Hi!
I've just installed ghc (v 6.10.1) for Windows, and it seems to be installed correctly, and now I'm trying to install Cabal (v1.6.0.2), but I'm getting the following error message (along with a lot of warnings about a deprecated something-or-other, which I assume I can ignore):
During interactive linking, GHCi couldn't find the following symbol: SHGetFolderPathA@20 This may be due to you not asking GHCi to load extra object files, archives or DLLs needed by your current session. Restart GHCi, specifying the missing library using the -L/path/to/object/dir and -lmissinglibname flags, or simply by naming the relevant files on the GHCi command line. Alternatively, this link failure might indicate a bug in GHCi. If you suspect the latter, please send a bug report to: glasgow-haskell-bugs@haskell.org
Am I missing a dependency, or is ghc not installed properly, or am I doing something else wrong?
As Andrea (and the README file) say you need to ghc --make Setup ./Setup configure --user ... etc The reason the first thing you tried did not work is due to: #325 SHGetFolderPath requiered to configure cabal on windows http://hackage.haskell.org/trac/hackage/ticket/325 The solution is for some Windows person to update the Win32 binding package to bind these functions, then we can import them directly rather than having to FFI import them ourselves (which does not work in ghci because we cannot tell ghci which extra dll libs are needed).
