[Firstly, appologies if this is a duplicate, my first mail did not appear on the list.] Summary so far: I want to dynamic load haskell code into a host haskell application (plug-in style) I have, as suggested, put together an interface for Linker.h, and written some little wrapper functions. I have a few questions though... (is there any documentation?) What are the integer return values from loadObj/resolveObjs/unloadObj ? What is the void* pointer returned from lookupSymbol - and how do I apply it if its a function. (my first guess was to import rts_apply) Finally, when I load the module there are unresolved symbols - will it link against the main program? Is there any way to get it to do this? (I would like to avoid dynamic loading dependancies if the code is already used by the main program) Keean
