Running “C:\msys64\msys2_shell.cmd -mingw64 -mintty" has the same effect as
clicking on the "MinGW-w64 Win64 Shell" shortcut. It is the proper way to start
an mingw64 shell.
Interesting. Most shells are started by ‘make’. I think it uses the SHELL
envt variable to decide what to start. Currently I have that set to
* c:/msys64/usr/bin/bash
Are you saying that I should put
* C:\msys64\msys2_shell.cmd -mingw64 -mintty
into my SHELL envt variable?
(Also: I always a shell within emacs, rather that an msys window, and it uses
SHELL to decide what to run.)
Also: is this related to the
export MSYSTEM=MINGW64
question?
Thanks
Simon

Hi Simon,
Running “C:\msys64\msys2_shell.cmd -mingw64 -mintty" has the same effect as
clicking on the "MinGW-w64 Win64 Shell" shortcut. It is the proper way to start
an mingw64 shell. If you have run "pacman -S" to update the MSYS2 packages
before, then the old shortcuts setup by the MSYS2 installer may cease to
function, and you can put a new shortcut on your desktop with that command.

Well I just followed the Method A instructions at
https://ghc.haskell.org/trac/ghc/wiki/Building/Preparation/Windows
Are you saying that I should run “C:\msys64\msys2_shell.cmd -mingw64 -mintty"
just once, after installing? Or repeatedly? Or that I should somehow us it as
my main shell? And what does that commend actually do?
Sorry to be dense

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
Simon
