Hi Mario,

Is the name of the module within the Shell.hs file Main? If not, that could be your problem. You may be right, the module's name is Shell, not Main. GHC does not have problem with that when "--main-is Shell" option is specified on the command line. Is Cabal different? Is this documented somewhere?

Cabal doesn't pass the --main-is option, I believe because it is specific to GHC. What you could do is add this flag in the ghc-options field of your executable in the cabal file, like this:

ghc-options: --main-is Shell

That worked like charm, except the two dashes should be one (my mistake). Thank you.
