I am very new to Haskell, and I am using this webpage as a learning source: http://www.haskell.org/haskellwiki/Haskell_in_5_steps#Install_Haskell
I downloaded and instal GHC and it works as was said.
I tried to write my first Haskell program:
prelude> "Hello World!" "Hello World, World!"
it works as said.
Then: (This is the problem)
I would like to create a source code and compile it using GHC compiler. I opened a notepad and type this program:
main = putStrLn "Hello, Word!"
I saved this file as hello.hs in the same directory GHCi 6.6.1 was installed.
When I tried to compile it as instucted on the webpage ( $ ghc -o hello hello.hs), I got this error message.
<interactive>: 1:0: parse error on input '$'
please what am I doing wrong.
Thank you and sorry for your time.
Three things: 1. The $ is just a sample prompt, a convention used to indicate what you should typed. 2. The command is for a shell (CMD or COMMAND), not GHCi. 3. The command is wrong! for Windows it should be "ghc -o hello.exe hello.hs". Assuming you aren't knowledgable yet on the differences between Windows and Unix programming environments, it might be a good idea to pick another tutorial. Stefan
