Hi "hat guys", I have a problem: I try to get hat installed under Mac OS X and so I have it now under /opt/local/ with the help of Darwinport (a rpm file could be installed, or rather forced into this location using a rpm2cpio.sh script). I should say that I also have a ghc installation in fink /sw/bin/ghc (6.2), and *also* one under /opt/local/bin/ (6.4). I have set the GH library path and given the /opt/local precedence in the $PATH variable, so I really hope this is not the problem (well it works for usual Haskell files anyway). Despite this, I cannot get hat up and running. The problem is probably not hat, since the hat-trans compiler seems to work just fine. The problem is to use ghc on the result: $ ghc -v Hat/myresult.hs Using package config file: /opt/local/lib/ghc-6.4/package.conf ... Failed to load interface for `Hat.PreludeBasic': Could not find module `Hat.PreludeBasic': locations searched: Hat/PreludeBasic.hi Hat/PreludeBasic.hi-boot I guess my installation is somehow corrupt, but I wonder if I can manually add Hat to package.conf to avoid this problem. Note that hat resides in /opt/local/bin /opt/local/lib/hat /opt/local/include/hat hmake works fine without hat at the moment, but with the -hat argument I get similarly: $ hmake -hat myfile.hs ... ghc -c -package hat -o ... ghc-6.4: unknown package: hat Many thanks to some help to get 'hat' up and going!
