I ported a little Haskell program I wrote from Mac to Windows. It’s a GUI application (wxHaskell, compiled with ghc 6.12.1), so it does not need the command prompt window to open. It does so, anyway, so my question: What must I do so that the program starts without opening a prompt window first? Is there some ghc switch for this?
When using wxWidgets with cygwin, you can avoid having a console window appear by passing the
-mwindowsflag to the linker. You can tell GHC to pass flags to the linker using the-optlprefix, so you could try building with-optl-mwindowsand see if that works.I’ve done that before when building a Haskell SDL application on Windows, and it worked for me. I think the
-mwindowsflag is cygwin-specific though, and I’m not sure what your install of GHC might be using as a linker.
