[Haskell-beginners] how to save the GHC errormessages in a file on Windows

When I try in Windows in cmd: ghc --make myprogram.hs > test.txt I only get the first lines in test.txt. The errormessages itself are on the screen, not in test.txt. In test.txt: Resolving dependencies... Configuring ftphs-1.0.7... Preprocessing library ftphs-1.0.7... Preprocessing executables for ftphs-1.0.7... Building ftphs-1.0.7... The errormessages: Could not find module 'Network.FTP.Client'.... and a lot more. How do I 'intercept' these messages? Kees
