Hi everybody,
Everytime I want to compile a Haskell .hs file with Ghci, it fails as shown in the picture.
please I need help, I'm a newbie!!

aaa another thing may be in relationn, here is the source code of the file

import Graphics.Rendering.OpenGL
import Graphics.UI.GLUT
 
main :: IO ()
main = do 
  (progname, _) <- getArgsAndInitialize
  createWindow "Hello World"
  displayCallback $= flush
  mainLoop

ghc is a command line utility to compile haskell source code

ghci is the haskell interpreter

jason@db-box:~/haskell$ cat cc.hs
import Graphics.Rendering.OpenGL
import Graphics.UI.GLUT

main :: IO ()
main = do
(progname, _) <- getArgsAndInitialize
createWindow "Hello World"
displayCallback $= flush
mainLoop
jason@db-box:~/haskell$ ghc --make cc.hs
[1 of 1] Compiling Main ( cc.hs, cc.o )
Linking cc ...

If instead of compiling the code you want to run it through the inerpreter then just load it up into ghci

jason@db-box:~/haskell$ ghci
GHCi, version 6.12.1: The Glasgow Haskell Compiler :? for help
Loading package ghc-prim ... linking ... done.
Loading package integer-gmp ... linking ... done.
Loading package base ... linking ... done.
Prelude> :load cc.hs
Ok, modules loaded: Main.
Prelude Main>

ok, thank you,
there is another issue i'm dealing with, after compiling and running the .exe file, I end up with a dll missing file called "glut32".
So Thanks in advance....

Might need to install the haskell glut binding. It seems like you're using windows?
I don't know how to do it on windows on linux I just use cabal but I found this from hackage
