See what it thinks about the status of happy.
happy is a program. ghc-pkg doesn't know about it.
i'm having some difficulties compiling the 6.8.1 extralibs on a Mandriva 2007.0 box. Despite happy 1.15 being installed (with the happy binary in /usr/bin/), i get the following error:
Preprocessing library haskell-src-1.0.1.1... Setup: The program happy is required but it could not be found make[1]: *** [haskell-src/GNUmakefile] Error 1 make[1]: Leaving directory `/usr/src/ghc-6.8.1/libraries' make: *** [stage1] Error 2 Command exited with non-zero status 2
Any suggestions as to how to fix this would be greatly appreciated. :-)
Install happy from http://hackage.haskell.org/cgi-bin/hackage-scripts/package/happy-1.17 Note that happy 1.17 needs Cabal-1.2 and 1.16 needs Cabal-1.1.6. Alternatively, don't build the extralibs at the same time as ghc and install just the ones you need individually later. They're all available on hackage. Duncan
