I have seen the dreaded "ExitFailure 1" many times when a package fails to install (under Linux or Windows), and I wonder why something more helpful cannot be printed? Sometimes one gets a variant of this where the message is "this system is not compatible with this package," but the user must study the foo.cabal file to determine what is missing.
Also, it seems that the only way to determine if a package will install under Windows is to try and hope for the best (often getting "ExitFailure 1" if it fails). Wouldn't it make more sense to tag packages with the OS and other dependencies and fail with a helpful message like "Windows not supported" if appropriate?
A faster way to discover if a package can be installed on Windows: cabal install lens-4.1 --dry-run If the package depends on the package unix, it's not Windows compatible. This is of course not always sufficient, e.g. if you need to install non-Haskell software first.
