I have installed Msys2 on Windows. In Msys2 I have installed Emacs, which I start with a custom cmd script with following environment variables set:

{{{ SET PATH=C:\msys64\mingw64\bin;C:\msys64\usr\bin;%PATH%

set XDG_DATA_DIRS=c:/msys64/mingw64/share set PKG_CONFIG_PATH=c:/msys64/mingw64/lib/pkgconfig set INCLUDE=c:/msys64/mingw64/include }}}

The haskell I have is from Full Haskell Platform, https://haskell.org/platform/download/8.2.1/HaskellPlatform-8.2.1-full- x86_64-setup.exe

Then I started eshell which I used to invoke this command:

{{{ cabal install gi-gtk }}}

Which after a while gave me following error.
