Re: Windows

Hi Simon, If the build environment is managed by an MSYS2 installation, then the MinGW64 shell startup script automatically sets up "MSYSTEM" for you. It can be launched like "C:\msys64\msys2_shell.cmd -mingw64 -mintty". On Mon, Mar 26, 2018 at 5:46 PM, Simon Peyton Jones via ghc-devs < ghc-devs@haskell.org> wrote:

Making it part of the error message would be v helpful.

I have added a section to "Troubleshooting" on https://ghc.haskell.org/trac/ghc/wiki/Building/Preparation/Windows

But it should really be part of the instructions higher up to sa export MSYSTEM=MINGW64

Might someone do that? I wasn't quite sure where
