If you check existing archive loading mechanics in GHCi it doesn't look for `.lib` files either. Those files are usually produces by MSVC compiler which its not officially supported by GHC as far as i know.
I'm not sure what you mean by "not officially supported". Specifying .lib files + DLL files has always been the standard way to use FFI for third party libraries on Windows.
I think preferable way of getting libraries on Windows should be MSYS2 anyway as it uses the same compiler as GHC and already comes with really big collection of packages.
MSYS2 is very nice, but its "really big collection of packages" is insignificant compared to the amount of libraries compiled with MSVC and available as lib + DLL. And that's just open source - for proprietary libraries that commercial users of GHC need to link against, MSVC is basically the only option. Mingw is designed to support those, and it has always worked fine in the past. MSYS2 is a rock-solid option, when it's available. And we were grateful for that for {{{text-icu}}}. But is seems to me that it will always be a fallback. The normal way to link to a third-party library on Windows is with .lib files and DLLs. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11072#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
