[Haskell-cafe] "plugins" fails on a simple example

[Petr Pudlák]

Hi,

I'm playing with "plugins", trying to evaluate a simple expression:

|import  Control.Monad
import  System.Eval.Haskell

main  =do
    let  fExpr ="1 + 2 :: Int"
    r <- eval_ fExpr ["Prelude"] [] [] []
            ::IO  (Either  [String] (Maybe  Int))
    case  rof
        Right  (Just  f)  ->do
            print $ f
        Left  err -> putStrLn $"Error:"  ++ unlines err
        _ -> putStrLn $"Unknown error."|

However, it fails with

|Error:
on the commandline: Warning:
    -fglasgow-exts is deprecated: Use individual extensions instead|

Am I doing something wrong? How can I turn off the flag?

I'm using GHC 7.6.3.

Thanks,
Petr
