This package provides small utility to backport GHC bug fix [#12186](https://ghc.haskell.org/trac/ghc/ticket/12186) for GHC versions < 8.2 It works by being specified as the linker, where it will simply do a find and replace on the supplied linker args before passing the result on to the real linker. To build & install, run the following: stack install clr-win-linker Which will copy the resulting executable to the path, usually 'C:\Users\\AppData\Roaming\local\bin' Then specify as the linker when building other packages like so: stack build --ghc-options="-pgml clr-win-linker" And the resulting executables should then get past ghc issue #12186: stack exec clr-test-app
