Re: [Haskell-beginners] Getting Gtk2Hs working in windows

I got Gtk2Hs installed finally, although I'm not happy with at least one step of the process. First of all, the process outlined on the wiki is incorrect, in that the glade installer apparently does not come with everything you need in order to build the gtk module. Downloading the dev gtk all in one bundle off the gtk site gets you most of the way to a working install. It appears the environment variables mentioned in the wiki are also slightly off. You need to set the following: GTK_HOME: Location you unpacked the gtk all in one bundle to. INCLUDE: %GTK_HOME%\include LIB: %GTK_HOME%\lib PATH: %GTK_HOME%\bin PKG_CONFIG_PATH: %GTK_HOME%\lib\pkgconfig Furthermore at least in the configuration I have it appears that running "cabal install gtk" will fail. Instead you need to run "cabal install gtk --global", and you need to make sure that the cmd prompt you run it from is running with administrator permissions. I haven't gotten the glade bindings installed yet, but that should only be a matter of time. Most likely I'll have to go grab some other dev package off the gtk site. -R.

Yes, I read the thread you made. Working on a hunch I downloaded the Gtk+ all in one bundle and installed it but used all the environment variables defined by the glade installer (I just changed GTK_HOME to the newly downloaded all in one bundle and updated the other variables as needed). This seems to have fixed the libraries not being found, but it now looks like I'm being bitten by another issue entirely. I'm getting the following error: Registering cairo-0.12.0... Installing library in C:\Users\Kyle\AppData\Roaming\cabal\cairo-0.12.0\ghc-7.0.2 Registering cairo-0.12.0... setup.exe: internal error: unexpected package db stack: [UserPackageDB]

What's weird is that I found a ticket for cabal that's similar to this one (http://hackage.haskell.org/trac/hackage/ticket/731) but it's specifically in the case of using a custom package db which I don't think I'm doing (unless the gtk package is doing something really weird). Maybe this is a more general issue with the latest version of Cabal? Just in case the output from running cabal --version:

cabal-install version 0.10.2 using version 1.10.1.0 of the Cabal library

I'm going to keep experimenting and hopefully find a way to get this all working.

Hi Kyle, I ran into this exact issue and fixed it on my Windows box at work but I forgot how. I won't be back there till Monday, can I get back to you then?

If this is still an issue could send me email on Monday morning to remind me?

thanks... -deech

I'm trying to follow the instructions provided on http://www.haskell.org/haskellwiki/Gtk2Hs to install Gtk2Hs in Windows 7 (64 bit) and running into problems. Originally I was trying to get wxHaskell installed, but it kept crashing trying to build the monolithic library due to an apparent bug in the latest port of GCC, so after talking with some of the people in #haskell I was advised that Gtk2Hs was better supported and might be easier to get working. For the most part, that appears to be true but I (as well as several others it seems) am running into a problem where cabal can't seem to find quite a few of the Gtk+ libraries (specifically z, cairo, gobject, glib, and intl). Near as I can tell everything should be functioning, and running

--modversion glib-2.0 outputs "2.20.3" so at least pkg-config seems to be able to find glib. Looking in the Gtk+\lib\pkgconfig folder I see pc files for everything but z and intl listed. Running cabal install gtk2hs-buildtools also succeeds, it's only when I get to the cabal install gtk step that things fail.

cmd console output for the usual environment variables:

I trimmed the PATH output below for everyones sanity. The vast majority was stuff in the Windows folder or one of dozens of entries dumped in there by some version or other of Java.
