Re: [Haskell-cafe] Ease of Haskell development on OS X?

Good to hear you're shipping graphical Haskell apps, Jefferson. Well done. We do have tools for packaging for various distros: * Mac OSX: http://hackage.haskell.org/cgi-bin/hackage-scripts/package/mkbndl * Windows http://hackage.haskell.org/cgi-bin/hackage-scripts/package/bamse * Linux http://hackage.haskell.org/packages/archive/pkg-list.html#cat:distribution * cabal-rpm * cabal2arch * cabalmdvrpm * hackport * hslackbuilder I'm not sure that anyone's attempted to write a tutorial on taking an arbitrary cabalized application, and generating shippable installers for the major systems, but we're close. bamse is used by Galois, afaik, for some of our windows applications. -- Don jefferson.r.heard:

As this continues to build, I guess the issue for me, and I'm willing to help with it, is trying to figure out how to redistribute programs written with gtk2hs. on Windows, people can just install the gtk2hs libraries via the installer -- although this does bork a little because it assumes you have a haskell compiler on the machine. Ignoring the errors, however, works. I don't see a similar situation on Mac OS.

If I wanted to package an application, which I often do, because firefighters, police officers, and emergency managers (my research currently targets these people, and we're actually beginning to really deploy our apps) don't have the time nor inclination to compile programs on their machines, I can basically just hope they're running windows. It'd be nice if there was a binary "redistributable" on windows that doesn't generate errors because of no haskell compiler installed and a similar package on OS X that includes the X11 Gtk binaries and precompiled Gtk2Hs binaries.

I guess I just don't know yet how to package things for OS X or find everything I'd need to find to build a redistributable image in the first place. I haven't yet drunk the coolade on the whole Mac development process, having sidestepped the normal process by being a Haskell developer. I'm sure they have standard procedures for finding and packaging libraries.

Ah, true. Sorry, my mistake -- I forgot that wasn't supported with the framework version.

That one doesn't work with OpenGL, however and won't in the forseeable future.    Incidentally, just now doing a ports install gtk2hs gives me the following error on my brand new MacBook:

While there is not a .dmg for Gtk2Hs, you can use a .dmg installed GHC with a .dmg installed Gtk, and then build gtk2hs straight on top of that, without having to deal with the dual-GHC macports mess..

cabal-install works for me.  The one thing that would be REALLY REALLY nice (and I'm cc-ing Duncan on this) is a .dmg for Gtk2Hs on Mac OS X. There exists a ports build for it, but it won't use the GHC that is installed via .dmg to build it - it insists instead on installing ghc again via ports, which I find both odd and undesirable.  It really comes down to the fact that gtk2hs is the only thing in the haskellverse that requires ports to get compiled in an intuitive way.

Yes, anything that is relevant to the development experience on this platform. Remember: it is more than just getting ghc. How do they get hold of new libraries and apps? Is cabal-install available? _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
