Installing gtk2hs failure

问题

I followed the instructions to install gtk library on Windows 8.1 x64 using http://wiki.haskell.org/Gtk2Hs/Installation.

I've installed MSYS2 and used it to download and build gtk. Then I've run:

cabal update // ok

cabal install gtk2hs-buildtools // ok

cabal install gtk // failed, 

cabal logs:

• glib.log

I am suffering from the same error message for the last two days and finally got a work-around (though I am using win7 -x64).

You need to download glib separately from https://hackage.haskell.org/package/glib. Then you need to adjust glib.cabal as described here: https://mail.haskell.org/pipermail/haskell-cafe/2015-October/121935.html (you have to remove the cpp-option: '-D__attribute__(A)=')

Finally, switch to your glib directory and run:

cabal install glib.cabal

This should work. You may have to do the same steps with the other gtk+ dependencies.
