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: [EMAIL PROTECTED]
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?
