[Haskell-beginners] help designing types for a gsl fit

[Agustin Larreinegabe]

Hello,
I'm trying to install an application Termite - Debug
<https://raw.githubusercontent.com/termite2/debug/master/Debug/SourceView.hs>
but
I get this error in line 929:14

when it try to do this



             lprog <- G.labelNew Nothing


The error says:

Could not deduce (glib-0.13.4.1:System.Glib.UTFString.GlibString string0)
arising from a use of ‘G.labelNew’ from the context (D.Rel c v a s) bound
by the type signature for sourceWindowCreate :: D.Rel c v a s =>
RSourceView c a u -> IO G.Widget at Debug/SourceView.hs:913:23-73 instance
glib-0.13.4.1:System.Glib.UTFString.GlibString [Char] -- Defined in
‘glib-0.13.4.1:System.Glib.UTFString’ In a stmt of a 'do' block: lprog <-
G.labelNew Nothing In the expression: do { vbox <- G.vBoxNew False 0;
G.widgetShow vbox; spec <- getIORef svInputSpec ref; code <- codeWinNew
spec; .... } In an equation for ‘sourceWindowCreate’: sourceWindowCreate
ref = do { vbox <- G.vBoxNew False 0; G.widgetShow vbox; spec <- getIORef
svInputSpec ref; cabal: Error: some packages failed to install:

I really don't know how to proceed, I'm new with Haskell


Thanks in advance.
