Well I tried this statement ghc --mk-dll -fglasgow-exts -fffi -I. --make ExternLib.hs
It only compiled the object file, creating ExternLib.o, but it did not create the stub file or attempt to link in the dependent packages. I then went back to this, ghc --mk-dll -fglasgow-exts -fffi -o netsim.dll ExternLib.o ExternLib_stub.o dllNet.o src1.o src1_stub.o src2.o -package parsec -optl-lmatrixstack -optl-L"." This removed the undefined references to the parsec package, however I still can't get it to link to the matrixstack.lib and matrixstack.dll. matrixstack.lib was created using dlltool and does link just fine if linking the sources into a stand alone executable instead of a .dll. I did try to include matrixstack.lib on the command line directly as well but that ended up with the same problem. Is it possible to just compile everything into C? I'd need to link to the haskell runtime libraries somehow.
