Hi all, I am trying to prepare a new release of wxHaskell based on ghc 6.4 but I am in despair. It seems that the new package descriptions do no longer allow environment variables in there. For example: import-dirs:${wxhlibdir}/imports I would like the ${wxhlibdir} to be replaced by the value in the environment. This feature is absolutely *essential* to get the windows installer working. I use a batch file that gets the current directory and puts that in the environment before call ghc-pkg. On unix, I can use sed to make it work, but this does not hold for windows. What can I do to allow the user to install wxhaskell at arbitrary places using just a batch file? (ie. we can not assume that cygwin is available) I can hardly believe if no one has thought of this before, so I hope it is just a syntax issue. All the best, -- Daan. ps. If someone knows a solution, please tell me soon as this is my last day the university and thus my last opportunity to build a wxHaskell release on multiple platforms.
