$ hmake -T -hat -package util -package hat Dicedist
First of all, the -T option and the -hat option are mutually exclusive: * use -T with hmake -nhc98 * use -hat with hmake -ghc Secondly, the "-package hat" option is unnecessary, because hmake adds it automatically where it is needed.
My program uses the GetOpt module from the util package in ghc
Right. You can build a tracing version of any library for which you have the source code (and which is Haskell'98 compliant), but at the moment it is impossible to trace a library when the source code is not directly available to the compiler. We have made a special exception for the Haskell'98 Prelude and Libraries, because these are part of the language standard, but we do not supply pre-built tracing versions of any of the other libraries in the GHC package system, for two reasons: * there are so many of them, and we have only just started to support tracing with ghc * we aren't yet sure how to use/abuse GHC's package system to ensure that the tracing versions are available under the same names, even though the code is different As it happens, I believe the GetOpt library is Haskell'98 compliant, so the simplest solution for now is just to find a copy of the source code for it, and place it in the same directory as your program. (But you may need to remove it again when you build your program normally without tracing.) Regards, Malcolm
