Haskell packaging on Windows "cygwin" (<< POSIX on Windows ; ^)
Hello, I trying to get a library to build ... I am following the instructions in http://en.wikibooks.org/wiki/Haskell/Packaging. Under the "Build your project" section in this web page, when I try to do an actual build (runhaskell Setup.lhs build), the imported module System.Environment cannot be found. I suspect that there is a "cygwin" ("Linux/Posix") environment variable that needs to be set to point to the Haskell libraries/packages. ?? Kind regards, Vasya
The message I actually receive is:
runhaskell Setup.lhs build ....
.....
./Haq.hs:6:7:
Could not find module `System.Environment':
it is a member of a package base, which is hidden
BTW I haven't actually checked source in via darcs due to cygwin $PATH
problems ...

Have you tried adding: build-depends: base you your .cabal file? Cabal enforces that your code may only use packages that you have explicitly stated your code depends on. Duncan
thank you everybody. my bad... a misspelling on my part ;^)
