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. Tope

GHC Extensibility
by Monique Monteiro 03 Jun '07

03 Jun '07

Hi (this message is mainly intended to the GHC Team), is there any plan to improve GHC's extensibility by providing a simpler way to integrante new backends? I worked at Haskell.NET project in the past, when we integrated successfully a .NET code generator to GHC 6.2.2. As it wasn't stable enough, we didn't integrate it to the main branch. However, I've been trying to integrate our code generator to 6.6.1 and I've not been able to compile it up to now, due to several changes in GHC's code! I haven't yet figured out how to call the .NET code generator from GHC 6.6.1's main function. Further, it would be great if there was a better extensibility mechanism (such as a "plugin" infrastructure, for example) in which it wasn't necessary to use "#ifdef"along the code. Also, it would be very useful if this mechanism/API was well documented. Of course, this is only a suggestion.
