiki/Building/Preparation/Windows/MSYS2.
Also, remember, MSYS2 is only a *build environment*, so you can use 64-bit MSYS2 to build 32-bit GHC on 64-bit Windows. My experience is that 64-bit MSYS2 is more solid and stable than 32-bit MSYS2. And it's extremely important to remember you must *not* use msys2_shell.bat to start MSYS2 shell, only mingwXX_shell.bat (XX stands for 32 or 64) shall be used to start MSYS2 shell -- otherwise GHC make system would not recognize build triplet.
Cheers,
Kyra

Hello,
I am trying to compile GHC 7.8.3 on Windows. I was following the instructions from the GHC wiki, but I have encountered errors during the make process.
I have filed a bug report describing my issue: https://ghc.haskell.org/trac/ghc/ticket/9513
Does anyone had working setup for building GHC and would be willing to share information on how to achieve it?
