Is this warning cause for concern? Everything appears to work as expected despite this hiccup. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15234 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

So it seems the solution should be to make the functions that look up plugin locations, within `mkPluginUsage`, work correctly on Windows. The only relevant files that I can see on my machine are static `.a` files. For instance, instead of the non-existent `libHSghc- typelits-_-0.6.2-faf29727b3dbdfa09cfb6f0c881a2a227b5d2bb0-ghc8.6.1.dll`, I have `libHSghc- typelits-_-0.6.2-faf29727b3dbdfa09cfb6f0c881a2a227b5d2bb0.a`, which I have to assume is what is being used by GHC for plugin usage. \\ Does this mean mkPluginUsage should be hashing these files instead? On Windows only? The attached `DsUsage.hs` file is working on my end, inelegant as it may be. It tries looking for .a files if looking for dynamic files (.dll, .so, .dylib) fails. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15234#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
