Does anyone know how to create .a files for use with packages? I have the following situation:

A directory 'PACK' with a number of ghc-generated object (.o) files.

When I do the following:

$ ghc Test.o PACK/*.o -o Test

everything works fine. However, when I say:

$ cd PACK $ ar -rvs libPack.a *.o $ cd ..

And then do the following:

$ ghc Test.o -LPACK -lPack -o Test

GHC starts complaining about "warning: type and size of dynamic symbol `<ModuleName>_<FunctionName>_closure' are not defined". These are precisely the functions that the module Test is using.

Do you by any chance also have a libPack.so lying around? Cheers, Simon
