Hi
I'm having trouble installing Haskell platform using Ubuntu (Karmic
Koala).  When I run ./configure I get the message

configure: error: The Haskell Platform version 2010.1.0.0 requires
ghc-6.12.1  It is recommended that you upgrade to ghc-6.12.1 however
if you really want to use this release with an unsupported version of
GHC then use ./configure --enable-unsupported-ghc-version

In synaptic the latest version of ghc is 6.10.xx; I've tried doing
./configure --enable-unsupported-ghc-version, but make fails to set up
Cabal.
Any suggestions?  Should I just try to set up everything piece-meal?
Do I need to remove the currently installed version of ghc using
synaptic before I try to use the 6.12.1 installer or build it from
source.  Thanks.
Best,
Irvin

You can just download and install the binary version of 6.12.1 from
the GHC website [1]. It will stick the GHC binary and libraries under
/usr/local. This shouldn't interfere with Karmic which installs it to
/usr/ and '/usr/local' is usually first on the search path.

Once you have your compiler installed Haskell Platform should be a breeze.

Once everything's working you can then delete using Synaptic.

BTW I know that other people on this list differ but I think
installing any Haskell-related packages using apt-get is a bad idea.
Cabal is so easy that it makes apt-get obsolete.

You could use the previous version of the platform, which was for 6.10.x.

Perhaps there's a 6.12.1 in debian unstable, IIRC, Ubuntu uses debian 
packages, so you could install that then.

Or you could build 6.12 from source.

Or that. Install just the packages you actually use. That worked before the 
platform, it will continue to work, though getting a comprehensive set of 
libraries is a bit more inconvenient.

If you build from source, you need a working GHC installed, so no.
Don't know about the binary, but usually there's no problem having multiple 
versions of GHC at once, so probably you don't need to uninstall anyway.
