Hi,
there's a couple of things going on here:
* Makefile dependencies are not being computed
for the pcre/ sample.
To fix, reverse the ordering in HS_SRCS, i.e.,
have it say
HS_SRCS = Pcre.hs RegLib.lhs Main.lhs
* The parse error you're getting while processing
types.h is a bug in 0.16's parser - it doesn't
support prefix GNU attribute decls (which glibc
must have started using recently, since it used to
work just fine.) A fix is available via the CVS
repository.
If you need the fix & don't have access to CVS,
let me know.
* toInt/fromInt issues - if you're using a version
of GHC that supports this via GlaExts (as was the
case for 4.04pl0), you have to manually adjust the
generated Haskell source to use it instead of Int.
For people that use older versions of GHC (and Hugs),
there's the hdirect option -fint-prelude-coercions
to have it pick up toInt/fromInt via the Prelude.
