Dear list, I am trying to install grapefruit on Kubuntu 14.04. Most of the dependencies seemed to install without incident, but I am running into the following error: jeff@jeff-Lenovo:~$ cabal install grapefruit-ui-gtk grapefruit-examples Resolving dependencies...

Any ideas?

Thanks guys! I found the library, though, as a .tar.gz file under /home/jeff/.cabal/packages/hackage.haskell.org/grapefruit-ui/0.1.0.5, and when I uncompressed that, found the UIItem file. I can't find the offending character in it, though. Supposedly it was at position 12.2 (line 12, column 2, right?), but I only see whitespace there. The first few lines of it are these ("module" being the first word of the first line): module Internal.UIItem ( -- * User interface items in general UIItem (UIItem), item, -- * Bricks Brick, brick, just, -- * Boxes Box, box, with, With (With), On Mon, Jan 5, 2015 at 2:00 PM, Brandon Allbery wrote:

I did not realize UIItem.hs and UIItem.hs-boot were separate things; I thank Matthew Pickering for pointing out that potential error in a private message. It looks like Alan or Kim was right: the 12th line of the boot file reads "#if MIN_VERSION_base(4,7,0)", and the file contains no mention of CPP. I am left with two questions: How to enable CPP? ------------------ Do I just include the following liine at the top of the boot file? {-# LANGUAGE CPP #-} How to replace the boot file? ----------------------------- In my hackage.haskell.org folder there are a lot of subfolders named after Haskell libraries -- arrows, cairo, etc. Almost every one of those includes in turn a single folder with a version number, and within that a .tar.gz file. In order to find the error you all helped me locate, I uncompressed the .tar.gz file in the grapefruit-ui folder. I could alter that object, but that does not seem likely to help, because I would not be altering the data that Haskell actually uses. Thanks! This is exciting!

Regarding replacing the boot-file, I thought I could delete the original .tar.gz file and replace it with one of my own. But that seems like it would only be a temporary fix -- would Cabal not discard that for a newer one every time I update, thus bringing back the problem?

Hi, Probably, the best solution in this case (and most similar cases) is to send patch to upstream. I believe, grapefruit maintainers will be glad to see it. As far as I know, you can open a bug at http://trac.haskell.org/grapefruit/. Mailing list is also a nice place to try: http://projects.haskell.org/cgi-bin/mailman/listinfo/grapefruit Regards, Alexey 2015-01-06 1:08 GMT+02:00 Jeffrey Brown :
