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?
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.
Should I just try to set up everything piece-meal?
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.
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.
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.
Best, Irvin
