I am trying to install qtHaskell in Windows. I have Qt 4.8.4 (the Visual Studio 2010 version). I am following the section <<2.3.2 Windows Manual Installation>> from the userGuide of qtHaskell. I set the path as described I added the line to qt.cabal, I changed dir to qws I gave qmake -recursive and then instead of mingw32-make I gave nmake which is the equivalent for VS2010. After the compilation process finished with success I switched back to root directory of qtHaskell and I gave "runhaskell Setup.hs configure --ghc" and I took the message: "Setup.hs:1:12: Warning: -fglasgow-exts is deprecated: Use individual extensions instead Configuring qt-1.1.4... " After that I gave the command: "runhaskell Setup.hs makefile" and I got the message: "Setup.hs:1:12: Warning: -fglasgow-exts is deprecated: Use individual extensions instead unrecognised command: makefile (try --help)" Any help in order to continue? Thank in advance
