I'm trying to do the following from Chapter 5 of "Real World Haskell": Our choice of naming for the source file and function is deliberate. To create an executable, *ghc* expects a module named Main that contains a function named main. The main function is the one that will be called when we run the program once we've built it. 6 commentscomments:%20show%20/%20hide *ghc -o simple Main.hs SimpleJSON.o* ---from http://book.realworldhaskell.org/read/writing-a-library-working-with-json-da... When I do that, I get this error: C:\ch05>ghc -o simple Main.hs SimpleJSON.o [2 of 2] Compiling Main ( Main.hs, Main.o ) Linking simple.exe ... SimpleJSON.o:fake:(.data+0x0): multiple definition of `SimpleJSON_getArray_closure' .\SimpleJSON.o:fake:(.data+0x0): first defined here SimpleJSON.o:fake:(.text+0x54): multiple definition of `SimpleJSON_getArray_info' .\SimpleJSON.o:fake:(.text+0x54): first defined here SimpleJSON.o:fake:(.data+0x4): multiple definition of `SimpleJSON_getObject_closure' .\SimpleJSON.o:fake:(.data+0x4): first defined here What's going wrong here?
