GHCi is picking up this version but the version doesn't seem usable due to different symbol names. It's been fixed in 8.4. using `lib` is explicitly forcing it to pick the `import library, libicuio.dll.a` which directs it to the right dll. Under normal circumstances, those (libicuio vs icuio) two are *roughly* equivalent. There are some diffences but it should all work out to the same if you have your environment correct. I'm closing it as a duplicate. I'm not sure the release manager would agree that this should be backported into the up and coming ghc 8.4.3 bug- fix release for ubuntu. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15150#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
