there seem to be two main approaches (which both require some testing) 1) build ghc with integer-simple
2) do some static linking tricks on your side, such as those described in http://stackoverflow.com/questions/809794/use-both-static-and-dynamically-linked-libraries-in-gcc, this might entail that you need to know the precise OS / Distro a client is using before you give them a binary, but might make the process much simpler overall (despite its relative hackiness) On Wed, Oct 9, 2013 at 2:22 PM, Carter Schonwald <carter.schonw...@gmail.com > wrote: > I remember Tim Dysinger telling me some incantations needed to statically > link Gmp into the static binary before deployment.
