I'm putting together a package consisting of 2 executables. Only one of them is pure Haskell and thus buildable on all platforms, the other relies on Windows API calls and can only be built on that platform. I

problems getting it to do what I want.
if os(mingw32) executable foo ...
Results in the error â Section expectedâ . Swapping the two lines like this
executable foo if os(mingw32) ...
results in â Setup.hs: Error: No 'Main-Is' field found for executable fooâ .
It sounds like another instance of the case that parts of a package cannot be build under some circumstances. Keep in mind that other packages might rely on the installed second executable if they find that the package is installed. Thus, I guess it's better to extract the second executable to a different package for Window's only stuff.
Good point. Does CABAL 1.2 have support for multiple .cabal files in the same directory? If not then I'm not too happy with this solution. /M
