I think you meant "if you want to create a static (.a) library", not "if you want to create a shared (.a) library" Those of you who have some experience with > Apple's gcc also know that Apple's gcc does not recognise the -shared > flag. > > (2) A much more aesthetic solution would be to replace any external > Bignum library with a pure Haskell library.
