L.S., I am trying to install SDL-ttf: SDL-ttf-0.6.2>cabal install : : Preprocessing library SDL-ttf-0.6.2... dist\build\Graphics\UI\SDL\TTF\Version.hs:1:1: File name does not match module name: Saw: `Main' Expected: `Graphics.UI.SDL.TTF.Version' Failed to install SDL-ttf-0.6.2 : The error message is caused by the fact that Version.hs is empty; there is however a file dist\build\Graphics\UI\SDL\TTF\stdout.txt that contains the contents of Version.hs; there is also a file dist\build\Graphics\UI\SDL\TTF\Types.hs that is empty. These files are generated from Version.hsc and Types.hsc, in directory Graphics\UI\SDL\TTF How can this occur? Any way to debug this?
