Re: [Haskell-cafe] ANNOUNCE: Haskell Pdf Presenter (hpdfp) 0.2.2

I have published a new version (0.2.3) to Hackage that should fix this build error. On Thu, Nov 14, 2013 at 2:29 AM, Michael D. Adams wrote:

I am compiling with GHC 7.6.1 (Ubuntu), Base 4.6.0.0, Cabal 1.16, glib 0.12.4, poppler 0.12.2.2, gtk 0.12.4, cairo 0.12.4 (all from Hackage).

The Hackage version of glib, etc. do not work with Cabal 1.18 due it adding 'moreRecentFile' to the API. However, it does seem to work if you downgrade the Cabal package to 1.16. It is any easy fix to rename the function to avoid the conflict, so I'm not sure why the package maintainers for glib, etc. haven't already done that.

If you make the following change does hpdfp build with ghc/fedora (distro package) 7.4.2? (If so, I'll upload a new version of the package with the patch.)

ANNOUNCE: Haskell Pdf Presenter (hpdfp) 0.2.2

could you explain how you compile this? (what compiler, what version of base, etc.)

For me, it does not work with ghc-7.6.3 (binary package) because gtk2hs does not work hackage version (0.12.4) does not work because of /tmp/gtk-0.12.4-7461/gtk-0.12.4/SetupWrapper.hs:94:45: Ambiguous occurrence `moreRecentFile' and darcs version (0.12.4.1) breaks with Graphics/UI/Gtk/Printing/PrintOperation.chs:409:6: Couldn't match expected type `Ptr ()' with actual type `Window'

and it also does not work with ghc/fedora (distro package) 7.4.2 HaskellPdfPresenter.hs:901:10: Ambiguous occurrence `catch' It could refer to either `Prelude.catch', imported from `Prelude' at HaskellPdfPresenter.hs:1:1 (and originally defined in `System.IO.Error') or `Control.Exception.catch',
