pvolgger:
I tried following very simple program:
module Main where import System.Eval.Haskell
main = do i <- eval "1 + 6 :: Int" [] :: IO (Maybe Int) if isJust i then putStrLn (show (fromJust i)) else return () I compile it with "ghc -c Main.hs" and everything seems fine. When I run it with "ghc Main.o" I get following message: Main.o(.text+0x48):fake: undefined reference to `AltDataziTypeable_zdfTypeableInt_closure' Main.o(.text+0x4d):fake: undefined reference to `SystemziEvalziHaskell_eval_closure' Main.o(.text+0x36f):fake: undefined reference to `__stginit_SystemziEvalziHaskell_' Main.o(.rodata+0x0):fake: undefined reference to `SystemziEvalziHaskell_eval_closure' Main.o(.rodata+0x4):fake: undefined reference to `AltDataziTypeable_zdfTypeableInt_closure' collect2: ld returned 1 exit status
You'll need to use --make to link aginst the 'plugins' package. As in: ghc --make Main.hs
When I run it with "runhaskell Main" I get:
Won't work on windows. You're trying to dynamically link the dynamic linker, when using 'runhaskell'. (this is ok on ELF systems). -- Don
