Got and installed a lot of dependencies and the latest and greatest lhc in 20 minutes (may have been 21, I didn't time it with a stop-watch) again :) > > > Unfortunately: > > $ lhc -o lhcHeap heapMain > > lhc: user error (LibraryMap: Library base not found!) > > > > Oops. > > There is a reason this is happening, and there isn't an easy way to > get around it right now, it seems. > > The problem is that when you just install lhc, it has no libraries.

Scary thought, huh? :) Fair enough. Might be good to advertise that on Hackage, though. > > The easiest way to fix this problem is by doing the following: > > 1.

Though for some reason cabal --version says cabal-install version 0.6.0 using version 1.6.0.1 of the Cabal library even though I changed the constraint to Cabal >= 1.7 in the cabal-install.cabal file? > 4.

No extensions and libraries, just a bit of Haskell98, the implicit heap from http://www.haskell.org/haskellwiki/Primes with a main that prints the n-th prime. I wouldn't expect many extensions yet, but most of H98. > > Austin Cheers, Daniel _______________________________________________ Haskell-Cafe mailing list [email protected] http://www.haskell.org/mailman/listinfo/haskell-cafe
