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

[Aditya Siram]

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...

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.

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

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.

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

[Aditya Siram]

Hi all,
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:
