Re: [Haskell-cafe] "build depends:" in a .cabal file

Hello,

It seems to me that the "build depends" attribute/field is only informational, i.e. it doesn't cause "faulting in" dependencies if not present? If true, this seems to be a deficiency in cabal. ??

At least when compiling with GHC, Cabal exposes only packages which are mentioned under Build-Depends. That is, if a package is missing in Build-Depends, the project cannot be compiled. It is however possible to forget modules in the Exposed-Modules and Other-Modules section and GHC finds them anyway.
