1) How much effort does it take for a user to install a dynamically-linked ghc executable on Tier 1 platforms? Just download the source and set DYNAMIC_GHC_PROGRAMS=YES? 2) Are the major GHC distributors planning on distributing dynamically-linked ghc by default? GHC HQ, Haskell Platform, http://www.haskell.org/ghc/distribution_packages? Bonus question: 3) How many platforms support Core plugins but not a dynamically linked ghc? I'm hoping the answer is "zero". The availability of a dynamically-linked ghc looks good, according to the wiki pages I found. It's not so clear to me regarding support on Windows. Thank you for your time. P.S. — Here's the wiki pages I read. Their up-to-dateness is not clear to me. Please let me know if you see that I missed something. === Core plugins http://ghc.haskell.org/trac/ghc/wiki/NewPlugins — nub is 2 years old === building and using shared libraries (aka "dynamic libraries") http://ghc.haskell.org/trac/ghc/wiki/Platforms — very much alive and useful http://ghc.haskell.org/trac/ghc/wiki/Status/May13#Dynamiclinking — summarizes GHCI behavior http://ghc.haskell.org/trac/ghc/wiki/SharedLibraries/PlatformSupport — 4 years old http://ghc.haskell.org/trac/ghc/ticket/5620 — good info in comments; 1.5 years old === default behavior of an entire GHC installation http://ghc.haskell.org/trac/ghc/wiki/DynamicByDefault — 8 months old especially http://ghc.haskell.org/trac/ghc/wiki/DynamicByDefault#Windows
