So, by default, cabal wants to put its config and updates on C:.

I looked at C:\Documents and Settings\pschmitz\Application Data\cabal\config

It has various references to C:, some commented out. E.g.:

remote-repo-cache: C:\Documents and Settings\pschmitz\Application Data\cabal\packages

build-summary: C:\Documents and Settings\pschmitz\Application Data\cabal\logs\build.log

install-dirs user -- prefix: "C:\\Documents and Settings\\pschmitz\\Application Data\\cabal"

You can change these to whatever you want, and cabal should just start using those locations, if that helps.

Given that I want to keep everything on H:, and assuming that I don't want to place the Cabal configs and updates in the Platform tree (H:\proc\tools\Haskell Platform), I would _like_ to create a dir such as H:\proc\tools\cabal to hold everything that Cabal would normally put on C:.

*** I'm afraid I'm having trouble figuring out how to accomplish this.

Is there (hopefully) a combination of cabal command line switches that will create a new config file over on H: for me, or must I edit the config file directly and move it to H:?

There are others on this list that know cabal much better than I, but I have been working with it a bit recently, so I'll take a stab.. I don't believe you can configure *cabal* to look on H: for the cabal config, without specifying . I believe it uses the windows Application Data directory for your current user to locate the cabal config (there is a windows system (?) call that returns something akin to c:\Documents and Settings\username\Application Data\ ). You *can* change the location of your Application Data directory by hacking the windows registry, but that is likely to cause more pain than it is worth. I think you will be best served by just editing the entries in your cabal config (if that, even) unless you have a very good reason to relocate the cabal config itself. (Ok, so I think I lied a little -- iirc, there is an undocumented cabal flag that will let you specify the path to the cabal config file to use. I think it has to be the first parameter to cabal, and I think it's --cabal-config=<file>, but I've only used it once and I don't think it's really worth the trouble in your case. Application Data is a pretty standard place for things like this.) --Rogan

I will try experimenting with editing the config file and using that hidden option you mentioned.

** Cabal experts:

If anyone knows how to do this sort of thing in a better way, I would appreciate a word.

Rogan is right. You just need to edit the cabal config file to point to locations on your other drive. I would suggest not relocating the config file itself. If you really must do so then you can use the --config-file flag or the environment variable CABAL_CONFIG. Duncan

I have a question about finding the Gtk2Hs demos (the demos written in Haskell). To summarize what I have done so far: I'm a new Cabal user; need to use Cabal in a Windows XP environment, where it and the Haskell Platform are located on a network drive (H:) instead of C:. (Need to be able to do development on any of several PCs, using a single tools dir.) I want to write Haskell code that uses Gtk2Hs (and Glade). I have edited Cabal's config and placed it on H:, and so I have set up: H:\proc\tools\Haskell Platform H:\proc\tools\gtk H:\proc\tools\cabal etc. My edited Cabal config is listed at the end below. I modified my PATH, etc. as follows: SET P_TOOLS=H:\proc\tools SET HASK_PLAT=%P_TOOLS%\Haskell Platform\2010.1.0.0 PATH %HASK_PLAT%\bin;%P_TOOLS%\cabal\bin;%P_TOOLS%\gtk\bin;%HASK_PLAT%\lib\extralibs\bin;%HASK_PLAT%\mingw\bin REM This is so Cabal will get its config from the Haskell Platform, REM rather than C:\Documents and Settings\pschmitz\Application Data\cabal SET CABAL_CONFIG=%P_TOOLS%\cabal\config I had to add the mingw\bin dir to PATH to get cpp (needed during "cabal install gtk"), and the extralibs dir to get alex (for "cabal install gtk2hs-buildtools"). I download the GTK+ "All-in-one bundle" 2.20.0 (current maintained branch), and ran gtk-demo; it works. The following commands then completed okay, with various warnings, but no fatal errors: cabal install cabal-install cabal update cabal install gtk2hs-buildtools cabal install gtk (There seems to be no "cabal install gtk2hs".) *** At this point I am trying to find the Gtk2Hs demos, so I can compile and run them. I cannot find them anywhere in my "H:\proc\tools\" tree. If anyone can help me see what I am missing, I would appreciate it. http://code.haskell.org/gtk2hs/INSTALL says: "To get started, you can compile and run one of the programs that reside in the demo/ directory in the respective packages. For example: ~/gtk2hs/gtk/demo/hello:$ make". But I don't see a "gtk2hs/" dir anywhere. I tried looking for the sources directly (google "gtk2hs demos", etc.) but didn't have any luck.

They're not there: http://osdir.com/ml/haskell-cafe@haskell.org/2010-07/msg00724.html

Ivan: Because I am a new Cabal user, I thought I was misusing it somehow, so that's why I included all the info. I found the demos and they compile and run fine. Thanks very much.
