One other thing. The instructions at
https://ghc.haskell.org/trac/ghc/wiki/Building/Preparation/Windows
say to set PATH thus
export PATH=/mingw64/bin:\$PATH
But
* in the installation tree I got from msys, there IS no c:/mingw64/bin.
* I have a root directory c:/msys64.
* Most binaries (eg bash, find) seem to be in c:/mingw64/usr/bin
* But there is also c:/msys64/mingw64/bin, which (perhaps as a result of the pacman step) has lots more stuf like ar, cc, etc.
All very confusing. For now I have put both c:/msys64/usr/bin and c:/msys64/mingw64/bin in my path. That seems to work, but is clearly not what the instructions say.
Thanks
Simon

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".

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
