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!
