Don Stewart:
Is there a Mac OSX packaging team?
Unfortunately, it's not just a packaging problem. (Well, packing of
Haskell libraries, that is.)
There are two version of GTK+ Mac OS X: (1) the MacPorts version and
(2) a native GTK+ framework.
Unfortunately, both are not satisfactory. The MacPorts version is
based on X windows, which is supported on Macs right out of the box,
but to be honest, X programs on the Mac are ugly and annoying.
Moreover, whether the MacPorts version builds at all seems to be a
matter of luck - I have been out of luck more than once. MacPorts is
also pretty useless once you want to distribute your GTK-GUI programs
to other Mac users.
The native GTK+ framework is a port of GTK+ to the native Mac GUI and
dead easy to install (it has a binary installer). Unfortunately, it
lacks many of GTK+'s optional components (most notably libglade). It
is however in beta right now, so we can only hope that there will be
more of the optional components in the final version.

Awesome! I want to try this.
I have problems though installing it on an Intel MacBook running
$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 6.10.1
$ cabal --version
cabal-install version 0.6.2
using version 1.6.0.2 of the Cabal library
$ ghc-pkg list gtk
/Library/Frameworks/GHC.framework/Versions/610/usr/lib/ghc-6.10.1/./
package.conf:
gtk-0.10.0
I have installed gtk2hs using the instructions at
http://www.haskell.org/haskellwiki/Gtk2Hs#Using_the_GTK.2B_OS_X_Framework
A simple cabal update; cabal install vacuum-cairo gives me:
$ cabal install vacuum-cairo
Resolving dependencies...
cabal: cannot configure vacuum-cairo-0.3.1. It requires svgcairo -any
There is no available version of svgcairo that satisfies -any
I have installed libsvg-cairo using MacPorts and it seems installed
in
/opt/local/lib:
$ ls /opt/local/lib/libsvg-cairo.*
/opt/local/lib/libsvg-cairo.1.0.1.dylib
/opt/local/lib/libsvg-cairo.1.dylib
/opt/local/lib/libsvg-cairo.a
/opt/local/lib/libsvg-cairo.dylib
/opt/local/lib/libsvg-cairo.la
But cabal-install still gives the same error. Even with --extra-lib-
dirs
set:
$ cabal install --extra-lib-dirs=/opt/local/lib/ vacuum-cairo
Resolving dependencies...
cabal: cannot configure vacuum-cairo-0.3.1. It requires svgcairo -any
There is no available version of svgcairo that satisfies -any
Hence, I downloaded the tarball and tried to use this instead to
install
vacuum-cairo, which lead to another problem: I cannot install the
vacuum
package because of a dependencies conflict due to the package
ghc-6.10.1
requiring two different versions of process:
$ cabal install vacuum
Resolving dependencies...
cabal: dependencies conflict: ghc-6.10.1 requires process ==1.0.1.1
however
process-1.0.1.1 was excluded because ghc-6.10.1 requires process
==1.0.1.0
Funny.
Any ideas on how to get this cool package installed?
Thanks!
Sebastian
