Hello cafe-subscribers, I saw some issues about installing haskell bindings for cURL under Windows, and now I'm trapped too. So, here is actions' log for everything (very detail; you can PgDn to the end with questions): 1. Windows Vista without UAC 2. ghc-6.10.1-i386-windows.exe is installed to C:\Program Files\Haskell "C:\Program Files\Haskell\package.conf" wasn't touched after installation (Cabal nor manually) 3. MinGW-5.1.4 installed to C:\temp\MinGW 4. MSys-1.0 installed to C:\temp\msys\1.0\ 5. curl-7.19.3.tar.bz2 had taken from http://curl.haxx.se/download/curl-7.19.3.tar.bz2 6.

I tried to use Cabal but it failed with building too. How can I test the fact that C:\temp\msys\1.0\local\bin\libcurl-4.dll is used in curl-1.3.4 ? -- Iliya Kuznetsov +7-916-878-75-70
