Re: [Haskell-beginners] Compiling Test.hs from reactive-fieldtrip

The .hs isn't necessary either. Here's the real answer: you simply need to add a -main-is flag to tell ghc that the module containing 'main' is not called 'Main'. So: ghc --make Test -main-is Test should do the trick. -Brent On Wed, Jun 09, 2010 at 03:47:55PM +1200, Stephen Blackheath [to Haskell-Beginners] wrote:

Nathan,

You must put the .hs on the input filename, but the '-o Test' isn't necessary. So you can type

ghc --make Test.hs

I took a look at this file, and the module name is 'Test'. If you change it to 'Main' it should work. I think this requirement was tightened up in newer versions of ghc.

Hey,

Thank you for the answer. Now I get:

ghc --make Test -o Test Warning: output was redirected with -o, but no output will be generated because there is no Main module.

How am I supposed to comple this file?

To compile an executable, tack on -o , so for instance, ghc --make HelloWorld.hs -o HelloWorld

creates an executable called `HelloWorld'. -deech

Hi,

I am trying to compile the Test.hs form reactive-fieltrip. I did: ghc --make Test (22:09) [1 of 3] Compiling FRP.Reactive.FieldTrip.Adapter ( FRP/Reactive/FieldTrip/Adapter.hs, FRP/Reactive/FieldTrip/Adapter.o ) [2 of 3] Compiling FRP.Reactive.FieldTrip ( FRP/Reactive/FieldTrip.hs, FRP/Reactive/FieldTrip.o ) [3 of 3] Compiling Test ( Test.hs, Test.o )

Wonderfull, only it is not giving me an executable, only Test.o.

It has a main function, so how can I compile it? Thanks! nathan _______________________________________________ Beginners mailing list Beginners@haskell.org http://www.haskell.org/mailman/listinfo/beginners
