I'm dimly aware that we build this wxc library that wxcore is dynamically linked against (I think), that we seem to give this library a different name depending on what wxWidgets we build against (for example, on my Mac, I have libwxc-mac2.8.7-0.11.1.3.dylib, whereas on Linux, I have libwxc-gtk2.8.8-0.11.0.so), and that we tend to install this library in the same place that wxWidget's wx-config program lives (eg /usr/local/wxhaskell/lib on my Mac because I've symlinked wx-config into the /usr/local/wxhaskell/bin directory for convenience, but /usr/lib on my Ubuntu box (yuck!) because I forgot to do the same). I also know that somehow on my Mac the wxcore package has this information: library-dirs: /usr/local/wxhaskell/lib hs-libraries: wxcore wxcore0 wxcore1 wxcore2 extra-libraries: wxc-mac2.8.7-0.11.1.2 And I vaguely recall that this is due to some ghc-pkg specific file that we generate from our Makefile. I don't remember what these wxcore wxcore0 wxcore1 wxcore2 libraries are, unfortunately. > > Try it and see what I mean.

I'll take a look and write back. Are you starting to see what I'm getting at? I'm sorry if I'm being unclear; it's because I just don't have a good grasp on what all the pieces are and how they all fit together. I'll bet we can do things to make this simpler though. One hope was to be able to dissociate wxc from wxcore, but I don't even know if this is actually a good idea or potentially foolish. If we do this, then we're going to have to find some way for pick up this wxc library for linking whenever we build a wxHaskell program. Surely this sort of thing has been solved before by other Haskell libraries that wrap around some C library! -- Eric Kow <http://www.nltg.brighton.ac.uk/home/Eric.Kow> PGP Key ID: 08AC04F9
