Re: [Haskell-cafe] Newbie; Can't Install Hat From Source

Thanks to Malcolm Wallace I got Hat installed and working from darcs using: 'darcs get http://darcs.haskell.org/hat' cd'ing in to the 'hat' directory and doing an 'sh start'. This last step makes all scripts executable. Appreciate the support... Deech

I have been trying to install Hat for the last couple of days but GHC does not recognize it as a package. I compiled 2.05 from source, but at the 'make install' step I see this error message:

Installing hat package for ghc under /usr/local/lib/hat-2.05/ix86-Linux/ghc-606 ghc-pkg: cannot find package hat <-----ERROR MESSAGE!!!!!

This error message can be safely ignored - it comes from a requirement to support several different versions of ghc, each of which has a different interface to the package manager ghc-pkg.

...

ghc-pkg: package hat-2.4 is already installed

/usr/local/lib/ghc-6.6/package.conf: ... /home/deech/.ghc/i386-linux-6.6/package.conf: (hat-2.4) <----ERROR!!!

For some reason it thinks that hat-2.4 is installed.

This is one of a couple of bugs in the 2.05 package. The .cabal file simply had the wrong version number in it.

...

Bad interface file: /usr/local/imports/hat-2.05/ghc-606/Hat/PreludeBasic.hi Something is amiss; requested module hat-2.4:Hat.PreludeBasic differs from name found in the interface file hat:Hat.PreludeBasic

And this is the other bug: the Hat library package was built using "-package-name hat" instead of "-package-name hat-2.05" (as now required by ghc-6.6 and above).

I have re-rolled the Hat-2.05 distribution package with these two very minor bugfixes. Please try downloading it again, and re-building.
