Hmm, looks like you are building Hat 2.01 (from CVS), not 2.00.
nhc98 +RTS -K12M -H64M -RTS -cpp -c -o /Volumes/Apps/Install/nhc/targets/powerpc-Darwin-6.1/obj/hatlib/nhc98/TPreludeBuiltinTypes.o TPreludeBuiltinTypes.hs I/O error (user-defined), call to function `userError': Can't open any of: ./Hat.hi /usr/local/include/nhc98/Hat.hi when trying to read Hat.
Is it possible that there is an old Hat.o file hanging around, but you have removed the corresponding Hat.hi file (with `make clean' or similar?) Look for /Volumes/Apps/Install/nhc/targets/powerpc-Darwin-6.1/obj/hatlib/nhc98/Hat.o and delete it if you find it.
That is, I downloaded hat-2.00 and cvs checked out nhc, configured for compiling with nhc98 (which did install ok), then 'make hat'.
You are making Hat 2.01 inside the nhc98 tree, rather than Hat 2.00 from the separately downloaded stable version. My guess is that, in the CVS tree you did ./configure make # build nhc98 make install # install nhc98 make hat The final step probably failed with ..../script/hat-trans: Command not found and you guessed you needed something like ./hat-configure make clean make hat If you really want the CVS version of Hat, then I suggest you start again with make realclean ./configure # configure nhc98 (but we don't need to re-build it) ./hat-configure # configure Hat make hat ./hat-configure --install # install Hat - do not use 'make install'.
