I am going to install hmake and upgrade to ghc 5 but in the meantime I decided to use make.
I am puzzled however. Presumably building a module that imports a module needs the .hi file and therefore the makefile should be something like this:
Tagsv1.o : Tagsv1.hs ghc -c Tagsv1.hs -package lang
Basev1.o : Tagsv1.hi Basev1.hs ghc -c Basev1.hs -package lang
But if I do this then make complains if I want to see what it will generate
[dom@lhrtba8fd85 maketest]$ make -n ghc -c Tagsv1.hs -package lang make: *** No rule to make target `Tagsv1.hi', needed by `Basev1.o'. Stop.
Running make works as by the time the rule gets executed the .hi file exists.
Can anyone suggest something better?
GHC's documentation has some useful tips on using make with Haskell: http://www.haskell.org/ghc/docs/latest/set/separate-compilation.html#USI NG-MAKE Chees, Simon
