I'm running Haskell Platform 2011.2.0.1 on a MacOS 10.6.7 machine (the machine is 64-bit, but I'm running the 32-bit platform). I'm writing an application for personal use, and I'd like to use Cabal to package it up and handle installation. This way, when I'm working on the program, I won't break the reasonably stable installed version and can continue to use it. (I'm not committed to cabal by any means; suggestions for other ways to accomplish the same thing are more than welcome!) I've got some data files I'd like to package with the application, and Cabal's data-files field is the obvious way to do that. The immediate problem, then, is how to access the files -- I can use the generated Paths_pkg module for the "installed" copy of the app, but then I can't run the thing in-place in ghci in the development directory. I did some googling and came across a blog post (http://neilmitchell.blogspot.com/2008/02/adding-data-files-using-cabal.html) which suggested that I provide my own Paths_pkg.hs file that points to the files' location in the development copy. When I build with Cabal, the generated form of this module would override my hand-written one, and it should therefore work in the installed case as well. Unfortunately, that's not happening. Cabal is clearly generating the module; I can see it in dist/build/autogen. But my copy is overriding the autogenerated one, even for cabal builds -- at least, that's what I'm seeing when I run the binary out of dist/build/<package>/<executable>. Is there a way to be able to use data files in both contexts? FWIW, I'm running cabal as runhaskell Setup.hs configure --user runhaskell Setup.hs build Thanks much, Richard
