I have a problem with Cabal: it doesn't seem to pick up the "Main-is:" option from the configuration file. Here's my "scc.cabal" file. Note the "Main-is:" line:
Name: scc Version: 0.1 Cabal-Version: >= 1.2 Build-Type: Simple License: GPL License-file: LICENSE.txt Copyright: (c) 2008 Mario Blazevic Author: Mario Blazevic Maintainer: blamario@yahoo.com Synopsis: Streaming component combinators
Executable shsh Main-is: Shell.hs Other-Modules: Foundation, ComponentTypes, Components, Combinators Build-Depends: base, containers, process, readline, parsec
Library Exposed-Modules: Foundation, ComponentTypes, Components, Combinators Build-Depends: base, containers
And below are the outputs of Cabal configure and build commands. Note the absence of "--main-is" ghc command-line option. I'm doing this on Ubuntu 8.04 Linux, but I get the same problem with Gentoo. Is there something wrong with my configuration file, or is this a bug in Cabal?
